Description

A kind of dangerous goods storage monitoring and early warning system

technical field

The invention relates to the technical field of storage monitoring systems, in particular to a storage monitoring and early warning system for dangerous goods.

Background technique

Dangerous goods are a general term for flammable, explosive, highly corrosive, toxic and radioactive items. When transporting and storing dangerous goods, they should be handled in accordance with the dangerous goods regulations. Dangerous goods are divided into five categories according to their hazard. As far as the general storage rules for ordinary items are concerned, according to the fire hazard of the stored items, our country divides warehouses into five categories: A, B, C, D, and E (category A is the highest). According to the combustion performance and fire resistance limit of warehouse components (walls, columns, beams, floor slabs, roof load-bearing components, evacuation stairs, suspended ceilings), my country divides warehouses into one, two, three, and four fire resistance grades (the highest level of the first grade). ). There is a certain correlation between the classification of fire hazard and the classification of refractory grades. The higher the fire hazard resistance of warehouses, the higher the requirements for refractory grades. Therefore, in practice, there are usually only 15 subdivision warehouses. Dangerous goods should be stored in warehouses with a corresponding level of fire hazard not lower than their fire hazard characteristics according to their physical and chemical properties.
