-
摘要:
目的 调查某企业贮氢合金粉生产线工作场所职业病危害因素种类、分布、危害程度、防护措施及防护效果。 方法 对生产工艺、职业卫生防护措施等进行职业病卫生学现场调查,对危害因素进行采样检测和分析。 结果 该生产线的生产工艺和设备布局合理,但卫生防护措施尚未完全到位,作业点生产性毒物钴(Co)、镍(Ni)、锰(Mn)均有不同程度超标,噪声有5个点不合格,而粉尘浓度、高温均合格。 结论 该生产线职业病危害因素较严重,尤其是生产性毒物,应采取合理可行的防护措施。 Abstract: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.
