All special purpose buildings (warehouses, storage, workshop) divided into certain categories of premises, on the basis of certain characteristics of fire safety.
what to look for in determining fire safety category?
There are certain things that must be considered when determining the category of premises for fire safety:
1. The area of the building or premises.
2. Presence of flammable objects, their number and location.
3. The materials of which made the main cover (floor and walls), as well as other home furnishings.
4. The system of emergency safety (or lack of its availability and serviceability).
5. Description and characteristics of all stages of the process taking place in the building.
6. The height of the walls of the room.
main categories
So, what are the categories of premises?There are five, they are denoted by letters of the Russian alphabet from A to D. A - is an increased risk of explosion and fire, B - average risk of fire and explosion, B - average risk of fire, D - moderate fire hazard and D - low flammability.Now more about this and how it is assigned to rooms or that degree.
Category A. It is assigned to the premises where stored or treated in the process liquids, gases or materials that may catch fire and even explode under certain conditions (air temperature is below 28 degrees).
category space B. This category includes buildings that are stored or used special materials (dusts, powders, liquids, gases, objects) that can explode or ignite when the air temperature above 28 degrees.Such conditions are typically taking place, for example, in hot shops.
Categories buildings B1, B2, B3 and B4.The assignment of one degree or another important role played by certain factors and conditions.So, take into account the area of the building and features of its plan.Furthermore, the stored materials are studied: the number and the types.It is important to characterize and certain processes: their conditions, temperature stages.Evaluated and the nature and amount of fire load (flammable objects), their specific properties under the influence of various environmental conditions.
Category D (moderate fire risk) is assigned to the buildings in which is stored or treated in the processes of materials having high temperatures or under certain conditions, producing gases and sparks (eg during melting of metals or for welding).
The category D facilities include buildings in which there is storage and handling of materials and objects with low temperatures and normal flammability characteristics.Fire hazards in such buildings is minimal.
Conclusion In conclusion, we can write that is assigned to one or another category of fire inspector fire only after a detailed examination and study of the building.
