Abstract
Objective: ICMM occupational health risk assessment model was be used to evaluate the risk of a lead-acid battery enterprise. Methods: In November 2016, a lead-acid battery company in Jiangsu Province was selected as the research object. Based on the occupational health survey data and occupational hazard assessment reports, the ICMM risk assessment model was used to conduct occupational health risks in eight key positions of a lead-acid battery enterprise. The risk assessment results was verified by actual test results. Results: In the quantitative assessment model, the occupational health risk assessment results for the castings and welding positions exposed to lead smoke, and the occupational health risk assessment results for the grinding and dividing positions exposed to lead dust existed unacceptable risks. The occupational health risk assessment results for the ball-milled and plated positions exposed to lead dust existed tolerable risks. The occupational health risk assessment results for the lead-plated and soldered positions exposed to sulphuric acid pastes and acids existed potential risks. In qualitative evaluation matrix method, the occupational health risk assessment results for the castings and welding positions exposed to lead smoke, and the occupational health risk assessment results for the grinding and dividing positions exposed to lead dust existed high risks, the occupational health risk assessment results for other four key positions were considered to be with low risks. Conclusion: The key control points for lead smoke in this enterprise were castings and welding positions; The key control points for lead dust were the grinding and separating brush positions. The quantitative assessment model and the qualitative assessment matrix method in the ICMM model were consistent with the actual test results in the eight health risk assessments of occupational hazards in key positions. Therefore, the method could be applied to the assessment of occupational health risks of the lead-acid battery enterprise. According to the results of the assessment, improvements could be made to high-risk positions and the concentration of occupational hazards in high-risk posts could be reduced to better protect the health of workers.
