Abstract: [目的]了解南海某海上拖轮舱内噪声水平及工人接触噪声情况,为拖轮职业病防治提供依据.[方法]在拖轮停靠码头补给时,按照海上负荷作业工况,开启相关设备对拖轮主要工作岗位的噪声进行定点测量,对主要员工的噪声接触情况进行调查,并计算40 h等效声级.[结果]南海某海上拖轮主机、辅机、艏推间、空压机、舵机房、空调间、集控间、驾驶室、医务室、住舱、餐厅定点噪声检测结果显示,医务室和餐厅噪声声级超过国际海事组织MSC.337(91)《船上噪声等级规则》限值.轮机长、大管轮、二管轮、三管轮、机匠、机工、电机员7个工种工人的40 h等效声级分别为95.94 dB(A)、99.51 dB(A)、99.51 dB(A)、99.51、99.71 dB(A)、99.71 dB(A)、96.42 dB(A),全部超过我国标准限值.[结论]该拖轮作业工人噪声接触水平较高,应采取相应的措施减少噪声的接触,并做好职业健康监护.
