目的了解乡镇涂料厂在生产过程中苯、甲苯、二甲苯、丙酮、汽油浓度及其危害情况。方法按照国家有关标准的要求,对5家乡镇涂料厂工作场所空气中5种有机溶剂的浓度进行检测,并对其危害现状进行分析。结果共检测12个点,48个样品,汽油、丙酮均低于国家标准限值,有3家苯系物浓度低于国家卫生标准限值,有1家(D厂)苯的短时间接触浓度(10.6mg/m3)超过卫生标准限值(10mg/m3),有1家(B厂)苯系物浓度联合作用评价值=1.375>1,超过国家标准要求的接触限值。结论在乡镇涂料厂生产过程中的职业病危害因素中,以有机溶剂为重点,其中苯系物为严重的职业病危害因素,特别是对超标的厂家应予重点关注,并提出防治措施的建议。
Objective To understand the concentrations of benzene, toluene, xylene, acetone and gasoline in the process of production of township paint factory and their harmfulness. Methods According to the requirements of relevant national standards, the concentrations of five kinds of organic solvents in the air of five township paint factory workplaces were tested and the status quo of the damage was analyzed. Results A total of 12 points and 48 samples were tested. Gasoline and acetone were all lower than the national standard. Three benzene series compounds were lower than the national standard limit. One short-time benzene concentration (10.6mg / m3) exceeds the limit of 10mg / m3 for hygiene standards, and the combined effect of benzene series concentration in one plant (B plant) is 1.375> 1, which exceeds the national exposure limit. Conclusion Among the occupational hazards in the process of production of township paint factory, organic solvents are the main pollutants. Among them, benzene series compounds are serious occupational hazards, especially for those who exceed the standard, and some suggestions on prevention and control measures should be put forward.
