目的明确建设项目产生的职业病危害因素,分析其危害程度及对劳动者健康的影响,并提出职业病危害的关键控制点和防护的特殊要求,从源头控制或消除职业病危害,保护劳动者健康。方法通过职业卫生现场调查、职业健康检查、职业卫生检测等方法收集数据并分析资料。结果该企业的总体布局、生产工艺和设备布局、建筑卫生学要求、卫生辅助用室、个人使用的职业病防护用品、职业卫生管理基本符合《工业企业设计卫生标准》(GBZ1-2010)的相关要求;主焊线二保焊操作员电焊烟尘时间加权平均浓度(C-TWA)为6.80 mg/m3,超过职业卫生标准限值4.80 mg/m3;清漆喷涂室清洗操作位甲苯、二甲苯短时间接触浓度(C-STEL)分别为101 mg/m3和284 mg/m3,超过职业卫生标准限值100 mg/m3;清漆喷涂操作位甲醛最高容许浓度(MAC)为1.70 mg/m3,超过职业卫生标准限值0.50 mg/m3。结论该企业为职业病危害较重的建设项目,需要在防尘、防毒、防噪方面采取措施,防止职业病发生。
OBJECTIVE To clarify the hazards of occupational diseases caused by the construction projects and to analyze their harmfulness and their impact on the health of laborers. The key control points of occupational hazards and the special requirements of protection are put forward, and the hazards of occupational diseases are controlled or eliminated at source so as to protect the health of laborers. Methods Collect data and analyze data through occupational health field investigation, occupational health examination and occupational health examination. Results The overall layout, production process and equipment layout, building hygiene requirements, health aids rooms, personal protective equipment for occupational diseases and occupational health management basically met the relevant requirements of the “Hygienic Standard for Design of Industrial Enterprises” (GBZ1-2010) ; The time-weighted average concentration of welding fumes (C-TWA) of main welding wire two welding operators was 6.80 mg / m3, exceeding the limit of occupational hygiene standard 4.80 mg / m3; (C-STEL) were 101 mg / m3 and 284 mg / m3, respectively, which exceeded the limit of occupational hygiene standard of 100 mg / m3. The highest allowable concentration of formaldehyde (1.70 mg / m3) for varnish spraying operation exceeded the occupational health standards Limit 0.50 mg / m3. Conclusion This enterprise is a construction project with a heavy occupational hazard and needs to take measures to prevent occupational diseases from occurring in dust-proofing, anti-poisoning and noise prevention.
