Objective To make sure the occupational hazard factors and its hazard rating of some medical equipment product in the process of the production and to determine the occupational- disease- prevention facilities and the effect of the occupational health management measures. Methods The methods of field occupational health investigation,detection test,the occupational health examination and checking table and other methods were applied to collect data and information,combined with the occupational- disease- prevention facilities,personal occupational disease protection level,and the contact level of the occupational- disease- inductive factors of the operators was evaluated. Results First,operators of sandblasting machine contact with silicious dust and contacting time in total had weighted concentration reaching 1. 6 mg /m3 in the workshop,and weighted concentration of breathing time had reached 0. 3 mg / m3,exceeded the national health standards,the rest of the concentration of toxic substances should meet the national occupational health standards after rectification in accordance with the national occupational health standards. Secondly,operators of ultrasonic cleaning equipment had contacted noise intensity reaching 86. 2 d B,and operators of ultrasonic plastic welding machine operator had contacted noise intensity reaching 104. 8 d B,what's more,operators of powder machine operator had contacted noise intensity reaching 85. 2 d B,all exceeded the national occupational health standards but other operators of other working positions had contacted noise intensity met the national occupational health standards. Conclusion Occupational- disease- inductive factors are mainly caused by benzene,toluene,xylene,copper smoke,nitrogen dioxide,sodium hydroxide,potassium hydroxide and other dust( dust),welding smoke,silica dust,noise and ultraviolet radiation,and benzene,toluene,xylene silica dust and noise are considered as the key control points,so engineering protection measures and the effectiveness of individual protective measures should be taken during the working.
