Risk assessment on occupational hazards in automobile maintenance industry / 预防医学

ABSTRACT

Objective To investigate the occupational hazards in automobile maintenance industry in Hangzhou and to provide field-research based evidence for prevention and control. Methods We visited 12 workshops of automobile maintenance to investigate the actors of occupational hazards, examine the protective facilities, and evaluate the occupation-related risk using MES method. Results The factors of occupation-related hazards at polishing posts met the criteria. At the painting posts in the painting room, the factors of chemical hazards satisfied the criteria, however, the levels of xylene and butyl acetate exceeded the standard lines in some enterprises when the ventilation system was close. The noise was higher than the limit at a few posts of sheet metal. The ventilation in spray paint room and the dust collector in dry mill room work well. The risks of occupational hazards at grinding, painting, and sheet metal posts were slightly harmful. Conclusion The occupational hazard factors in automobile repair enterprises were much more complicated. The noise hazard of the sheet metal posts was relatively prominent.
