[目的]了解密闭空间电焊工作业岗位职业病危害控制情况。[方法]2011年5～6月,对青岛市某船厂船舱内36个电焊工作业岗位进行职业病危害因素检测与评价。[结果]电焊作业时,船舱内噪声、电焊烟尘、锰及其无机化合物的合格率分别为36.11%、5.56%、11.11%,最高检测值分别超标0.08、7.64、17倍,属于不合格;臭氧、一氧化氮、二氧化氮、一氧化碳、二氧化碳的合格率均为100.00%。[结论]青岛市某船厂船舱内电焊工作业岗位职业病危害较为严重。
[Objective] To understand the occupational hazards control in the welding jobs in confined space. [Method] From May to June, 2011, 36 welder jobs in the shipyard of a shipyard in Qingdao were tested and evaluated for occupational hazards. [Result] The qualified rate of noise, welding fume, manganese and inorganic compounds in cabin during welding was 36.11%, 5.56% and 11.11% respectively. The highest detection value exceeded 0.08, 7.64 and 17 times respectively, which was unqualified. , The pass rate of nitric oxide, nitrogen dioxide, carbon monoxide, carbon dioxide is 100.00%. [Conclusion] The occupational hazards of welders in cabin of a shipyard in Qingdao are more serious.
