There are two main reasons for fire accidents. First of all, the design and construction of the cold storage is unreasonable, and no corresponding fire protection measures have been set up. The second is improper manual operation, and the staff lack corresponding professional knowledge.
2. Causes of refrigeration system failure
The reasons for the failure of refrigeration system can be divided into: improper maintenance of refrigeration system, coolie often doing big work and running with illness. After refrigeration, it must be ignored, which leads to the annual inspection of equipment and accelerated aging, thus causing the leakage and exposure of ammonia refrigerant in the refrigeration system.
Secondly, the cold storage design project is imperfect, unlicensed design, no professional technology installation and construction, and some low-priced cold storage construction enterprises use a large number of inferior products or second-hand materials, so that the safety of cold storage can not be effectively guaranteed.
Extended data:
1, fire accident
Fire accident is a frequent phenomenon in the cold storage industry in recent years, especially in an explosion-proof cold storage in Tianjin last year, which caused a large number of casualties and great losses to people's property safety.
2, refrigeration system accident
At present, Freon refrigeration is mostly used in cold storage in China. Freon is a class 4 mild toxic substance, but when the amount of freon in the air reaches a certain level, it will cause suffocation.
When the ammonia in the air is as high as 16% to 25%, it may also cause an explosion accident when it encounters an open flame. With the frequent quality accidents of cold storage system, compressor damage and refrigerant leakage, enterprises suffered heavy losses.
