Background Job-exposure matrices (JEMs) are often used for exposure assessment in occupational exposure and epidemiology studies. However, general population JEMs are difficult to find and access for workers in the United States of America. Objective We aimed to use publicly available information to develop a JEM-like exposure assessment method to determine exposure to a wide range of occupational agents in a wide range of occupations for US general population studies. Methods We used information from the US Department of Labor's Occupational Information Network database (O*NET) for 19,636 job tasks and 974 civilian occupations. We used automated keyword searches to identify 1,804 job tasks that involved exposure to 50 occupational agents. We had 2 reviewers determine whether each identified job task actually involved exposure to the 50 occupational agents. We had a third reviewer, a certified industrial hygienist, assess any job task and exposure for which the first 2 reviewers disagreed. For each U.S. Census 2010 occupation code, we used this information to derive 3 exposure variables for each occupational agent: ever exposure, number of job tasks of exposure, and frequency of exposure. Results Our keyword searches identified a median of 10 (interquartile range [IQR]: 43.75) job tasks for each occupational agent, and the maximum was 308. We determined job tasks actually involved exposure to 45 occupational agents, including solvents, air pollution, pesticides, radiation, metals, etc. We derived the 3 exposure variables for these 45 occupational agents for 516 U.S. Census 2010 occupation codes. The median percentage for ever exposure to individual occupational agents was 1.16% (IQR: 1.74%), and the maximum was 11.43%. Conclusions Our JEM-like exposure assessment method based on O*NET information can be used to determine exposure to a wide range of occupational agents in a wide range of occupations for the US general population.

Introduction: The routine use of heat-producing tools in the perioperative setting generates surgical smoke. Surgical smoke poses a known health hazard for perioperative staff working in the operating room. Objective: The objective of this best practice project was to promote evidence-based practices regarding surgical plume management in a pediatric operating room. Methods: This project was guided by the JBI Model of Evidence-Based Healthcare and used the JBI Practical Application of Clinical Evidence System and the Getting Research into Practice audit and feedback strategy to promote evidence-based practices regarding surgical smoke management in a pediatric operating room. Seven audit criteria representing best-practice recommendations were used. A baseline audit was conducted, followed by the implementation of multiple strategies developed by the key stakeholders. The project was finalized with a follow-up audit to determine any changes in compliance with best-practice recommendations. Results: Baseline audit data indicated an average of 41% compliance with best practices across all audit criteria, revealing the need for significant improvement in five of the seven criteria. Three barriers were identified and strategies were implemented, including the development and implementation of an educational module and a surgical smoke exposure risk assessment tool. Follow-up audits showed an overall improvement of 30% among five of the seven audit criteria. Conclusions: This project yielded improvements with best practices for surgical smoke management in the perioperative setting. However, additional work is required to ensure the sustainability of best practices in this setting. [ABSTRACT FROM AUTHOR]

Our study examined the occupational health and safety (OHS) issues that impact environmental public health workforces across various health departments in the U.S. The objective was to generate an OHS risk profile for the workforce to inform future preventative strategies. Data for our study were collected via a cross-sectional online survey (N = 158) supplemented by a virtual focus group (N = 7) discussion to confirm and explore some of the themes and data items that emerged from the survey. Descriptive statistics were used to provide information about the variables in the data sets and to identify relationships between them. Nonparametric tests were used to determine statistical significance between two or more variables that were not normally distributed. Focus group data were analyzed thematically. Our study indicates that the environmental health (EH) workforce in the U.S. is exposed to a range of significant workplace hazards. Some of the OHS concerns identified in our study are similar to those observed in Australia and New Zealand. Biological and chemical exposures appear to be important hazards; however, further study is required to determine the nature and mechanism of these hazards within the EH workforce. Furthermore, our study suggests that the COVID-19 pandemic had a significant impact on the health and safety of EH professionals. [ABSTRACT FROM AUTHOR]

Noise-induced hearing loss (NIHL) continues to be a pervasive problem for the nation's workforce, particularly the nation's mining personnel. As one of the leading health and safety organizations in the world, the National Institute for Occupational Health and Safety (NIOSH) in Pittsburgh maintains a Hearing Loss Prevention Program (HLPP) to conduct research to reduce NIHL loss among the nation's miners. This document provides a brief overview of this HLPP, describing some of the research techniques involved in the development of engineering noise controls, methods for the development of administrative noise controls, and some of the products available to the public to protect the nation's workers hearing.

Asian and Asian Americans (A/AA) are a group overlooked in general health outcomes but especially occupational safety and health outcomes. In the United States, the beauty service microbusiness industry (e.g., nail salons) predominantly employs immigrant Asian women who regularly encounter a plethora of occupational hazards (e.g., harmful chemical exposures -toluene, formaldehyde, bloodborne pathogens, fungi. However, due to the precariousness of beauty service jobs, cultural and linguistic barriers, and social determinants of health, A/AA beauty service workers face complex occupational safety and health challenges that require interdisciplinary collaboration and cultural competency to address. This commentary will discuss a multi-level approach including specific outreach partners that will offer the required diverse skillsets necessary for improving the occupational safety and health for this worker population in this microbusiness industry. Implications and suggestions for interventions and policy changes are also recommended utilizing the National Institute on Minority Health and Health Disparities' Research Framework.

We developed an opioid hazard awareness module for inclusion in required miner safety refresher training. The module was disseminated throughout the United States and post-training surveys showed improved knowledge and positive response to the training. Clinicians can improve care of high-risk worker patients by recommending employer support for such training. Objective: In response to elevated risk factors, an opioid hazard awareness training for the sand, stone, and gravel mining sector was developed and embedded in annual safety training. Methods: After positive results from a prior study among Massachusetts workers, a revised training was disseminated across the United States. Two hundred post-training surveys were obtained and compared with results from the Massachusetts cohort. Results: Participants' knowledge about opioid-based medications, confidence in talking to a doctor about opioids and/or to a coworker about their own use of opioids, and ability to refer struggling coworkers to resources improved. Massachusetts respondents had slightly more favorable responses. Both cohorts had strong positive views of the training. Conclusions: These results highlight the feasibility and effectiveness of opioid hazard prevention training for a high-risk worker population. [ABSTRACT FROM AUTHOR]

The fumes created from welding activities present a unique occupational hazard. Due to the complex processes which govern fume formation, the characterization of welding fumes is difficult. Emission factors (EFs) are one method to characterize fume formation from different processes and scenarios. This paper reviews the development of EFs and similar metrics both historic research which contributed to the US EPAs AP-42 summary of welding emission factors released in 1995, and more recent research initiatives. Through a critical analysis of what research has been done in this area and the strength of the emission factors developed, this paper proposes a set of recommendations for future research. Research on emission factors for gas metal arc welding (GMAW) is the most complete amongst the different types of electric arc welding. Despite it being generally known that flux core arc welding (FCAW) creates significant fume emissions compared to some of the other processes few studies have looked at FCAW since the AP-42. Shielded metal arc welding is also under-researched particularly in terms of metal-specific emission factors. The influence of different welding activity parameters such as welding location, speed or current is well defined for GMAW but requires more attention for other welding processes. Further effort towards compiling and comparing available emission factor data of quality, evaluating the available data statistically and organizing this data in a practically useful way is required. The availability of reliable emission factors will allow the development or improvement of exposure modelling tools that would be very useful for exposure assessment when monitoring is not practical.s [ABSTRACT FROM AUTHOR]

Latino day laborers (LDL) are a vulnerable population of workers facing considerable risk for occupational injury. Under the guidance of our Community Advisory Board, we developed and tested the feasibility, acceptability and preliminary effects of Vales+Tú (You Are Worth More), a workplace injury risk-reduction program implemented by promotores on street-corners where LDL seek employment. The program was informed by theoretical perspectives emphasizing individual and group agency and self-determination. A pilot three-arm cluster-randomized community trial was conducted among 75 LDL. The intervention arms consisted of an individualized Brief Motivational Interview, a Group Problem Solving activity and a standard of care control (OSHA safety cards). We met our study goal of 25 LDL per intervention arm, and contacted 88% of participants post intervention. Participants evaluated the interventions favorably. At post-test, the Brief Motivational Interview group reported significant reductions in exposure to workplace hazards and increases in risk-reduction practices. The Group Problem Solving participants showed significant reductions in exposure to hazards (t -test −4.16, p < 0.001). Both intervention groups increased their reliance on corner peers, a measure of social support. Standard of care participants increased in self-efficacy to work safely. Overall, the only significant different between the three study conditions was in self-efficacy. These findings provide evidence of the feasibility and acceptability of Vales+Tú and show preliminary program efficacy. A large-scale replication trial will permit a more formal modeling of the study findings. Clinical Trial Registration (ClinicalTrials.gov): NCT04378348. [ABSTRACT FROM AUTHOR]

Objectives This study: (i) assessed the relationship between noise exposure and injury risk, comprehensively adjusting for individual factors, psychosocial stressors, and organizational influences; (ii) determined the relative importance of noise on injuries; (iii) estimated the lowest observed adverse effect level (LOAEL) of noise on injury risk to determine the threshold of noise considered hazardous to injuries; and (iv) quantified the fraction of injuries that could be attributed to hazardous noise exposure. Methods In this cross-sectional study at 10 US surface mine sites, traditional mixed effects, Poisson regression, and boosted regression tree (BRT) models were run on the number of reported work-related injuries in the last year. The LOAEL of noise on injuries was identified by estimating the percent increase in work-related injuries at different thresholds of noise exposure using a counterfactual estimator through the BRT model. A population attributable fraction (PAF) was quantified with this counterfactual estimator to predict reductions in injuries at the LOAEL. Results Among 18 predictors of work-related injuries, mine site, perceived job safety, age, and sleepiness were the most important predictors. Occupational noise exposure was the seventh most important predictor. The LOAEL of noise for work-related injuries was a full-shift exposure of 88 dBA. Exposure ≥88 dBA was attributed to 20.3% (95% CI: 11.2%, 29.3%) of reported work-related injuries in the last year among the participants. Conclusions This study further supports hypotheses of a dose–response relationship between occupational noise exposure and work-related injuries, and suggests that exposures ≥88 dBA may increase injury risk in mining.

In the United States, medicolegal death investigation practices and policies pertaining to sudden unexpected deaths are mandated by state government. Practices vary across states, which contributes to inconsistency in job prerequisites and training. In preparation for a study focused on occupational safety and health of medicolegal death investigators in their on‐scene and follow‐up activities, a scoping review was conducted to document known occupational safety risks and health‐related conditions associated with death investigation. Searches used Boolean and subject heading operators both broad and narrow in scope, and search terms included scene responder, hazard, investigator, forensic pathology, injury, and safety. Twenty‐five articles met inclusion criteria, which included seventeen survey‐mixed method designs, two systematic reviews, five quasi‐experimental designs, and one case study. Twelve articles addressed mental health and eleven focused on risks associated with infectious disease. One article addressed the risk of chemical exposure from cyanide among autopsy personnel (including forensic pathologists) and nine included a wide range of employees within the setting of medical examiner or coroner offices. One article, addressing burnout, included employees in a forensic science laboratory setting as well as medicolegal death investigators and two articles included forensic pathologists and medicolegal death investigators. Only one article addressed medicolegal death investigators specifically. Articles addressing occupational and environmental hazards of medicolegal death investigators associated with musculoskeletal, respiratory, cardiovascular, radiological, nuclear, electrical, or explosive threats were not identified. There is little published about safety risks inherent in conducting death investigations. Research is needed to adequately inform health promotion and injury prevention strategies.

A quiz about workplace hazards impacting the environmental health workforce is presented.

All-terrain vehicle (ATV) crashes are one of the leading causes of death and injury in agriculture across the United States. Use of ATVs is highly prevalent in rural areas and has seen an increase in their application for a variety of agricultural work tasks. Empirical research on the use of these vehicles for agricultural tasks and associated injuries is limited, especially in the United States. Moreover, little is known about the risk factors associated with ATV-related injuries while doing farm work. A comprehensive review was conducted to evaluate the current injury burden of ATV use in agriculture, the need for future research, and possible solutions related to agricultural ATV safety. Potential injury prevention approaches are evaluated based on the hierarchy of control, including elimination or substitution (using side-by-side vehicles instead of ATVs or modifying ATV design), engineering control (operator protection devices), administrative authority (regulations and standards in the United States and around the world), training, and use of personal protective equipment. In addition, vehicle nomenclature, risk factors, and crash mechanisms are reviewed. Recommendations to decrease the likelihood of ATV crashes and injuries are provided. [ABSTRACT FROM AUTHOR]

Workers in the electric power industry commonly perform physically demanding jobs in hot environments, which combined with the protective clothing worn, places them at risk of disease and health problems related to occupational heat stress. With climate change fueling an increase in the occurrence of hot weather, a targeted approach to heat stress management within the industry is needed. To better understand current heat management practices and identify opportunities for refinement, we conducted an exploratory survey among 33 electric utility companies operating in the United States (n = 32) and Canada (n = 1). Forty-six employees responsible for health and safety of company workers completed 26 questions assessing heat stress as a workplace hazard and heat management practices within five categories: (1) use and administration of heat stress management program; (2) surveillance of heat stress and heat strain; (3) job evaluation and heat-mitigation guidance; (4) education and training programs; and (5) treatment of heat-related illness. While a majority of the respondents (87.0%) indicated heat stress is a workplace hazard and their organization has a heat stress management program (78.3%), less than half reported performing real-time monitoring of heat stress in the workplace (47.8%) or tracking worker heat strain (19.6%) (i.e., physiological response to heat stress). However, most organizations indicated they conducted pre-job evaluations for heat stress (71.7%) and implemented an employee training program on managing heat stress (73.9%). The latter included instruction on various short- and long-term heat-mitigation guidance for workers (e.g., use of work exposure limits, hydration protocols) and the prevention (52.2%) and treatment (63.1%) of heat-related illnesses. Altogether, our survey demonstrates that although many companies employ some form of a heat management program, the basic components defining the programs vary and are lacking for some companies. To maximize worker health and safety during work in hot environments, a consensus-based approach, which considers the five basic components of a heat management program, should be employed to formulate effective practices and methodologies for creating an industry-specific heat management strategy.

Carbon monoxide (CO) exposure levels encountered by wildland firefighters (WLFs) throughout their work shift can change considerably within a few minutes due to the varied tasks that are performed and the changing environmental and fire conditions encountered throughout the day. In a U.S. Forest Service study during the 2009–2012 fire seasons, WLFs from 57 different fires across the U.S. were monitored for CO using CO data-logging detectors while an observer recorded worker tasks, fire characteristics, and environmental conditions at scheduled intervals. Exposures to CO for 735 WLF's work shifts were analyzed to assess the effect of variations among work tasks, fire characteristics, and environmental conditions. Geometric mean full shift time-weighted averages were low at 2.4 parts per million (ppm) and average length of work shift was 11 hr and 15 min. The task with the highest mean CO exposure was sawyer/swamper at 6.8 ppm; workers performing that task had an estimated 9 times higher odds of a having a 1-min CO measurement exceeding 25 ppm than the referent pump task (OR = 8.89, 95% CI = 1.97, 40.24). After adjusting CO exposure limits for shift length, elevation, and work level, 2% and 4% of the WLF's work shifts exceeded the National Institute for Occupational Safety and Health's recommended exposure level and the American Conference of Governmental Industrial Hygienist's threshold limit value, respectively. In regression modeling, variables that were significantly associated with elevated levels of CO exposure included: task, fuel model, wind orientation, crew type, relative humidity, type of attack, and wind speed. In the absence of instruments such as CO detectors that can determine and alert WLFs to elevated CO levels, recognition of the conditions that lead to elevated levels of CO exposure can assist WLFs to effectively use administrative controls, such as work rotations, to minimize exposures.

Objectives: Non-fatal injuries in the high risk US Dungeness crab fishery have been under-documented, despite their potential for lost work time and income, long-term disability, and early unwanted retirement. The Fishermen Led Injury Prevention Program (FLIPP) characterized injuries in this fishery, in order to identify work hazards and inform injury control measures. Methods: The FLIPP injury survey was completed by 426 fishermen in 23 Washington, Oregon, and California fishing ports prior to the 2015–2016 Dungeness crab season; 413 (97%) provided injury information for this analysis. Participants indicated whether they had been injured in the previous 12 months, described the injury, any treatments received, and whether the injury limited their ability to work. Results: Participants were mostly male (98%), more than half (56.6%) worked as deckhands, and reported considerable fishing experience (median = 14 years, interquartile range 5–27). Eighty-nine fishermen (21.5%) reported an injury incident in the past year, of which 49 (55.1%) were limiting. The 89 incidents yielded 102 injuries, of which nearly two-thirds were sprains/strains (23, 22.5%), surface wounds/bruises (17, 15.0%), cuts (18, 17.6%), or punctures (11, 10.8%). More severe injuries, including eight fractures, were rare. The majority of injuries received either no treatment (27, 26.5%) or first aid (35, 34.3%); clinical care was less common (22, 21.6%), and emergency care rare (3, 2.9%). Conclusion: One in five Dungeness crab fishermen reported an injury incident in the previous year. Most injuries were not severe and did not result in clinical care, but approximately half were work-limiting. Control measures must account for the remote and resource-limited workplace in commercial fishing. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to determine the effectiveness of curricula for improving knowledge and attitudes pertaining to pesticide exposure and heat illness among immigrant Latino farmworkers. Methods: A pesticide safety curriculum informed by the revised Worker Protection Standard (WPS) was tested against an attention placebo-controlled curriculum (heat illness) in a sample of Latino farmworkers (N= 127). Results: Pesticide safety knowledge increased in the overall sample, but did not differ by curriculum assignment. Pesticide safety behavioral intentions increased among participants in the pesticide safety curriculum but decreased among those in the other curriculum (P < 0.05). Heat illness knowledge and behavioral intentions increased more for farmworkers assigned to the heat illness than the pesticide safety curriculum. Conclusion: The developed curricula show good promise for meeting the spirit of the revised WPS and for reducing the burden of heat-related fatality and morbidity among Latino farmworkers.

Objective: The aim of this study was to measure musculoskeletal disorders and occupational risk factors among railroad maintenance-of-way (MOW) workers. Methods: Four thousand eight hundred sixteen active, retired, and disabled members of the Brotherhood of Maintenance of Way Employes Division (BMWED) completed a survey. Results: Compared with U.S. employed men, adjusting for age, race, and region, active male MOW workers were more likely to report "repeated lifting, pushing, pulling, or bending" at work (74.6% vs 46.9%), not enough staff (88.1% vs 65.2%), and a diagnosis of carpal tunnel syndrome (7.9% vs 3.6%). They were less likely to report management priority on workplace health and safety (59.37% vs 94.8%), ability to make job decisions on their own (68.4% vs 87.7%), and supervisor support (60.3% vs 90.8%) (all comparisons, P< 0.001). Conclusion: Prevention programs should address risk of musculoskeletal disorders and occupational hazards faced by MOW workers. [ABSTRACT FROM AUTHOR]

Harvesting timber for lumber produces is among the most dangerous occupations in the United States. While not exhaustive, the literature on these dangers is substantial. However, several other smaller harvesting forest based industries put workers at risk in unique ways. Relatively little research has been published on these activities, but preliminary exploratory research, summarized here, suggests that besides the risks inherent in being in the forest, workers face some unique workplace risks, the frequency and consequences of which are augmented by the social determinants that characterize the workforce. This paper provides a brief overview of the workplace safety risks to forest green and mushroom harvesters and cedar block cutters in the Northwest. We also point out the social characteristics of these workforces that potentially aggravate these risks and the health impacts therefrom. [ABSTRACT FROM AUTHOR]

Objective: Ants, bees, hornets, wasps, and yellow jackets (insects in Order Hymenoptera) are potentially a serious concern to outdoor workers, as the venom from their stings can cause life-threatening allergic reactions. This study assessed the impacts of Hymenoptera stings and related worker training regimes of forestry workers across the United States (US). Methods: A survey was distributed to nearly 2,000 outdoor workers in the forestry industry from four US regions (South, West, Northeast, and Midwest). Results: Ants are a primary concern in the South, with >75% of participants reporting ant stings within the last 5 years. Bees, hornets, wasps, and yellow jackets are a concern for surveyed foresters in all US regions, with 60–70% and 75–93% of participants, respectively, having been stung by bees or hornets/wasps/yellow jackets within the last 5 years. Despite such a large number of participants experiencing stings, nearly 75% of participants were not concerned about being stung or their reaction to stings. Approximately, 70% of participants reported not having received any safety training related to Hymenoptera from their employers. Conclusion: No significant difference was shown in the number of foresters stung at work between safety trained and non-safety trained participants. However, it was significantly more likely for participants to carry a first aid kit if they had received Hymenoptera safety training. Consequently, more comprehensive and frequent training should be considered to help reduce risk of exposure to Hymenoptera. [ABSTRACT FROM AUTHOR]

Forest workers, including loggers, foresters, and wildland firefighters, are regularly exposed to some of the most fatal occupational environments in the United States. These hazardous work environments may become even more complex and dynamic when subject to bark beetle outbreaks that have resulted in significant tree mortality. The impacts of tree death from bark beetles are significant, with the cumulative 17-year (2000–2016) footprint for bark beetle caused tree mortality estimated at 54 million acres. However, how workers think about and act in these environments is understudied. This study, therefore, approaches the issue of beetle kill and forest worker safety by examining the perspectives or workers themselves. Its contribution is to leverage ethnographic research to provide insights that can generate new research questions, better inform outreach, and ultimately improve worker safety outcomes. The resulting insights show that beetle kill was understood by workers as a hazard that increased the complexity and dynamism of the work environment, making situational awareness both more necessary and more difficult to maintain. While much research about situational awareness focuses on hazardous situations, it is suggested that building adequate situational awareness should also include broader considerations of organizational communication, as well as training and experience considered over the course of entire careers.

The article discusses that approximately 8 million health care workers have the potential for exposure to drugs that may be hazardous to health through the preparation of anticancer regimens in the U.S. It mentions hazardous drugs are defined by their association with genotoxicity, carcinogenicity, teratogenicity, fertility impairment and serious organ toxicity at low doses; and also mentions safety standards have been developed within the U.S. and internationally for health care providers.

Noise control is a well understood and important engineering skill. The science has been developed to address operational needs of being quiet on the one hand, and avoiding hearing loss on the other, both in industry and military operations. Noise control is also the first priority step in systems safety risk mitigation for noise hazards, as evidenced in U.S. industry by the requirement stated in Federal OSHA regulation 1910.95: "(b)(1) When employees are subjected to sound exceeding those listed in Table G-16, feasible administrative or engineering controls shall be utilized." In actual practice, engineering controls are of first preference, while the second step is administrative noise controls, reducing noise exposures by removing personnel from high-noise environments. The third is the use of personal protective equipment (PPE), commonly known as earmuffs and earplugs. Each of these topics is discussed herein. The U.S. Navy has developed and/or implemented many groundbreaking noise control efforts on ships, and that provides the basis of discussion in this article. This article, as an overview of noise control, also addresses issues associated with high-noise environments and consideration of noise control techniques. [ABSTRACT FROM AUTHOR]

Objectives Workers using flavoring formulations containing diacetyl and 2,3-pentanedione may be at risk of inhalational exposure, as these volatile hazardous chemicals are emitted from the bulk material, especially at elevated temperatures. However, flavoring formulations that contain diacetyl and 2,3-pentanedione might not list these ingredients because they are generally recognized as safe to ingest, may be part of a proprietary mixture deemed a trade secret, or may not be required to be listed if they are present at <1% composition. The objective of this study was to investigate whether potential inhalational hazards present in flavoring samples were reported as chemical ingredients on their corresponding safety data sheets (SDSs). Methods A convenience sample of 26 bulk liquid flavorings obtained from two coffee roasting and packaging facilities in the USA was analyzed for 20 volatile organic chemicals present in the headspaces of vials containing flavoring liquids using gas chromatography-mass spectrometry. Flavoring samples were included in the study if headspace analysis results and SDSs were available. Flavoring samples included hazelnut, French vanilla, amaretto, chocolate, and caramel as well as some flavoring mixtures containing added fruit flavors such as cherry and raspberry. The presence of a chemical in the flavoring formulation was then compared to the ingredient list on the SDSs. Results All the flavoring SDSs contained trade secret designations. None of the SDSs listed diacetyl or 2,3-pentanedione. Headspace analyte concentrations revealed that diacetyl was present in 21 of 26 samples (81%) with a maximum concentration of 5.84 × 104 µg m−3 in flavor 18 (caramel). 2,3-Pentanedione was present in 15 flavors (58%) with a maximum concentration of 3.79 × 105 µg m−3 in flavor 24 (oatmeal cookies). Conclusions A majority of the flavorings tested had diacetyl, 2,3-pentanedione, or both as volatile constituents in the headspace. These chemicals were not listed on the SDSs, but inclusion of diacetyl and 2,3-pentanedione on SDSs would serve to protect downstream users from unrecognized exposure and potential respiratory disease. The headspace technique presented here is a viable tool to rapidly screen for volatile hazardous chemicals that may be present in flavoring formulations. Facilities that use flavorings should be aware that constituents in flavorings may present a potential inhalational hazard even if not identified as such by the SDS. A precautionary approach is warranted when working with flavorings, including exposure monitoring and effective exposure control strategies such as containment and local exhaust ventilation.

Despite longstanding recommendations for the safe handling of hazardous drugs, it's not known whether nurses—including those who are pregnant—wear protective gloves and gowns when administering chemotherapeutic drugs. This study examines this practice among nurses in the Nurses' Health Study 3. Background: Many antineoplastic (chemotherapeutic) drugs are known or probable human carcinogens, and many have been shown to be reproductive toxicants in cancer patients. Evidence from occupational exposure studies suggests that health care workers who have long-term, low-level occupational exposure to antineoplastic drugs have an increased risk of adverse reproductive outcomes. It's recommended that, at minimum, nurses who handle or administer such drugs should wear double gloves and a nonabsorbent gown to protect themselves. But it's unclear to what extent nurses do. Purpose: This study assessed glove and gown use by female pregnant and nonpregnant nurses who administer antineoplastic drugs in the United States and Canada. Methods: We used data collected from more than 40,000 nurses participating in the Nurses' Health Study 3. The use of gloves and gowns and administration of antineoplastic drugs within the past month (among nonpregnant nurses) or within the first 20 weeks of pregnancy (among pregnant nurses) were self-reported via questionnaire. Results: Administration of antineoplastic drugs at any time during their career was reported by 36% of nonpregnant nurses, including 27% who reported administering these drugs within the past month. Seven percent of pregnant nurses reported administering antineoplastic drugs during the first 20 weeks of pregnancy. Twelve percent of nonpregnant nurses and 9% of pregnant nurses indicated that they never wore gloves when administering antineoplastic drugs, and 42% of nonpregnant nurses and 38% of pregnant nurses reported never using a gown. The percentage of nonpregnant nurses who reported not wearing gloves varied by type of administration: 32% of those who administered antineoplastic drugs only as crushed pills never wore gloves, compared with 5% of those who administered such drugs only via infusion. Conclusion: Despite longstanding recommendations for the safe handling of antineoplastic and other hazardous drugs, many nurses—including those who are pregnant—reported not wearing protective gloves and gowns, which are considered the minimum protective equipment when administering such drugs. These findings underscore the need for further education and training to ensure that both employers and nurses understand the risks involved and know which precautionary measures will minimize such exposures.

Background: Modern U.S. dairy farm operations present multiple safety hazards which may result in worker injuries, illnesses and fatalities. The U.S. industry trend towards large-herd milking operations, especially in the Western U.S., necessitates an increased number of workers on each farm. The U.S. dairy workforce is comprised of an increasing percentage of immigrant workers with limited English proficiency which presents a safety training challenge. Our objective was to develop, deliver and evaluate safety awareness training to U.S. dairy farm workers using mobile tablets as a personal learning environment. Methods: A non-random sample of 1,436 dairy workers received safety awareness training on a mobile device platform. Kirkpatrick Levels 1, 2 and 3 training effectiveness evaluations were performed. Results: Approximately 58.7% of training participants received a middle school education, and 22.7% were from Guatemala who reported K’iche’ as their native language. A statistically significant large effect size suggests safety knowledge was gained among training participants when comparing post-test scores to pre-test scores (Level-2). Training participants rated their training experience favorably (Level-1), and applied knowledge gained in their daily work activities three months after training (Level-3). Conclusion: Our findings suggest the utilization of mobile learning techniques is an effective means to deliver safety awareness training content to dairy workers. Dairy worker safety training should be culturally, linguistically, and literacy appropriate and comprehensive in nature to include all applicable dairy safety hazards. Our observations support the use of mobile devices as just one component of a more comprehensive health and safety management program on farms. [ABSTRACT FROM AUTHOR]

It cites a table that looks at examples of exposure control.

Many health care organizations are making changes to their hazardous medication surveillance program (HMSP) in response to United States Pharmacopeia (USP) <800> standards. Absence of best practices for HMSPs and limitations on the ability of such programs to correlate health effects identified on surveillance with workplace exposures historically have left health care institutions to determine if and how to design an HMSP for their workforce. Within this article one approach to the design of an HMSP is discussed and resources such as a health questionnaire and declination form are included that could be modified or adopted by other health care organizations. This information is intended to generate further discussion and collaboration among leaders of employee occupational health services on a national level to address the benefits and challenges of HMSPs.

The article focuses on interaction of health and safety of health care workers and patients in the healthcare system of the U.S. It discusses the report titled "To Err is Human" in 2000 published by the U.S. Institute of Medicine related to patient safety. It mentions a Summit hosted by the American College of Occupational and Environmental Medicine (ACOEM) and the Underwriters Laboratories Integrated Health and Safety Institute (ULIHSI) related to the issues.

Objectives: Heat stress exposure limits based on wet-bulb globe temperature (WBGT) were designed to limit exposures to those that could be sustained for an 8-h day using limited data from Lind in the 1960s. In general, Sustainable exposures are heat stress levels at which thermal equilibrium can be achieved, and Unsustainable exposures occur when there is a steady increase in core temperature. This paper addresses the ability of the ACGIH® Threshold Limit Value (TLV®) to differentiate between Sustainable and Unsustainable heat exposures, to propose alternative occupational exposure limits, and ask whether an adjustment for body surface area improves the exposure decision. Methods: Two progressive heat stress studies provided data on 176 trials with 352 pairs of Sustainable and Unsustainable exposures over a range of relative humidities and metabolic rates using 29 participants wearing woven cotton clothing. To assess the discrimination ability of the TLV, the exposure metric was the difference between the observed WBGT and the TLV adjusted for metabolic rate. Conditional logistic regression models and receiver operating characteristic curves (ROC) along with ROC's area under the curve (AUC) were used. Four alternative models for an occupational exposure limit were also developed and compared to the TLV. Results: For the TLV, the odds ratio (OR) for Unsustainable was 2.5 per 1°C-WBGT [confidence interval (CI) 2.12-2.88]. The AUC for the TLV was 0.85 (CI 0.81--0.89). For the alternative models, the ORs were also about 2.5/°C-WBGT, with AUCs between 0.84 and 0.88, which were significantly different from the TLV's AUC but have little practical difference. Conclusions: This study (1) confirmed that the TLV is appropriate for heat stress screening; (2) demonstrated the TLV's discrimination accuracy with an ROC AUC of 0.85; and (3) established the OR of 2.5/°C-WBGT for unsustainable exposures. The TLV has high sensitivity, but its specificity is very low, which is protective. There were no important improvements with alternative exposure limits, and there was weak evidence to support metabolic rate normalized to body surface area. In sum, the TLV is protective with an appropriate margin of safety for relatively constant occupational exposures to heat stress. [ABSTRACT FROM AUTHOR]

Silicosis is the oldest know occupational pulmonary disease. It is a progressive disease and any level of exposure to respirable crystalline silica particles or dust has the potential to develop into silicosis. Silicosis is caused by silica particles or dust entering the lungs and damaging healthy lung tissue. The damage restricts the ability to breathe. Exposure to silica increases a worker's risk of developing cancer or tuberculosis. This special report will provide background history of silicosis in the U.S., including the number of workers affected and their common industries. Over the years, these industries have impeded government oversight, resulting in silicosis exposure clusters. The risk of acquiring silicosis is diminished when industry implements safety measures with oversight by governmental agencies. Reputable authorities believe that the current innovative drilling techniques such as fracking will generate future cases of silicosis in the U.S. if safety measures to protect workers are ignored.

Aim To identify occupational exposures for home health-care nurses and aides. Background Home health-care workers' occupational injury rates in the USA are higher than the national average, yet research on causative exposures and hazards is limited. Methods Participants were interviewed about annual frequency of occupational exposures and hazards. Exposure and hazard means were compared between home health-care nurses and aides using a Wilcoxon two-sample test. Results A majority of the sample was over 40 years old and obese, potentially increasing injury risks. Home health-care nurses performed more clinical tasks, increasing exposure to blood-borne pathogens. Home health-care aides performed more physical tasks with risk for occupational musculoskeletal injuries. They also dispensed oral medications and anti-cancer medications, and were exposed to drug residue at a frequency comparable to home health-care nurses. Both groups were exposed to occupational second-hand smoke. Conclusions Establishing employee safety-related policies, promoting healthy lifestyle among staff, and making engineered tools readily available to staff can assist in decreasing exposures and hazards. Implications for nursing management Implications for nursing management include implementation of health-promotion programmes, strategies to reduce exposure to second-hand smoke, ensuring access to and education on assistive and safety devices, and education for all staff on protection against drug residue.

The article presents a qualitative analysis of the situational pressures that influence firefighters' decision making with respect to personal protective equipment (PPE), and it mentions how the research reveals that firefighter identity, goal seduction, and situation aversion were the strongest factors of PPE non-compliance among the U.S. firefighters that were studied. A gap between demonstrated safety knowledge and lack of connection to self-reported safety behaviors is also assessed.

A first person narrative is presented that explores the author's experience of getting the Leader in the Field award for 2019.

Background: Masons have the highest rate of overexertion injuries among all construction trades and rank second for occupational back injuries in the United States. Identified ergonomic solutions are the primary method of reducing exposure to risk factors associated with musculoskeletal disorders. However, many construction workers lack knowledge about these solutions, as well as basic ergonomic principles. Construction apprentices, as they embark on their careers, are greatly in need of ergonomics training to minimize the cumulative exposure that leads to musculoskeletal disorders. Apprentices receive safety training; however, ergonomics training is often limited or non-existent. In addition, apprenticeship programs often lack "soft skills" training on how to appropriately respond to work environments and practices that are unsafe. The SAVE program - SAfety Voice for Ergonomics - strives to integrate evidence-based health and safety training strategies into masonry apprenticeship skills training to teach ergonomics, problem solving, and speaking up to communicate solutions that reduce musculoskeletal injury risk. The central hypothesis is that the combination of ergonomics training and safety voice promotion will be more effective than no training or either ergonomics training alone or safety voice training alone.Methods/design: Following the development and pilot testing of the SAVE intervention, SAVE will be evaluated in a cluster-randomized controlled trial at 12 masonry training centers across the U.S. Clusters of apprentices within centers will be assigned at random to one of four intervention groups (n = 24 per group): (1) ergonomics training only, (2) safety voice training only, (3) combined ergonomics and safety voice training, or (4) control group with no additional training intervention. Outcomes assessed at baseline, at the conclusion of training, and then at six and 12 months post training will include: musculoskeletal symptoms, general health perceptions, knowledge of ergonomic and safety voice principles, and perception and attitudes about ergonomic and safety voice issues.Discussion: Masons continue to have a high rate of musculoskeletal disorders. The trade has an expected increase of 40 % in the number of workers by 2020. Therefore, a vetted intervention for apprentices entering the trade, such as SAVE, could reduce the burden of musculoskeletal disorders currently plaguing the trade.Trial Registration: ClinicalTrials.gov Identifier: NCT02676635 , 2 February 2016.

Commercial fishing continues to have one of the highest rates of occupational fatalities compared with other work sectors in the United States. Attitudes/beliefs among Vietnamese shrimp fishermen of the Gulf of Mexico may influence behaviors that are risk factors for fatal and nonfatal injuries. The study employs a community trial with quasi-experimental pretest/posttest intervention design. An advisory group made up of key stakeholders including representatives from the US Coast Guard was assembled. A survey was designed using the Theory of Planned Behavior as the theoretical framework. Three community groups at port sites along the Texas/Louisiana Gulf Coasts were identified. Focus groups were convened at each site to select priority areas for risk intervention using training and awareness measures. Initial and follow-up surveys were administered pre-/post-interventions for each of the three community groups (2008, n = 217 completed surveys; 2012, n = 206 completed surveys). The follow-up survey was condensed and "intent to act" questions were added for the priority concerns identified (noise-induced hearing loss, machinery/winches, and fatigue). Statistically significant changes (P ranging from.000 to.042) were observed in selective attitude/belief responses for hearing/noise and fatigue. Intent to action or to adopt the intervention was high among all three groups of shrimp fishermen (hearing conservation, 82.4%; machinery/winch safety, 94.6%; fatigue awareness, 95.3%). Simple, yet culturally appropriate training and awareness measures in the form of visual and written safety messages favorably influence attitudes, beliefs, and behavioral intent related to priority risk factors identified by Vietnamese commercial shrimp fishermen along the Texas and Louisiana Gulf Coasts.

Introduction: There is a paucity of data available to assess the occupational health and safety risk associated with exposure to monoclonal antibodies. Industry standards and published guidelines are conflicting or outdated. Guidelines offer contrary recommendations based on an array of methodological approaches. This survey aimed to describe current practices, beliefs and attitudes relating to the handling of monoclonal antibodies by Australian medical, nursing and pharmacy clinicians. Methods: An electronic survey was distributed between June and September 2013. Respondents were surveyed on three focus areas: institutional guideline availability and content, current practices and attitudes. Demographic data relating to respondent and primary place of practice were also collected. Results: A total of 222 clinicians completed the survey, with representation from all targeted professional groups and from a variety of geographic locations. 92% of respondents reported that their institution prepared or administered monoclonal antibodies, with 87% specifically handling anti-cancer monoclonal antibodies. Monoclonal antibodies were mostly prepared onsite (84-90%) and mostly within pharmacy clean-rooms (75%) and using cytotoxic cabinets (61%). 43% of respondents reported access to institutional monoclonal antibody handling guidelines with risk reduction strategies including training and education (71%), spill and waste management (71%), procedures for transportation (57%) and restricted handling (50%). Nurses had a stronger preference towards pharmacy manufacturing than both doctors and pharmacists for a range of clinical scenarios. 95% of all respondents identified that professional or regulatory body guidelines are an important resource when considering handling practices. Conclusion: Monoclonal antibodies are most commonly handled according to cytotoxic drug standards and often in the absence of formal guidelines. [ABSTRACT FROM AUTHOR]

The Occupational Safety and Health Act of 1970 and the Workers Right to Know laws later in that decade were signature moments in the history of occupational safety and health. We have examined how and why industry leaders came to accept that it was the obligation of business to provide information about the dangers to health of the materials that workers encountered. Informing workers about the hazards of the job had plagued labor-management relations and fed labor disputes, strikes, and even pitched battles during the turn of the century decades. Industry's rhetorical embrace of the responsibility to inform was part of its argument that government regulation of the workplace was not necessary because private corporations were doing it.

Objectives. Using the social-ecological model, we hypothesized that the home residences of injured workers would be clustered predictably and geographically. Methods. We linked health care and publicly available datasets by home zip code fortraumatically injured workers in Illinois from 2000 to 2009. We calculated numbers and rates of injuries, determined the spatial relationships, and developed 3 models. Results. Among the 23 200 occupational injuries, 80% of cases were located in 20% of zip codes and clustered in 10 locations. After component analysis, numbers and clusters of injuries correlated directly with immigrants; injury rates inversely correlated with urban poverty. Conclusions. Traumatic occupational injuries were clustered spatially by home location of the affected workers and in a predictable way. This put an inequitable burden on communities and provided evidence for the possible value of community-based interventions for prevention of occupational injuries. Work should be included in health disparities research. Stakeholders should determine whether and how to intervene at the community level to prevent occupational injuries. [ABSTRACT FROM AUTHOR]

Objectives: Asbestos has been used in a broad variety of industrial products, including clutch discs of the transmission system of vehicles. Studies conducted in high-income countries that have analyzed personal asbestos exposures of transmission mechanics have concluded that these workers are exposed to asbestos concentrations in compliance with the US Occupational Safety and Health Administration (US OSHA) occupational standards. Clutch facings are the friction component of clutch discs. If clutch facings are sold separated from the support, they require manipulation before installation in the vehicle. The manipulation of asbestos containing clutch facings is performed by a group of mechanics known as riveters, and includes drilling, countersinking, riveting, sanding, and occasionally grinding, tasks that can potentially release asbestos fibers, exposing the mechanics. These manipulation activities are not reported in studies conducted in high-income countries. This study analyzes personal asbestos exposures of transmission mechanics that manipulate clutch facings. Methods: Air sampling campaigns in two transmission repair shops (TRS) were conducted in November 2012 and July 2013 in Bogotá, Colombia. Four workers employed in these TRS were sampled (i.e. three riveters and one supervisor). Personal samples (n = 39), short-term personal samples (n = 49), area samples (n = 52), blank samples (n = 8), and background samples (n = 2) were collected in both TRS during 3-5 consecutive days, following US National Institute for Occupational Safety and Health (US NIOSH) methods 7400 and 7402. Asbestos samples were analyzed by an American Industrial Hygiene Association accredited laboratory. Results: On at least one of the days sampled, all riveters were exposed to asbestos concentrations that exceeded the US OSHA permissible exposure limit or the Colombian permissible limit value. Additionally, from the forty-seven 30-min short-term personal samples collected, two (4.3%) exceeded the US OSHA excursion limit of 1 f cm"3. Conclusions: In this study, we identified that the working conditions and use of asbestos containing transmission products expose transmission mechanics to asbestos concentrations that exceed both the Colombian and OSHA standards. The potential consequences for the health of these workers are of great concern. [ABSTRACT FROM AUTHOR]

Aim To explore catalysts to, and circumstances surrounding, patient-to-worker violent incidents recorded by employees in a hospital system database. Background Violence by patients towards healthcare workers (Type II workplace violence) is a significant occupational hazard in hospitals worldwide. Studies to date have failed to investigate its root causes due to a lack of empirical research based on documented episodes of patient violence. Design Qualitative content analysis. Methods Content analysis was conducted on the total sample of 214 Type II incidents documented in 2011 by employees of an American hospital system with a centralized reporting system. Findings The majority of incidents were reported by nurses (39·8%), security staff (15·9%) and nurse assistants (14·4%). Three distinct themes were identified from the analysis: Patient Behaviour, Patient Care and Situational Events. Specific causes of violence related to Patient Behaviour were cognitive impairment and demanding to leave. Catalysts related to patient care were the use of needles, patient pain/discomfort and physical transfers of patients. Situational factors included the use/presence of restraints; transitions in the care process; intervening to protect patients and/or staff; and redirecting patients. Conclusions Identifying catalysts and situations involved in patient violence in hospitals informs administrators about potential targets for intervention. Hospital staff can be trained to recognize these specific risk factors for patient violence and can be educated in how to best mitigate or prevent the most common forms of violent behaviour. A social-ecological model can be adapted to the hospital setting as a framework for prevention of patient violence towards staff. [ABSTRACT FROM AUTHOR]
