应用半定量法评估某油墨制造企业职业病危害风险

Assessment of health risk of occupational hazards in a printing-ink plant with semi-quantitative method

目的评估某油墨制造企业的职业病危害风险。方法应用新加坡有害化学品职业暴露半定量风险评估方法对某油墨制造企业各岗位接触的职业病危害进行风险评估。结果混料岗位矽尘和丙烯酸甲酯浓度超过职业接触限值,风险等级分别为高风险(4级)和中等风险(3级),其他职业病危害因素未超过职业接触限值,风险等级为低风险;研磨和产品检验岗位各种职业病危害因素均未超过职业接触限值,风险等级均为低风险或可以忽略的风险。结论该油墨制造企业混料岗位风险较高,需要采取控制措施降低风险。

Objective To assess the health risk of occupational hazards in a printingink plant in Shenzhen. Methods The occupational hazards at worksites of mixing, grinding and quality checking in a printingink plant were surveyed and the health risk was assessed by semi-quantitative method from Singapore. Results The concentrations of silica and methyl acrylate at mixing worksite were higher than OELs values,and the risk rating was assessed as high and medium respectively;while the risk ratings of other occupational hazards were ranked as low since the concentrations of these hazards at mixing worksite were lower than OELs values. The risk ratings of occupational hazards at grinding and quality checking worksite were assessed as low or negligible since the concentrations of occupational hazards were lower. Conclusion The health risk at mixing worksite was high, and more control measures should be taken.
