目的探讨铁路焊轨基地职业病危害防护措施。方法通过职业卫生现场调查、职业卫生检测等方法收集数据和资料。结果焊轨基地存在的职业性有害因素有粉尘、氮氧化物、一氧化碳、臭氧、锰及其化合物、噪声、紫外辐射、高温、局部振动和工频电场,检测结果,粉尘在手持打磨工序(CTWA11.2 mg/m3)和仿型磨工序(CTWA9.0mg/m3)超过职业接触限值,钢轨焊机、钢轨打磨、正火机、钢轨校直机、吊锤试验台8 h等效连续A声级超过职业接触限值,其他检测项目符合相关标准要求。在职业病防护设施、职业健康监护、警示标识、职业卫生管理等方面也存在不同程度的问题。结论焊轨基地职业病危害关键控制因素为粉尘和噪声,并在职业病防护设施、职业健康监护、个人防护用品、警示标识、职业卫生管理等方面需完善。
Objective To explore the protective measures against occupational hazards in rail welded rail base. Methods Collecting data and data through occupational health field investigation, occupational health examination and other methods. Results The occupational harmful factors in the base of welded rail were dust, nitrogen oxides, carbon monoxide, ozone, manganese and its compounds, noise, ultraviolet radiation, high temperature, local vibration and power frequency electric field. .2 mg / m3) and profiling process (CTWA9.0mg / m3) Occupational exposure limits, rail welding machine, rail grinding, normalizing machine, rail straightening machine, Sound level exceeds occupational exposure limits, other test items meet the relevant standards. In the occupational disease protection facilities, occupational health monitoring, warning signs, occupational health management, there are different levels of problems. Conclusion The key control factors of occupational hazards in welding base are dust and noise, and need to be improved in occupational disease prevention facilities, occupational health monitoring, personal protective equipment, warning signs and occupational health management.
