Risk Analysis on Occupational Hazard of a Printing Company
-
摘要:
目的 对某印刷企业进行职业病危害风险分析。 方法 运用职业卫生现场调查、职业卫生检测、职业健康检查等方法收集数据,结合职业病防护设施、个人防护状况等进行职业病风险评估。 结果 该企业所使用的化学品包括印刷油墨、润版液、润版添加剂、计算机直接制版(CTP)显影液及溶剂汽油等,生产过程中可能接触到苯、甲苯、二甲苯、正己烷、环己烷、异丙醇、溶剂汽油及机器运转产生的机械噪声等职业病危害因素。经检测化学性职业病危害因素均低于相关限值,6个噪声作业岗位中3个岗位不符合相关限值要求。现场检查作业人员均未佩戴防毒口罩,仅轮印车间作业人员佩戴防噪耳塞。各印刷车间仅设机械排风,且空调未设置新风系统。 结论 该企业主要职业病危害因素为噪声,应加强噪声的防护,同时关注化学性职业危害因素的风险控制。 Abstract:Objective To conduct risk analysis on occupational hazards based upon a cross-sectional assessment of a printing company. Methods A comprehensive risk analysis was performed on the data and documents collected from occupational health field sruvey, hazardous substances monitoring, and occupational health examination, as well as on protection equipment and individual protection status. Results The chemicals used in the printing company included printing ink, fountain solution, additive agent, computer-to-plate (CTP) developer, and solvent gasoline. Potential occupational hazards during the printing process were benzene, toluene, xylene, n-hexane, cyclohexane, isopropyl alcohol, solvent gasoline, and noise from operating machines. The test results showed that the chemical hazards met the related national limits, but three out of six workstations with noise exposure failed. All field workers were not respirator equipped, and only ear-plug(s) were equipped for those in rotary printing workshop. Forced ventilation was installed in each workshop, but there was no fresh-air device installed in the air conditioning systems. Conclusion Noise is the main occupational hazard in the printing company. Future work should focus on the protection and control of occupational noise and chemical hazards.
