近年来,随着教学、科研的发展,高等院校的部分实验室常常利用家用电冰箱来保存某些易挥发的试剂,认为电冰箱内温度低,存放那些低沸点的化学危险品,比较安全。 由于实验室人员缺乏电冰箱的安全使用知识,去年11月,我院高分子材料系的一台200立升雪花牌家用电冰箱,因使用不当而突然发生爆炸,冰箱门被炸出三米多远,幸好无人,否则后果不堪设想。事后通过调查了解,主要是由于家用电冰箱的电器装置都不是防爆型的,当冰箱内的温度控制开关随着冷藏室的额定温度自动跳开或闭合时,常常会产生电火花,导致发生爆炸事故。
In recent years, with the development of teaching and scientific research, some laboratories in colleges and universities often use domestic refrigerators to store some volatile reagents. They think that the temperature in the refrigerators is low, and those low-boiling chemical dangerous goods are stored. Safety. In November last year, a 200 liter snow flake household refrigerator in the department of polymer materials in our hospital suddenly exploded due to improper use. The refrigerator door was blown out by three meters Fortunately, no one, otherwise the consequences could be disastrous. After investigation through the investigation, mainly due to household appliances are not explosion-proof electrical appliances, when the refrigerator temperature control switch with the rated temperature of the freezer automatically jump open or closed, often have a spark, resulting in the occurrence Explosion accident.
