Objective To investigate the type, distribution, level of occupation hazards as well as the protection measures adopted and protective effect achieved in a hydrogen storage alloy powder production line of an enterprise.
Methods An onsite occupational hygienic survey on production process and protection measures was conducted to test and analyze occupational hazards.
Results The production process and facility layout met basic occupational safety and health requirements, but the hygienic protective measures were not properly executed. The levels of occupational hazards including Co, Ni, Mn, and noise in tensity exceeded relevant national standards, but the rare earth dust concentration and the heat level were under the occupational exposure limits.
Conclusion The occupational hazards identified in the selected hydrogen storage alloy powder production line are at high levels, especially industrial toxicants. The enterprise should take feasible occupational hygienic protection measures.
