某纤维素厂职业病控制效果评价

Assessment of the Occupational Disease Control Effect in A Cellulose Plant

采用职业卫生现场调查、职业卫生检测、职业健康检查等方法,评价河北省某纤维素厂职业病危害防护措施及效果。共设噪声检测点13个,检测结果为62.8~81.6d B（A）;氢氧化钠检测点2个,最高容许浓度最大值为0.170 mg/m3;盐酸检测点2个,最高容许浓度最大值为1.8 mg/m3;氯甲烷检测点4个,时间加权平均浓度（CTWA）、短时间接触浓度（CSTEL）均检测结果〈最低检出浓度;环氧丙烷检测点2个,时间加权平均浓度（CTWA）、短时间接触浓度（CSTEL）检测结果均〈最低检出浓度;硫化氢检测点1个,最高容许浓度检测结果〈最低检出浓度;一氧化碳检测点1个,时间加权平均浓度（CTWA）最大值为1.1mg/m3;棉尘检测点4个,CTWA最高为0.55 mg/m3;活性炭粉尘1个,CTWA为0.06 mg/m3;其他粉尘检测点3个,CTWA最高值为4.12 mg/m3。该项目在总体布局、设备布局,建筑卫生学、辅助用室、职业危害因素防护措施、个人防护用品配备、应急救援、职业卫生管理等方面基本符合国家法律、法规及职业卫生标准要求。

Site occupational health investigation, occupational health detection and occupational health examination method were used to assess the occupational disease prevention measures and effect in a cellulose plant in Hebei province. 13 Noise testing points were established, testing results are 62.8 ~ 81.6 d B（ A）; 2 sodium hydroxide testing points, the highest maximum allowable concentration is 0.170 mg /m3; 2 hydrochloric acid testing points, the highest maximum allowable concentration is 1.8 mg/m3; 4 methyl chloride testing points, test results of time weighted average concentration（ CTWA） and short time exposure concentration（ CSTEL） are less than the minimum detection concentration; 2 epoxy propane testing points, test results of time weighted average concentration（ CTWA） and short time exposure concentration（ CSTEL） are less than the minimum detection concentration; 1 hydrogen sulfide testing point, the highest allowable concentration test result is less than the minimum detection concentration; 1 carbon monoxide testing point, the maximum time weighted average concentration（CTWA） is 1.1 mg /m3; 4 cotton dust testing points, maximum CTWA is 0.55 mg /m3; 1 activated carbon dust,CTWA is 0.06 mg /m3; 3 other dust testing points, maximum CTWA is 4.12 mg /m3. The project in the general layout,equipment layout, construction of hygiene, auxiliary room, protection measures against the occupational hazard factors,personal protective equipment, emergency rescue, and other aspects of the occupational health management in line meet the requrement of national laws, regulations and occupational health standards.
