According to the fire of different substances, fires are broadly divided into four types.

• Class A fires for solid combustible materials, including wood, fabric, paper, rubber, and plastic.

• Class B fires are flammable combustible liquids, flammable gases, and grease fires.

• Class C fires are fires in energized electrical equipment.

• Class D fires are partially combustible metals, such as magnesium, sodium, potassium, and their alloys.

According to the fire, extinguisher logo to choose

General fire extinguishers are marked with the type and level of fire extinguishing label. For example, A, B, etc., the user will be able to immediately identify the fire extinguisher that is suitable for fighting which type of fire. At present, the commonly used fire extinguishers are various specifications of foam fire extinguishers, various specifications of dry powder fire extinguishers, carbon dioxide fire extinguishers, halogenated (1211) fire extinguishers, etc. Foam fire extinguishers can generally put out A, B fire, when the electrical fire, the power was cut off, you can also use the foam fire extinguisher to put out. Dry powder fire extinguishers and carbon dioxide fire extinguishers are used to put out B, C fires. Combustible metal fires can be extinguished using dry powder extinguishers for Class D fires. Halogenated (1211) fire extinguishers are mainly used to put out flammable liquids, electrically charged electrical equipment, and precision instruments, as well as fires in the engine room, this fire extinguisher contains no corrosive agent, does not leave traces after extinguishing the fire, the effect is also better.

Notes on the use of fire extinguishers to extinguish fires

General portable fire extinguishers with the spraying time of its contents within a minute, the actual effective extinguishing time of only 10 to 20 seconds, in the actual use of the process, you must correctly grasp the use of methods, otherwise not only cannot extinguish the fire but also delayed the time to extinguish the fire. It must be noted that after a fire, the use of fire extinguishers to put out the initial fire in a timely manner, is to avoid the spread of fire, expanding and causing greater damage to the powerful measures.

In addition, the fire department also reminded that once the fire is found, should also be immediate to the fire department in a timely manner, do not count on the fire extinguisher to extinguish the fire and not to the fire department, because the fire extinguisher is limited in area and capacity, can only adapt to put out the incipient fire. After the fire occurs, the general spread is relatively fast, delayed alarm time, delayed firefighting opportunities, will inevitably cause greater losses.
