大哥，请再帮我翻译以下几句话好吧。

1、空气中浓度超标时，必须佩戴自吸过滤式防毒面具（半面罩）。紧急事态抢救或撤离时，应该佩戴空气呼吸器。
2、空气中粉尘浓度超标时，应该佩戴头罩型电动送风过滤式防尘呼吸器。；可能接触其蒸气时，建议佩戴直接式防毒面具（半面罩）。
3、用控制焚烧法处置。焚烧炉排出的氮氧化物通过洗涤器除去。
4、实行就业前和定期体检。

2、空气中粉尘浓度超标时，应该佩戴头罩型电动送风过滤式防尘呼吸器。；可能接触其蒸气时，建议佩戴直接式防毒面具（半面罩）。
2, the dust concentration in air overweight, they should wear headgear electric powered air purifying respirators and dust. ; Possible exposure to vapor, it is recommended to wear masks Direct (half mask).

3、用控制焚烧法处置。焚烧炉排出的氮氧化物通过洗涤器除去。
3, control incineration disposal. Incinerator emissions of nitrogen oxides through the scrubber to remove.

4、实行就业前和定期体检。
4, the implementation of pre-employment and periodic medical examinations.

希望帮到你，有问题还可以问我哦！谢谢~
