摘　　要：目的通过对某燃煤火力发电厂工作场所接触化学毒物的作业分级,评估该项目职业病危害程度,为提高用人单位职业病防治工作水平提供基础。方法对某燃煤火力发电厂工作场所空气中存在的化学毒物的种类及接触岗位进行现场调查,借助《工作场所职业病危害作业分级第2部分:化学物》(GBZ/T 229.2-2010)技术标准进行接触化学毒物作业的危害程度分级。结果接触化学毒物的锅炉汽机巡检员、脱硫巡检员、检修运行工、水汽值班员危害作业分级指数均<1,作业级别均为0级,属于相对无害作业;化学值班员、液氨卸车员危害作业分级指数1<G≤6,作业级别均为Ⅰ级,属于轻度危害作业。结论除化学值班员、液氨卸车员,其他接触化学物作业岗位对劳动者健康影响较小;轻度危害作业需通过采取控制工作场所职业病危害因素接触水平、加强职业卫生培训、落实个体防护及定期职业健康检查等措施,减少接触化学毒物对健康的影响。Objective To determine the severity of chemical poison hazards and to improve the level of occupational disease prevention and control work of one coal-fired power plant construction project through applying the classification for chemical poison hazards in workplace.Methods Making survey in the workplace of one coal-fired power plant to identify occupational hazard factors and to define the chemical exposure position,and then classifying the chemical poison in workplace with the ＆quot; Occupational Hazard in the workplace classification-Part 2：Occupational Exposure to Chemicals＆quot; （GBZ/T 229.2-2010）.Results Boiler turbine inspecting for exposure to chemical hazard poison,desulfurization system inspecting,repairman and water vapor watch are grade 0 with grading index 〈 1,belonging to relatively harmless job.Chemicals custodian and liquid am monia unloaders are grade Ⅰ with 1 〈 G≤6,belonging to mild harm job.Conclusions Other chemical exposure post have less impact on workers＆#39;health,except for chemicals custodian and liquid ammonia unloaders.Chemical exposure post may be mildly hazardous by taking measures to reduce the impact on health,such as controlling occupational exposure to occupational hazards in the workplace,strengthening occupational health training,implementing individual protection and regular occupational health checks.
