Analysis of common accidents in cold storage and their causes

In recent years, with the continuous development of the cold chain logistics industry, there are more and more users who need to build cold storage. Once anything develops too fast, all kinds of abuses will gradually surface. , And as long as there are problems, they must be dealt with in time, only in this way can the normal use of the cold storage and the personal safety of the staff be guaranteed.

　　 1. Common accidents in cold storage

　　 1. Fire accident

　　Fire accidents have occurred frequently in the cold storage industry in recent years, especially the explosion of an explosion-proof cold storage in New York last year, which caused a large number of casualties and caused great losses to the people’s property safety.

　　2, refrigeration system accident

Nowadays, most of the international cold storages use Freon for refrigeration. Freon is a grade 4 mildly toxic substance. However, when the amount of Freon in the air reaches a certain level, it will cause suffocation: When the ammonia in the air When the gas is as high as 16% to 25%, it may also cause an explosion when it encounters an open flame. With the frequent occurrence of quality accidents in cold storage systems, the damage of compressors, and the leakage of refrigerants, companies have suffered a lot of losses.

　　 2. Analysis of common causes of accidents

　　 1. The cause of the fire accident

There are two main reasons for fire accidents. The first is that the design and construction of the cold storage is unreasonable and there is no corresponding fire protection measures. The second is that the manual operation is inappropriate and the staff lacks the corresponding professional knowledge. .

　　2. Reasons for refrigeration system failure

The reasons for the failure of the refrigeration system can be divided into the refrigeration system not being properly maintained, often doing small work, and running with illness. After the cold storage is built, you must not leave it alone, resulting in equipment annual inspection, disrepair, and accelerated aging. As a result, the ammonia refrigerant in the refrigeration system is exposed and exposed. Secondly, the cold storage design engineering is not perfect, unlicensed design, no professional technical installation and construction, some low prices, the cold storage construction enterprises of the system use a large number of defective or second-hand materials, so that the safety of the cold storage cannot be effectively guaranteed.
