Occupational health risk assessment for organic solvent in the major posts of printing industry

Abstract

Objective: To evaluate the occupational health risk of organic solvents in major posts of printing industry, and to provide technical reference to take targeted risk control measures. Methods: In January 2021, the contact ratio method was used to assess the occupational health risk of organic solvents in the major posts of 84 printing enterprises in Shantou, and Monte Carto method was used to estimate the probability distribution of risk levels in the majorpostsin January 2021. Results: The highest probability of risk assessment in printing and membranecovering post is Level 4 (high risk) , which are 76.2% and 67.6% respectively; the highest probability of simulation evaluation result in oil blending, dispensing and cleaning post is Level 3 (medium risk) ; and the simulation evaluation result in glueing post are mostly Level 3 (medium risk) and Level 4 (high risk) , the probability of which are 45.7% and 54.3% respectively. Conclusion: The occupational health risk of organic solvents in the major posts is generally middle-high risk level, and then the occupational health risk control of organic solvents in major posts of printing industry should be strengthened.
