目的识别、分析液化天然气(LNG)接收站工程的职业病危害因素及其危害程度,探讨该类工程职业病危害的关键控制部位和岗位,为该类工程的职业病防治管理提供依据。方法采用现场调查、职业病危害因素检测等方法对该类工程职业病危害进行调查分析。结果该类工程存在的职业病危害因素有电焊烟尘、硫化氢、甲烷、苯、甲苯、二甲苯、正己烷、锰及其化合物、臭氧、噪声、低温LNG、工频电场、紫外辐射以及高温天气作业等。用人单位在产生职业病危害因素的工作场所采取了设置职业病防护设施,为作业工人配备了必需的个人防护用品,并制定了各种职业卫生管理制度。对各职业病危害因素的职业卫生检测结果中,除A、B两接收站工作场所噪声分别超标5.5～10.6 dB(A)、6.7～14.3 dB(A)外,其余检测结果均符合职业接触限值的要求。结论 LNG接收站工程主要职业病危害为噪声作业和高温天气作业,应重点控制。用人单位应加强职业卫生管理,做好职业病防护和职业健康监护,以确保劳动者的职业健康。
Objective To identify and analyze the occupational hazards and the degree of harm to the liquefied natural gas (LNG) receiving station project, and to explore the key control positions and positions of the occupational hazards of such projects and provide the basis for the prevention and control of occupational diseases in such projects. Methods Investigate and analyze the occupational hazards of such projects by means of on-the-spot investigation and detection of occupational hazards. Results The occupational hazards of such projects include welding fumes, hydrogen sulfide, methane, benzene, toluene, xylene, hexane, manganese and their compounds, ozone, noise, low temperature LNG, power frequency electric field, UV radiation and high temperature weather Wait. The employer has set up occupational disease protection facilities in workplaces that produce occupational hazards and equipped working workers with the necessary personal protective equipment and formulated various occupational health management systems. Among occupational health test results of all occupational hazards, all the test results are in line with occupational exposure limits except that the noise in workplaces of A and B receiving stations exceeds 5.5 ~ 10.6 dB (A) and 6.7 ~ 14.3 dB (A), respectively. Request. Conclusion The main occupational hazards of LNG receiving station project are noise operation and high-temperature weather operation, and should be given priority control. Employers should strengthen occupational health management, occupational disease protection and occupational health monitoring, to ensure the occupational health of workers.
