Hangzhou Fire Protection Reminder: Fire extinguishers must be provided for rented houses, and it is also recommended for self owned houses

As for why there is a fire extinguisher at home, Zhang Dandan said that he is engaged in real estate related work, so he knew that renting a house should be equipped with a fire extinguisher, so he also had one at home. " Just in case, I didn't expect to use it this time. “

This morning, Hangzhou Yuhang Fire Rescue Brigade presented Zhang Dandan with a fire protection package containing two water-based fire extinguishers. "Her fire extinguisher was used in the fire, so we will send her two more." The firemen said.

Netizens also discussed the topic of "facial mask heroines" who always have fire extinguishers at home. "Do you have to equip a fire extinguisher at home?" "There are so many kinds of fire extinguishers on the market, what kind of fire extinguisher is better to keep at home?"

Shen Tu, Deputy Chief of Yuhang Fire Rescue Brigade, Shi Lei explained this——

According to Article 16 of the Several Provisions of Hangzhou on the Safety Management of Residential House Rental, the lessor of the residential house is the first person responsible for fire safety and is responsible for the fire safety of the residential house. Among the fire safety requirements that the residential house should meet, the lessor of the residential house shall equip each lessee with masks, alarm whistles, flashlights and other facilities, and shall equip at least one fire extinguisher according to the standard, The extinguisher shall be ammonium phosphate (ABC) dry powder extinguisher of more than 3 kg or corresponding quantity.

"That is to say, fire extinguishers must be equipped in the rental house." Shen Tu and Shi Lei said.

However, there are no specific laws and regulations at present, and fire fighting facilities such as fire extinguishers must be equipped in the self owned housing. "But we have been urging everyone to prepare basic fire-fighting equipment such as fire extinguishers and smoke masks at home, and to know the location of fire-fighting facilities in their own communities in case of emergencies."

What kind of fire extinguisher should be equipped in residents' homes? The hour news specially interviewed the firefighters, and they were all sorted out——

Fire rescue personnel said that the common types of fire extinguishers include dry powder extinguisher, water-based extinguisher and gas (CO) extinguisher.

"Different types of fire extinguishers have different fire extinguishing principles and use scenarios." The fire rescue personnel said that the fire extinguishing principle of the dry powder extinguisher is to use the volatile decomposition products of inorganic salts in the dry powder to react to produce chemical suppression to extinguish the fire, or rely on the dry powder falling on the surface of combustibles to isolate oxygen to extinguish the fire; The water-based fire extinguisher can rapidly reduce the temperature of the fire site and inhibit the thermal radiation by evaporating a large amount of heat from the fire site with the sprayed water mist. At the same time, the surfactant in the water mist can quickly form a dual role of isolating oxygen, cooling and isolation on the surface of combustibles, so as to achieve the goal of rapid fire extinguishing; The gas (CO) type extinguisher is vaporized when the liquid carbon dioxide is ejected, which can absorb a lot of heat, reduce the temperature of the fire site and combustor, and make the combustion impossible. In addition, carbon dioxide does not support combustion, which can isolate air and suffocate the flame.

Among the three common fire extinguishers, the dry powder extinguisher has the lowest use cost and is suitable for solid, liquid, gas, electrical and kitchen oil fires. However, the dry powder of the dry powder extinguisher may cause certain pollution and it is troublesome to clean up after extinguishing; Water based fire extinguishers are suitable for solid, liquid and other fires, and can also be used for electrical fires below 220 volts after technology improvement. At the same time, water-based extinguishers are less polluting and environmentally friendly after use, but they are more expensive than dry powder extinguishers; Gas (CO) extinguishers are commonly used for the initial fire of household books, archives, valuable equipment, precision instruments, electrical equipment below 600V and oil. When using the gas (CO) extinguisher, there is almost no residue left, but CO may cause asphyxia, etc., so it is better to use it after training.

"We recommend to equip dry powder fire extinguishers or water-based fire extinguishers at home. As for the number of fire extinguishers, at least 2 are recommended." Fire rescue workers said that fire extinguishers can generally be placed at the entrance, kitchen and bedroom area.
