Fire types are usually divided into six categories: A, B, C, D, E, and F, corresponding to solid matter fire, liquid or meltable solid matter fire, gas fire, metal fire, live equipment fire, and cooking fire in cooking utensils. Different types of fires require different types of extinguishing agents. Therefore, when selecting a dry powder extinguishing agent, make sure it is suitable for the target fire type.
2.Check the type of fire extinguishing agent: There are many types of dry powder fire extinguishing agent, including ABC dry powder, BC dry powder, etc. ABC dry powder extinguishing agent is suitable for Class A, B and C fires, while BC dry powder extinguishing agent is only suitable for Class B and C fires. Therefore, when selecting dry powder fire extinguishing agent, it is necessary to choose the appropriate type according to the type of fire.
3.Consider fire extinguishing effectiveness: Fire extinguishing effectiveness is an important indicator to measure the performance of fire extinguishing agents. When selecting dry powder fire extinguishing agent, attention should be paid to its fire extinguishing speed, fire extinguishing concentration and reignition after fire extinguishing. High quality dry powder fire extinguishing agent should have faster fire extinguishing speed, lower fire extinguishing concentration and lower reignition rate.
4.Consider safety: When selecting a dry powder fire extinguishing agent, ensure that it is harmless to the human body and the environment. Some dry powder fire extinguishing agents may contain harmful ingredients to the human body, so pay attention to protective measures when using. At the same time, it is necessary to ensure that the fire extinguishing agent will not cause pollution to the environment after use.
