Information

Although there are not many types of fire extinguishers, the various parameters are still dazzling.


Various parameters of the fire extinguisher


Capacity: Dry powder fire extinguishers are usually expressed in kg, common ones are 520g, 600g, 1kg, 2kg, 3kg, 4kg, 8kg, etc. Water-based fire extinguishers are expressed in ml, and the common ones are 500ml, 900ml, 950ml, 1L, 2L, etc.


Extinguishing level: Extinguishing level indicates how much fire this fire extinguisher can extinguish.


0.5A8B5F means that this fire extinguisher can extinguish 0.5 units of Class A fires, 8 units of Class B fires or 5 units of Class F fires. The larger the value, the stronger the ability to extinguish this type of fire.


Spray distance and spray time: The spray distance is mainly related to the pressure, and the spray time is mainly related to the amount of filling. Generally speaking, the spray distance is between 2-3 meters, and the spray time is at least 5 seconds.


Whether it can extinguish electric fire: Electric fire is Class E electric fire. In fact, dry powder fire extinguishers and most water-based fire extinguishers can extinguish electric fires, but remember to cut off the power first if you can cut off the power. If not, be sure to maintain the maximum effective distance to spray.


Working temperature: The dry powder fire extinguisher can basically withstand the working temperature of -20 ℃ ~ 55 ℃, and it is suitable for the home environment and the environment on the car. Water-based fire extinguishers, the normal temperature is 0 ℃ ~ 55 ℃, there is no problem in the south, but if the north is used in winter, the temperature is too low, you have to buy low-temperature water-based fire extinguishers, which can withstand the temperature of minus 20 ℃.


Material of cans, nozzles and handles: At present, the cans of fire extinguishers mainly include carbon steel, aluminum and stainless steel. Their quality and price from low to high are: aluminum < carbon steel < stainless steel. Aluminum is too soft and easy to explode; carbon steel will rust; stainless steel has no disadvantages, except that it is expensive. When purchasing, you need to consider the use environment of the fire extinguisher, and try to choose stainless steel.


In general, the most important thing to buy a fire extinguisher is to look at its fire extinguishing level, the place where it is used, and then take into account the working temperature and whether it can extinguish an electric fire. Then purchase different quantities of fire extinguishers according to the size of the use environment.
