通过职业病危害预评价的类比检测和控制效果评价的现场检测,对某新建选煤厂职业病危害防护设施、职业卫生管理进行现场调查。该企业粉尘8 h时间加权平均浓度合格率与类比企业相比差异有统计学意义,各岗位噪声8 h等效连续A声级差异也有统计学意义。通过预评价,新建企业建立了完善的职业病危害防护设施,并建立有效的职业卫生管理体系。
Through on-site testing of analogical detection and control effect evaluation of pre-evaluation of occupational hazards, a field investigation was conducted on occupational hazards prevention facilities and occupational health management in a new coal preparation plant. The 8-h time-weighted average concentration pass rate of the enterprise dust showed a significant difference compared with the analogous enterprises, and the difference of 8-h equivalent continuous A-sound level among the positions was also statistically significant. Through pre-evaluation, the newly established enterprises have established sound occupational hazards protection facilities and established an effective occupational health management system.
