6 steps to choose an effective home fire extinguisher
A portable fire extinguisher is an important safety item that every home and vehicle should have ✔️ ✅ When used correctly, it can reduce or even prevent a disaster caused by a fire ✔️ ✅ Choosing one is simple once you understand the different types of fire extinguishers available for different types of fires that can occur
Even in homes or other buildings with automatic fire suppression systems, portable fire extinguishers add an extra layer of fire protection to be used when occupied. They are required in all types of buildings other than one- or two-family homes.

2.Learn how to classify fires in the house.
Decide what types of fires are likely to occur in that location and choose the right type of fire extinguisher. There are 5 classifications.
A - Common combustibles such as paper and wood.
B - Flammable liquids and fumes such as gasoline and molten plastic.
C - Electrical fires include any energized electrical object.
D - Flammable metals such as magnesium wheels or lithium batteries.
K - Deep oil and grease found in kitchen fires.

3. Choose a fire extinguisher that meets fire extinguisher standards.
For use on all types of fires you may encounter. Some kind of fire extinguisher Can be used for many types of fires; others can actually be dangerous when used on multiple specific classes. All fire extinguishing agents have the effect of cooling or extinguishing a fire, or otherwise disrupting the chain of chemical reactions we call ''fire''.
- Fire extinguishers typically contain one or more solid or liquid chemicals for extinguishing fires and another chemical gas as a propellant, or, in some cases, the gaseous propellant is also a gaseous fire extinguishing agent, e.g. like CO2. Types of fire extinguishers include: water (with or without anti-freeze), water foam, dry chemical (as well as dry powder), wet chemical, carbon dioxide (CO2) and ''clean agents'', such as such as Halon® and similar chemicals cool and extinguish the fire and then quickly evaporate. - For example, a water-type fire extinguisher should only be labeled for use on Class A fires and not on B, C, D or K fires, as they may be aggravated by water.
- If you absolutely need a dry powder fire extinguisher for class D fire metal hazards, be sure to get advice to avoid choosing one that may not be effective for your particular purpose.
- Many types of fire extinguishers can be used for many types of fires, the most common being ABC. This shows a rating for use on class A, B or C fires. While they may have wide applicability, they can create a mess, which means a different may be more appropriate. For example, a CO2 or ''clean agent'' fire extinguisher may be a better choice for fires involving expensive electronics or machinery.
- When a fire extinguisher has a capacity greater than the minimum, the label will have a number indicating the rating for each classification, such as 2-A, 10-B. The higher the number, the more the fire will be extinguished, at least under perfect conditions. For example, a 10B rating indicates the ability to create a 10-foot-square pool of fiery liquid. This is good to know, if you only have one 10B fire extinguisher and one 30B fire. Types C, D and K are not required to have any additional numbers.

4.Nhận biết rủi ro khi chọn sai loại bình chữa cháy.
- A CO2 fire extinguisher produces a jet of gas at over 100 degrees below zero. In case of misuse, this can cause immediate and serious injury. CO2 and many ''clean agents'' are also asphyxiants that can expel air (and its oxygen) from an enclosed space, making it impossible for humans and animals to breathe.
- Do not place multi-purpose ABC fire extinguishers near oxidizing agents such as swimming pool chemicals. Only Class A water fire extinguishers should be used there.
- Where a Class K fire extinguisher is installed, occupants should be aware that the extinguisher is intended for fryer fires and not waste basket fires.
- A CO2 fire extinguisher can be used outdoors, but you should know that its effects can literally blow away and a fire can quickly flare up again when you run out of CO2.

5. Choose a fire extinguisher of the appropriate size.
- Consider where we place fire extinguishers, use them according to the scale and needs of the location. For example, you may want a larger fire extinguisher in a garage that holds a large volume of combustibles, while a smaller extinguisher may be appropriate for use on a small cooking fire. Remember that children may have difficulty using heavier fire extinguishers.
- Instead of having one large fire extinguisher, consider using several smaller ones. That way, not only can you have a wider choice of types (if you choose), you can have a better chance of one of them actually working, when put to use in the event urgent.

6. Long-term maintenance and replacement plan for fire extinguishers.
You need to check it periodically (at least once a year) then maintain or replace it if necessary. Ensure technical specifications and safety when used.

- Once you have chosen fire extinguisher appropriate, install and maintain it as if your life might depend on it someday.
- Make sure to place it in an easily accessible and preferably visible location and that everyone in the house knows how to operate it properly. You may also want to hang a sign or label to show guests where the fire extinguishers are located, in case you're not there when they need them.
- It is also important to read and understand the necessary inspection, testing and maintenance steps for your fire extinguisher. Failure to maintain your fire extinguisher can result in the fire extinguisher not working when you need it most.
