Workers' Exposure to Chemical Risk in Small and Medium-Sized Enterprises: Assessment Methodology and Field Study

This study aimed to develop a state-of-the-art method for assessing chemical risks in small and medium-sized enterprises (SMEs). The method combined desk research findings and the authors' practical knowledge to identify major shortcomings in performing risk assessments at the workplace. Data were collected from nine SMEs across three sectors: agriculture, laboratory research, and conservation and restoration laboratories. On-site observations, focus group discussions, and textual content analysis of occupational safety and health documentation were used to gather information on chemical risks and workers' perceptions. The developed method uses numerical factors to account for the level of conformity with regulations and the duration of exposure to support an estimation of the probability of an incident. The method was designed to enhance risk assessment practices and tackle common issues encountered by SMEs, including the lack of data for estimating probability. Feedback from SMEs involved in the study indicated that the method's performance was satisfactory, with its well-organized information flow and supportive components being particularly valued. The study highlights the importance of effective risk assessment in creating a safer and healthier work environment for workers.
