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物。主要介質均為A類消防物質，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.
