四川省某石材园区职业病危害因素检测与评价

Detection and evaluation of occupational hazard factors in a stone park in Sichuan Province

目的识别、分析与评价四川省某石材园区61家石材加工企业产生的职业病危害因素及危害程度,提出相应的防护对策和措施,预防、控制职业病发生。方法2019年3—9月,对园区61家石材加企业进行了职业卫生学现场调查和主要职业病危害因素的检测。结果总粉尘时间加权平均浓度(CTWA)检测超标率为54.1%,接触水平瞬时超出时间加权平均允许浓度(PC-TWA)值3倍为54.1%;呼尘CTWA检测超标率为46.0%,接触水平瞬时超出PC-TWA值3倍为39.3%;噪声检测超标率为100.0%;手传振动检测超标率21.3%。结论用人单位应做好职业病危害的防护,加强职业健康监护,规范个人防护用品的配备和使用,以更好地保护劳动者健康。

Objective To identify,analyze and evaluate the occupational hazard factors and degree produced by 61 stone processing plants in a stone park of Sichuan Province,put forward corresponding protective countermeasures and measures to prevent and control the occurrence of occupational diseases. Methods From March to September 2019,61 stone processing enterprises in the park were investigated by the field occupational hygiene survey and major occupational hazards detection. Results The over standard rate of time-weighted average concentration(CTWA) of total dust was 54.1%,and the instantaneous contact level of total dust exceeded the permissible concentration-time weighted average(PC-TWA) by three times was 54.1%. The over standard rate of CTWA of respirable dust was 46.0%,and the instantaneous contact level of respirable dust exceeded PC-TWA by three times was 39.3%.The over standard rate of noise was 100.0%. The over standard rate of hand transmitted vibration was 21.3%. Conclusion The employer should improve the the protection of occupational hazards,strengthen occupational health surveillance,and standardize the provision and use of personal protective equipment,so as to better protect the health of workers.
