Objective: To analyze the occurrence of work accidents among Mobile Emergency Service workers and the association with the identified occupational risks., Method: A quantitative, exploratory, descriptive and cross-sectional study conducted with Mobile Emergency Service workers in Rio Grande do Sul, between January 2016 and November 2017, using an online instrument., Results: A total of 265 workers participated. There was a significant association between the occurrence of accidents at work and professional category (p = 0.041); as well as the occurrence of work accidents and the mesoregion (p = 0.015). In the significant associations between the occurrence of accidents at work and occupational risks, accidents with sharps, physical aggression, animal bites, verbal aggression, traffic accidents during commuting and falls were highlighted. In addition, a significant association between the occurrence of an accident at work and work leave (p = 0.000) was found., Conclusion: The occurrences of work accidents during pre-hospital service activities are related to the professional category of workers, the work mesoregion, work leave and the exposure of workers to different occupational risks.

The present study aimed to identify the perceptions of gas station workers about physical, chemical, biological and physiological risk factors to which they are exposed in their work environment; identify types of occupational accidents involving gas station workers and; report the development of a socioenvironmental intervention as a tool for risk communication to gas station workers. A quantitative study was performed with 221 gas station workers in southern Brazil between October and December 2010. Data collection was performed between October to December 2010 via structured interviews. The data were analyzed using SPSS 19.0. The participants identified the following risk types: chemical (93.7%), physical (88.2%), physiological (64.3%) and biological (62.4%). In this sample, 94.1% of gas station workers reported occupational accidents, and 74.2% reported fuel contact with the eyes (p < 0.05). It is concluded that workers perceive risks, and that they tend to relate risks with the occurrence of occupational accidents as an indicator of the dangerous nature of their work environment.

The present study has aimed to identify the perceptions of apprentice welders about physical, chemical, biological, and physiological risk factors to which they are exposed; identify types of occupational accidents involving apprentice welders; and report the development of a socioenvironmental education intervention as a tool for risk communication for apprentice welders. A quantitative study was performed with 161 apprentice welders in Southern Brazil in 2011. Data collection was performed via structured interviews with the apprentice welders about risk perception, occupational accidents, and time experienced in welding. The data were analyzed using SPSS 19.0. The participants identified the following risk types: physical (96.9%), chemical (95%), physiological (86.3%), and biological (51.5%). In this sample, 39.7% of apprentice welders reported occupational accidents and 27.3% reported burning. The inferential analysis showed that the frequency of risk perception factors increases with the length of experience, and apprentice welders who have experienced accidents during welding activity perceive a higher amount of risk factors than those who have never experienced them. It is concluded that apprentice welders perceive risks and that they tend to relate risks with the occurrence of occupational accidents as an indicator of the dangerous nature of their activity.
