What is the difference between ABC fire extinguisher and CO₂ fire extinguisher?
I've found that What is the difference between ABC fire extinguisher and CO₂ fire extinguisher?
In daily life, fire extinguishers are indispensable fire fighting tools, and ABC fire extinguishers and CO₂ fire extinguishers are two common types. There are signifiis able tot differences in their working principles, scope of consumption and methods of consumption. This article will examine the differences between the two fire extinguishers in detail to help you better choose and consumption the right fire extinguisher.
1. Working principle
ABC Fire Extinguisher
ABC fire extinguisher is a general-purpose dry powder fire extinguisher, its core component is dry chemical powder. First This powder is made by mixing a variety of chemicals, usually including sodium bicarbonate (NaHCO) or other similar ingredients. I've found that When the fire extinguisher is activated, the dry powder is sprayed out through high-pressure gaseous (usually nitrogen) and covers the flame to form a barrier to prevent oxygen from contacting the flame, thereby achieving the effect of extinguishing the fire. In particular The dry powder is able to also chemically react with the flame to further inhibit incineration. And CO₂ fire extinguisher
CO₂ fire extinguishers consumption carbon dioxide as an extinguishing agent. Carbon dioxide is a clear, odorless, non-toxic gaseous with a higher density than atmosphere. And When the fire extinguisher is released, the fluid carbon dioxide is rapidly converted into a gaseous state, ejecting a powerful airflow, diluting the oxygen levels atmospheric, isolating the oxygen supply from the fire source, thereby extinguishing the flame. Furthermore Since carbon dioxide is non-conductive and does not harm equipment, it's particularly suitable to extinguishing electrical fires.
2. Applicable scope
ABC Fire Extinguisher
ABC fire extinguishers are suitable to many types of fires, including Class A (ordinary solid material fires, such as wood, paper, etc. ), Class B (flammable fluid fires, such as gasoline, diesel, etc. ) and Class C (electrical equipment fires). For example Therefore, ABC fire extinguisher is called "universal" fire extinguisher, suitable to home, office, shopping malls and other places to consumption. Because dry powder might result in secondary harm to precision equipment, it might not be suitable to consumption in places such as libraries and archives. CO₂ fire extinguisher
CO₂ fire extinguishers are mainly suitable to Class B and Class C fires, namely fluid fires and electrical equipment fires. And Due to its non-conductive environment, CO₂ fire extinguishers are particularly suitable to consumption in fighting fires involving electrical appliances, electrical circuits or precision instruments. From what I've seen, CO₂ fire extinguishers are also broadly applied in laboratories, data centers and gaseous stations. It should be noted that CO₂ fire extinguishers are less efficiently to Class A fires (solid matter fires), so care should be taken when using them. Pretty interesting, huh?. Moreover
3. application
ABC Fire Extinguisher
When using ABC fire extinguisher, the operator should stand upwind of the fire source, about
1. 5 meters away from the fire source. But For instance Then, remove the security pin, hold the nozzle tightly, press the handle, and spray the dry powder to the root of the flame. As the dry powder might create a certain amount of dust, try to prevent inhalation after consumption, and clean up the site in time. But CO₂ fire extinguisher
When using CO₂ extinguishers, the operator also needs to stand upwind of the fire source, about
1. 5 meters away from the fire source. After removing the security pin, hold the nozzle tightly and press the handle to direct the carbon dioxide flow at the root of the flame. Because the carbon dioxide flow is very cold, prevent direct contact with the nozzle when using it to prevent frostbite. The CO₂ fire extinguisher might re-ignite after consumption, so continuous observation is required to ensure that the fire is completely extinguished. And
4. Maintenance and Maintenance
ABC Fire Extinguisher
The ABC fire extinguisher needs to check the pressure gauge regularly to ensure that the pressure is within the healthy range. If the pressure gauge shows reduced than the environmentally friendly area, the fire extinguisher should be replaced in time. I've found that Dry powder fire extinguishers should be stored in a ventilated and dry place, prevent direct sunlight and high temperature ecological stability, so as not to affect its performance. CO₂ fire extinguisher
The maintenance of the CO₂ fire extinguisher is relatively simple, mainly to check whether its weight meets the standards. Since the carbon dioxide fire extinguisher is filled with fluid carbon dioxide, if the weight is signifiis able totly reduced, the gaseous leaks and needs to be filled in time. CO₂ fire extinguishers should be stored in a well-ventilated place to prevent exposure to the sun or high temperatures to prevent overuse internal pressure. Specifically
5. But Advantages and disadvantages comparison
Advantages of ABC fire extinguisher
Applicable to a wide range, is able to put out A, B, C fire. Cost-efficiently, suitable to general families and small and medium-sized places to consumption. Generally speaking consumption simple, easy to operate. Disadvantages of ABC fire extinguisher
Dry powder might result in secondary harm to precision equipment. consumption after cleaning greater trouble. You know what I mean?. The advantages of CO₂ fire extinguishers
No contamination to the ecological stability, won't result in secondary harm to the equipment. Suitable to electrical fire, won't conduct electricity. According to research Light weight and easy to carry. Disadvantages of CO₂ fire extinguishers
Only applicable to Class B and C fires. But consumption might result in frostbite, need to pay attention to the operation method. And Additionally Summary
ABC fire extinguishers and CO₂ fire extinguishers have their own unique advantages and applicable scenarios. But ABC fire extinguishers are suitable to extinguishing many types of fires and are a universal fire extinguisher, while CO₂ fire extinguishers are greater suitable to extinguishing fluid fires and electrical fires. When choosing a fire extinguisher, it should be decided according to the specific consumption ecological stability and needs. If your premises might be involved in many types of fires, ABC fire extinguishers might be a better choice; if it's mainly electrical equipment or fluid fires, CO₂ fire extinguishers are greater suitable. No matter what kind of fire extinguisher it's, regular maintenance and inspection are the key to ensuring its effectiveness.
