摘要: 目的 通过对青海察尔汗盐湖某化工企业氯气危害因素的监测,了解该企业工作场所氯气接触水平,明确重点控制区及关键点,讨论氯气危害控制及治理措施,为盐湖地区类似化工企业氯气危害治理提供参考。方法 2022年7月—2023年4月对青海察尔汗盐湖某化工企业进行氯气职业危害因素调查与检测,按照相关职业卫生标准检测,根据结果定量分析劳动者接触浓度,超标项采取改进控制措施,对改进效果进行验证分析。结果 共检测5个工作场所,其中1个点浓度超标,其余浓度符合要求,氯气处理厂房检测结果超标,浓度为1.34~1.81 mg/m3,职业接触限值为1 mg/m3,超限率最高为81.00%。采取改进措施后氯气浓度从1.81 mg/m3降至0.19 mg/m3,下降率为89.50%,符合职业接触限值要求。结论 在察尔汗盐湖地区化工企业重点关注设备腐蚀氯气泄露问题,结合当地环境条件采取特殊工程防护措施控制氯气危害,创造安全的生产环境,切实保护劳动者职业健康。

Abstract: Objective Through the investigation and detection of the hazards of chlorine in a chemical enterprise in Qarhan Salt Lake in Qinghai Province,to understand the level of chlorine gas exposure in the workplace of the enterprise,clarify the key control areas and key points,discuss the control and treatment measures of chlorine gas hazards,and provide reference for the management of chlorine gas hazards in similar chemical enterprises in the salt lake area. Methods From July 2022 to April 2023,a investigation and testing of chlorine gas occupational hazard factors in a chemical enterprise in Qarhan Salt Lake in Qinghai Province were carried out according to relevant occupational health standards,and the exposure concentration of workers was quantitatively analyzed according to the results.Improvement control measures were taken for the excessive items,and the improvement effect was verified and analyzed. Results A total of 5 workplaces were tested,with 1 point exceeding the concentration limit and the rest meeting the requirements. The chlorine treatment workshop exceeded the limit with a concentration of 1.34-1.81 mg/m3,and the occupational exposure limit was 1 mg/m3,with the highest exceedance rate of 81.00%. After taking improvement measures,the concentration of chlorine gas decreased from 1.81 mg/m3 to 0.19 mg/m3,with a decrease rate of 89.50%,which met the requirements of occupational exposure limits. Conclusion Chemical enterprises in Qarhan Salt Lake area should pay close attention to the leakage of chlorine gas from equipment corrosion,take special engineering protection measures to control chlorine gas hazards in combination with local environmental conditions,create safe production environmental conditions,and effectively protect the occupational health of workers.
