Objectives Following an earthquake that occurred in middle Italy in 2009, the involved territory hosted in 10 years thousands of construction sites. The aim of this study is to assess inhalable, respirable, and respirable crystalline silica exposure of the construction workers involved in the rebuilding activities. Methods Six construction companies joined the study and hosted the air sampling activities. We identified four work tasks: bricklayer and similar; scaffolder and carpenter; manual demolition; other tasks. We reported 8‐h time‐weighted concentrations. Results The “All tasks” geometric mean concentration of inhalable dust was 4.73 mg/m3 and the higher, TLV exceeding exposure was observed for “Manual demolition workers” (13.92 mg/m3, GM). The “All tasks” geometric mean concentration of respirable dust was 0.25 mg/m3 and no TLV‐exceeding exposure (geometric mean values) was observed among the work‐related groups. About the respirable crystalline silica dust exposure, the “All tasks” average concentration was 0.004 mg/m3. No TLV‐exceeding exposure was observed among the whole data sample. Conclusions The comparison of the results shows that manual demolition workers are exposed to high levels of inhalable dust, exceeding the TLV‐TWA (Threshold Limit Values‐Time Weighted Average) limit of 10 mg/m3. About the respirable dust concentration, none of the analyzed work task dust concentrations exceeded the TLV‐TWA limit of 3 mg/m3 (geometric mean values). Measurements of respirable crystalline silica dust have shown levels below the threshold limit value of 0.025 mg/m3. Our findings overall match with the available scientific data.

Purpose. The SARS-CoV-2 pandemic has affected all aspects of everyday life worldwide, including the entire working sector. This study aims to evaluate the response capacity of some Italian companies to the emergency about workers' health and safety. Methods. Data were cross-sectional, collected by a specially drafted 19-item checklist sent to 60 enterprises located in the province of L'Aquila, Abruzzo, Italy. Results. Forty-one companies (68%) responded by filling in the checklist; more than 50% have fewer than 50 employees each and most of the companies belong to the food industry and the financial services. Adherence to the containment measures for the COVID-19 emergency was analysed, especially relating to job organization, social distancing, sanitization and specific training. Large enterprises and the banking sector showed ductile work reorganization according to the containment measures compared to small companies and the food sector. Conclusions. Italian companies have shown a good response to the regulatory restrictions resulting from the SARS-CoV-2 emergency. This is a worthy premise for the imminent management of Phase 2, with the progressive reopening of Italian companies.

Following an earthquake occurred in the middle Italy in 2009, the involved territory hosted in ten years thousands of construction sites. The aim of this study is to assess the chemical exposure of the construction workers involved in the reconstruction of the city. To assess the exposure we collected 91 air samples to quantify the occupational exposure to airborne dusts and free crystalline silica dusts. Six construction companies joined the study and hosted the air sampling activities. We identified 4 work tasks: bricklayer and similar; scaffolder and carpenter; manual demolition; other tasks. Personal air sampling was performed by using the SKC AirCheck XR5000 sample pumps. Respirable dust and respirable crystalline silica dusts were collected by using a GS-3 Cyclones and 25 mm PVC filters; inhalable dust was collected by using a I.O.M. sampler and 25 mm PVC filters. The analyses were carried out by using gravimetric determination. Sampling time varied from 4 to 8 hours. The geometric mean values of inhalable dust concentration for the work tasks was: 3,65 mg/m 3 for scaffolder and carpenter; 18,16 mg/m 3 for manual demolition workers; 8,76 mg/m 3 for bricklayer and similar; 6,33 mg/m 3 for other work tasks. The geometric mean values of respirable dust concentration for the work tasks was: 0,67 mg/m 3 for scaffolder and carpenter; 0,92 mg/m 3 for manual demolition workers; 0,72 mg/m 3 for bricklayer and similar; 0,45 mg/m 3 for other work tasks. About the Crystalline Free Silica dust exposure, the average concentration in mg/m 3 was: 0,0038 for manual demolition workers, 0,0057 for scaffolder and carpenter, 0,004 for bricklayer and similar, 0,0035 for other tasks. The comparison of the results shows that manual demolition workers are exposed to considerably high levels of inhalable dusts, exceeding the ACGIH TLV-TWA limit of 10 mg/m 3 . About the respirable dust concentration, none of the work tasks dust concentration exceeded the ACGIH TLV-TWA limit of 3 mg/m 3 . Measurements of crystalline silica dust have shown levels below the threshold limit value of 0,025 mg/m 3 . This is in line with the average concentrations of respirable dust.

The ASL1 workplace prevention and safety service in Abruzzo has been conducting workplace inspections on agricultural and livestock farms in the province of L'Aquila since 2011, mainly in the areas of Avezzano, Sulmona and L'Aquila. The agricultural sector in Abruzzo is characterized by high rates of accidents and the ratio of fatal injuries/total injuries is higher than the industry and services sector.To evaluate the presence or absence of safety devices , i.e. compliance or otherwise with regulations for tractors, and of any variable factor that could be associated with the safety of the vehicle.Between 2011 and 2013, 98 farms in the province of L'Aquila were inspected. The data resulting from the inspections was collected by the use of a checklist. An univariate logistic regression analysis was conducted in which the vehicles that complied with regulations were considered as the dependant variable, and the age of the tractor owner, the acres of worked land and the type of farm were considered as explanatory variables. Statistical elaboration was carried out using the Stata 12 programme.Out of a total of 298 tractors that were checked, 64.8% did not comply with regulations due to absence or unsuitability of one or more safety devices such as: a protective device in case of overturning; retention system of the driver; mounting and dismounting from the vehicle; protection of moving parts and hot parts; PTO (Power Take Off) protection device. A significant association between non-compliance of vehicles and the age of the owner and acres worked was observed, whereas no statistical significance was observed for the association with the farm type variable.Our study showed that farms where the owner's age is between 50 and 64 years and where more acres of land are worked are those where the agricultural or forestry tractors had lower levels of compliance with regulations.
