我们车间有65、150、250和750kg空气锤共四台,并有两台反射加热油炉。车间一旦开始工作,空气锤发出的噪声高达94～98dB,同时排出的废气还污染了车间空气。工作之后工人同志感到身体非常疲劳,并伴有头胀、耳鸣等现象。为了保障工人的身体健康,降低锻造车间的噪声,我们制订了如下治理方案。 Our workshop has a total of four 65,150,250 and 750kg air hammer, and two refueling furnace. Once the workshop started to work, the air hammer emitted noise up to 94 ~ 98dB, while exhaust emissions also polluted the workshop air. After work, the worker’s comrades felt that the body was very tired and accompanied by symptoms of bloating and tinnitus. In order to protect the health of workers and reduce the noise in the forging workshop, we formulated the following treatment plan.
