建造中的船舶机舱,是工程最集中、污染最严重的部位。这是由于现代船舶的机舱火都设计成封闭式(一般没有天窗),船台建造结束,船舶下水后,大量工程便集中到机舱。多工种交叉作业,造成舱内烟尘弥漫、空气污浊。夏季烟尘积滞在闷热的舱内,使作业环境更加恶化。舱内电焊、气焊工作量火,舣装工人安装矿棉绝缘材料以及油漆打磨、喷漆,都是机舱有害气体污染的根源。据测试,作业高峰期混合烟尘浓度达13～15mg/m~3,超过国家标准。此外,由于 The engine room under construction is the most concentrated and polluting part of the project. This is because the modern ship’s cabin fire is designed to be closed (usually without skylights), and the construction of the slipway ends. After launching of the ship, a large number of works are concentrated in the cabin. Multi-species cross-job, resulting in diffuse cabin smoke, air pollution. Summer soot stagnant in the hot cabin, the operating environment even worsened. Cabin welding, gas welding workload fire, outfitted workers to install mineral wool insulation and paint grinding, painting, are the source of pollution of cabin noxious gases. According to the test, the peak smoke concentration of 13 ~ 15mg / m ~ 3, exceeding the national standard. Also, thanks
