What fire extinguishers do you have at home? Is the fire door qualified?

author: from: time:2022-12-05

Fire extinguishers, fire doors, fire hoses... These are all fire products to protect the lives and property of citizens. However, with the growing sales channels of these products, some fake and inferior products emerge in endlessly.

What does a qualified fire door look like inside? The real code can be checked

Dry powder, water-based and gas (carbon dioxide) extinguishers, which one is suitable for household use

With the temperature getting warmer, it entered the high incidence period of fire in spring. Residential areas, centralized charging points for battery cars and other fires occur frequently. At the beginning of the fire, what can citizens do?

"As long as any fire occurs, the first thing is to call the '119' alarm. At the same time, you can evaluate the fire situation and decide whether to save yourself or escape." Firefighters suggested that in the case of a small fire, citizens could try to put out the fire by themselves while ensuring their own safety.

Citizens should extinguish their own fires, and fire extinguishers are the most important tools. At present, the mainstream types of fire extinguishers on the market are dry powder extinguisher, water-based extinguisher and gas (carbon dioxide) extinguisher.

In the experiment, the fireman simulated the battery fire of the battery car. After the battery of the battery car catches fire, the flame presents a jet shape and burns rapidly and violently.

The firefighters successively used dry powder extinguisher, water-based extinguisher and gas (carbon dioxide) extinguisher to extinguish the fire.

The use of dry powder fire extinguisher has little effect on the battery fire, and the battery will re ignite after being covered with dry powder for a short time.

Subsequently, firefighters use gas (carbon dioxide) extinguishers to extinguish the fire. When the extinguisher sprays gas (carbon dioxide), the flame will be suppressed instantly, but the battery will re ignite after the extinguisher is removed.

Finally, firefighters used water-based extinguishers to extinguish the fire. Although the fire was still not completely extinguished, the fire weakened after use.

"The biggest feature of the battery fire is that the battery is constantly reacting inside, causing the fire to re ignite." Firefighters said that the best way to put out the fire of the battery car is to use a large amount of water to impact the fire area, cool down the fire location and prevent the reaction from continuing.

"Although none of the three types of fire extinguishers can completely extinguish the battery car fire, it is obviously felt that the fire extinguisher can still work." Firefighters said that it is generally recommended to equip dry powder or water-based fire extinguishers at home. "The cost of dry powder extinguishers is lower, while that of water-based extinguishers is higher."
