Property fire safety knowledge training content

The contents of property fire safety knowledge training include: the basic knowledge of combustion, the types of combustion, the conditions and prevention of fire, the types of fire and the selection of fire extinguishing equipment for various fires.

1, basic knowledge of combustion.

Combustion, commonly known as fire, refers to the chemical reaction of combustible substances with oxygen or oxidant to release heat, usually accompanied by flame and smoke. A disaster caused by burning out of control in time or space is called a fire. When any substance burns, there is a process from an unburned state to a burned state. There are three necessary conditions in this process, namely, combustible, combustion-supporting substance and ignition source, which must interact with each other.

Combustible materials that can react with oxygen or other oxidants in the air are called combustible materials. Combustion-supporting substances can help and support the combustion of combustible substances, that is, substances that can undergo oxidation reaction with combustible substances are called combustion-supporting substances. Ignition source, any energy that can cause combustion reaction between combustible substances and combustion-supporting substances, is called ignition source.

2, the type of combustion and fire conditions and prevention.

The types of combustion can be divided into flash, fire, spontaneous combustion, explosion and so on. The condition of fire formation is that there must be fire source, combustible and combustion-supporting materials. Fire prevention is to eliminate the conditions of combustion, and destroy the conditions of combustion by controlling combustible materials, isolating combustion-supporting materials and eliminating fire sources.

In addition to doing a good job in fire prevention from the material and objective environment, it is more important to strengthen people's subjective awareness of fire prevention and disaster prevention. Only by letting people know and pay attention to fire prevention can they consciously abide by various fire prevention rules and regulations, put an end to fire sources and take necessary fire prevention measures. Only in this way can we really eliminate the conditions of fire.

3, the types of fire and all kinds of fire fighting equipment.

The burning phenomenon that is out of control and causes damage to property and people is called fire. According to the nature of combustion, it is divided into five kinds of fires, and the fire extinguishers suitable for all kinds of fires are as follows.

Class A refers to solid fire containing carbon. At this time, clean water fire extinguisher, foam extinguisher and ammonium phosphate dry powder fire extinguisher (ABC dry powder fire extinguisher) can be selected. Class B refers to flammable liquid fire. At this time, you can choose dry powder fire extinguisher (ABC dry powder fire extinguisher) and carbon oxide fire extinguisher. Foam extinguisher is only applicable to oil fires, not polar solvent fires. Class C refers to combustible gas fire. At this time, you can choose dry powder fire extinguisher (ABC dry powder fire extinguisher) and carbon dioxide fire extinguisher.
