摘要
为了掌握职业性噪声对长输管道工程作业人群听力的影响,对某天然气管道工程具有代表性的输气站场的噪声及作业员工听力情况进行调查。结果表明,各输气站场的噪声强度不同,首站输气岗8h等效声级最高99.1dB(A),高于职业接触限值,其余站场输气岗8h等效声级均符合职业接触限值要求。164名接噪员工中有1人需要复查,经复查除外了噪声作业健康损害,目前来看,职业性噪声未对该工程作业员工的听力造成损伤。
In order to grasp the influence of occupational noise on the hearing of workers in long-distance pipeline project,the noise of representative stations and the hearing condition of the workers were investigated.The results showed that the noise intensity of each station was different.The maximum 8 hsound level of the first station gas transmission post was 99.1 dB(A),which was higher than the occupational exposure limit.The equivalent sound level of 8 hin other stations was in line with the requirement of occupational contact limit.One of the 164 noise exposed workers needs to be reexamined.The health damage caused by noise operation is excluded from the examination.At present,occupational noise does not cause hearing damage to the engineering workers.
