有人说,化学危险物品最容易发生事故的季节是夏天.夏天的高温对化学危险物品确实是诱发事故的重要原因之一.不过这并不意昧着到了冬季,化学危险物品就没有危险了.实践证明,冬季是火灾的多发季节,对化学危险物品,人们只能加强管理而不可掉以轻心.冬季气温下降,人们为了御寒,往往要把门窗关闭得严严实实的,通风换气的条件较差.有一些生产或贮存危险物品的场所,如果有可燃性的蒸汽,或可燃性气体,就容易积聚起来,当在一定范围内的空气当中达到爆炸浓度极限时,遇到火源就会引起爆炸火灾.在这种情况下,因为出口是堵着的,安全泄压面积不够,就容易造成惨重伤亡.因此,作好冬季室内的通风换气是很重要的.
Some people say that the season in which dangerous chemicals are most prone to accidents is summer, and high temperatures in summer are indeed one of the major causes of accidents for chemical dangerous goods, but this does not mean that hazardous chemical products are not dangerous in winter. Prove that winter is the season of fire, chemical dangerous goods, people can only strengthen management and can not be taken lightly.Winter temperature drop, people in order to keep warm, often have to close the doors and windows was tightened, ventilation conditions are poor. There are a number of places where dangerous goods are produced or stored that can easily build up if flammable vapors or flammable gases accumulate. Explosion fires can occur when a source of ignition is reached when a concentration of air reaches a certain limit of exposure In this case, because the exit is blocked, and the safety relief area is not enough, it is easy to cause heavy casualties, so it is very important to ventilate the winter indoor air.
