精制的對(duì)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(yīng)副產(chǎn)物。主要介質(zhì)均為A類(lèi)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(xiǎn)化學(xué)物質(zhì)會(huì)引起灼傷。當(dāng)設(shè)備啟動(dòng)和停止時(shí)，大量的氮?dú)饪赡軙?huì)導(dǎo)致窒息甚死亡。對(duì)苯二酸工廠中，由鈷“液位計(jì)”和大型空氣壓縮機(jī)單元引起的高分貝噪聲損害，可能對(duì)人體造成輻射損害，都是危險(xiǎn)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.
