精制的对苯二甲酸装置具有多种易燃，易爆，有毒和有害的原料，辅助材料和反应副产物。主要介质均为A类消防物质，并具有一定的毒性危害。其次，高压蒸汽高温材料和危险化学物质会引起灼伤。当设备启动和停止时，大量的氮气可能会导致窒息甚死亡。对苯二酸工厂中，由钴“液位计”和大型空气压缩机单元引起的高分贝噪声损害，可能对人体造成辐射损害，都是危险的危害。

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.
