某化工厂一工人上厕所,在蹲下的一瞬间,“轰”的一声着火燃烧,屁股被烧伤。事故发生后经查实,起火原因是厂里漏泄的苯液流进厕所的粪坑里,使厕所周围存在着苯蒸气与空气的混合气体,而该工人上身穿的是的确良衬衫,下身穿的是晴纶线裤,在脱晴纶裤时,产生了静电并引燃苯蒸气。静电是某些物体之间的相互摩擦,破坏了物体原子中正负电荷的平衡,发生电荷的转移而产生的。静电极易引起爆炸、火灾和静电电击。因此,易燃易爆作业场所必须谨 A chemical plant workers on the toilet, in the moment of squatting, “boom” as soon as the fire burning, buttocks were burned. After the accident was verified, the cause of the fire is the leakage of benzene plant effluent into the toilet cesspools, toilet around the presence of benzene vapor and air mixture, and the workers wearing a good shirt, wearing the Acrylic line pants, in the removal of acrylic pants, the static electricity and ignite benzene vapor. Static electricity is the friction between some objects, destroyed the balance of the positive and negative charges in the object atoms, resulting in the transfer of charge. Electrostatic discharge can easily cause explosion, fire and electrostatic shock. Therefore, flammable and explosive workplace must be careful
