目的了解木业加工职业病危害现状,为预防职业病提供依据。方法对某木业加工厂进行现场调查,对有害作业岗位进行职业病危害因素检测与评价。结果该厂各岗位粉尘短时间接触在0.67～72.33mg/m3之间,超限倍数为0.22～72.33倍,检测合格率34.62%,粉尘时间加权平均浓度检测在0.06～46.67 mg/m3,检测合格率46.15%;噪声8 h等效连续A声级75.69～94 dB(A)之间,合格率69.70%;苯、甲苯、二甲苯、环氧氯丙烷、甲醛、乙酸异丁酯短时间接触浓度分别为<0.6～43.44 mg/m3之间、<1.2～364.81 mg/m3之间、<3.3～100.50 mg/m3之间、<0.08～0.28 mg/m3之间、甲醛低于最低检出浓度<0.067 mg/m3、乙酸异丁酯低于最低检出浓度<0.6 mg/m3,苯检测合格率73.33%;甲苯检测合格率70.59%;二甲苯检测合格率94.11%;甲醛、环氧氯丙烷和乙酸异丁酯短时间浓度检测全部合格。结论该木器加工厂职业卫生状况不符合国家职业卫生标准,应加强职业卫生监督,采取有效措施,改善劳动条件。
Objective To understand the current status of occupational diseases in wood processing and provide the basis for prevention of occupational diseases. Methods On-site investigation of a wood processing factory was conducted to detect and evaluate occupational hazards in hazardous jobs. Results The short-term contact of dust in various positions of the plant was between 0.67-72.33mg / m3, the limit of multiple was 0.22-72.33 times, the pass rate of test was 34.62%, the weighted average concentration of dust time was 0.06-46.67 mg / m3, the test was qualified Rate of 46.15%; noise 8 h equivalent continuous A sound level 75.69 ~ 94 dB (A), the passing rate of 69.70%; benzene, toluene, xylene, epichlorohydrin, formaldehyde, isobutyl acetate short-term exposure to concentration Respectively, between <0.6 and 43.44 mg / m3, between <1.2 and 364.81 mg / m3, between <3.3 and 100.50 mg / m3 and between <0.08 and 0.28 mg / m3 with formaldehyde below the minimum detectable concentration < 0.067 mg / m3, isobutyl acetate is less than the minimum detectable concentration of <0.6 mg / m3, benzene test pass rate of 73.33%; toluene pass rate of 70.59%; xylene test pass rate of 94.11%; formaldehyde, epichlorohydrin and Isobutyl acetate short-term concentration test all qualified. Conclusion The occupational health status of this wood processing factory does not meet the national occupational health standards. Occupational health supervision should be strengthened and effective measures should be taken to improve working conditions.
