What is the content of summer fire safety education? What are the A-level fireproof and thermal insulation materials?

In the case of forest combustibles and fire sources, whether a forest fire can occur mainly depends on the fire risk weather. Generally speaking, fire risk weather refers to the climatic conditions that are conducive to forest fires, such as high temperature, little precipitation, low relative humidity, strong winds, and long-term drought. So what is the content of summer fire safety education? What are the A-level fireproof and thermal insulation materials? Let's take a look at the introduction of Encyclopedia Knowledge Network!

What is the content of summer fire safety education?

Summer is hot and dry, which is the peak season for fires. To prevent fires in life, we must first pay attention to the use of electrical appliances. Most household fires are caused by improper use of fire and household appliances. Children should be taught not to play with fire or electrical appliances at home. Do not pull or connect wires randomly at home, and check power lines, power connectors and switches regularly. Secondly, be careful when using fire in life.

If a household appliance catches fire, do not pour water on it. Disconnect the power first, then use a dry powder fire extinguisher to put out the fire. In an emergency, you can use a wet towel or blanket to cover the appliance to put out the fire.

Be careful when using mosquito coils in the summer. The ignition temperature of mosquito coils is high, and they can easily ignite when they touch mosquito nets, clothes, etc. Therefore, be careful to place them in a safe place when using mosquito coils.

In the summer, when the temperature is high, cars parked outdoors are prone to fire. Pay attention to the daily maintenance and repair of the vehicle, and do not place lighters, air fresheners, mosquito repellents and other flammable and explosive items in the car that are easily flammable and explosive when heated.

What are Class A fireproof and thermal insulation materials?

Class A fireproof insulation materials are fireproof insulation materials with a fireproof grade of A. Class A insulation materials mainly include Class A1 materials and Class A2 materials. Class A fireproof insulation materials include foam glass boards, rock mineral wool boards, expanded perlite products, vitrified microbead products, etc.

Class A is non-combustible material, WW inorganic active wall insulation material, cement foam insulation board, rock wool board, glass wool board, foam ceramics, etc.

Grade B1 is flame-retardant material, mostly organic material, with a large amount of flame retardant added, such as polystyrene board, extruded board, phenolic board, polyurethane board, etc.

Grade B2 is flame retardant material, also known as flame retardant material, mostly organic thermal insulation material with an appropriate amount of flame retardant added.

Fire compartment division area

Single- and multi-story civil buildings: The maximum allowable building area for level one and level two fire compartments is 2,500 square meters, the allowable building height or number of floors for level three is 1,200 square meters for 5 floors, and the allowable building height or number of floors for level four is 600 square meters for 2 floors.

A fire partition refers to an area separated by fire walls, floor slabs, fire doors or fire shutters, which can confine the fire to a certain local area and prevent the spread of the fire. Of course, the partitions of the fire partitions also serve to isolate the smoke.
