精制的對苯二甲酸裝置具有多種易燃,易爆,有毒和有害的原料,輔助材料和反應副產(chǎn)物。主要介質(zhì)均為A類消防物質(zhì),并具有一定的毒性危害。其次,高壓蒸汽高溫材料和危險化學物質(zhì)會引起灼傷。當設備啟動和停止時,大量的氮氣可能會導致窒息甚死亡。對苯二酸工廠中,由鈷“液位計”和大型空氣壓縮機單元引起的高分貝噪聲損害,可能對人體造成輻射損害,都是危險的危害。
The purified terephthalic acid unit has a variety of flammable, explosive, toxic and harmful raw materials, auxiliary materials and reaction by-products. The main media are class a fire-fighting substances and have certain toxic hazards. Secondly, high pressure steam, high temperature materials and dangerous chemicals can cause burns. When the equipment is started and stopped, a large amount of nitrogen may cause suffocation or even death. High decibel noise damage caused by cobalt "level gauge" and large air compressor unit in p-phthalic acid plant may cause radiation damage to human body, which are dangerous hazards.
