A common size extinguisher for homes is rated (2A:10B:C). Extinguishers should be installed above the reach of children, away from sources of heat, and near an escape route.
The best kind of extinguisher for maximum coverage in a house is ABC dry powder. Get at least a 5 pound size, and make sure it is all metal construction (ie Amerex or Ansul brands).
For a room of average dimension, a 5-lb fire extinguisher may be sufficient. For larger commercial spaces and warehouses where a fire has more room to spread, a larger 10-lb model may be necessary.
An ABC dry chemical extinguisher is the best option for nearly all homes and for use by a lay person. You can buy one at Lowe's, Home Depot, and various hardware stores very easily.
Even though the ABC fire extinguisher may be able to temporarily put out the cooking fire, the class K fire extinguisher with it's wet chemical agent will help make sure it does not reignite.
Always look for the “UL Listed” or “ULC Listed” label on a fire extinguisher to ensure it is certified for use by a nationally recognized testing laboratory. Fire extinguishers vary in size and weight, but it is recommended to select the largest fire extinguisher that a user can safely and comfortably operate.
While ABC extinguishers are versatile and can combat a wide range of fires, CO2 extinguishers are specifically designed for electrical and flammable liquid fires. The choice between the two depends on the specific needs of the environment and the types of hazards one may encounter.
Fire extinguishers are required in most commercial, industrial and residential buildings. The only buildings where fire extinguishers are not mandated are family homes.
A 10-pound to 20-pound dry chemical fire extinguisher will last anywhere from 10 to 25 seconds. Again, this depends on the model and the weight you are using.
Class F wet chemical fire extinguishers are designed for kitchen fires that occur in both domestic and commercial kitchens. They are very effective in putting out both grease fires and oil fires through the process of saponification.
On average, you can anticipate a recharge to cost between $25 to $50. However, this range can fluctuate based on the size and type of extinguisher. For instance, with specialized technology like Halotron, it is pricier than your standard 10lb ABC extinguisher.
The kitchen and garage are good sites for an extinguisher. However, do not place an extinguisher over the stove or buried in storage in the garage, but rather hang it on the wall no less than 4 inches or greater than 5 feet from the ground.
When do fire extinguishers expire? Although they don't have a true "expiration date," traditional fire extinguishers generally have a 10-12 year life expectancy. Disposable (non-rechargeable) fire extinguishers should be replaced every 10 years.
Other ways to put out grease fires…
Use a class B or BC or ABC fire extinguisher. A Fire Extinguisher will release a-lot of pressure, so start at a distance away and move towards the fire, rather than up-close spraying directly on to the burning grease which could tip the pan and spread the fire.
Homes: There's no reason you can't keep a 2kg CO2 fire extinguisher in your home. However, because so many home fires are started by cooking oil in the kitchen, it's not a favourite among homeowners. That being said, a CO2 extinguisher can still be used in any other part of the house, including the garage.
It's important to note that while ABC extinguishers are versatile, they are not suitable for fires involving cooking oils and fats (Class K fire extinguishers are suited for this) or combustible metals.
Difference between foam and powder
Powder extinguishers contain a fine powder that forms a layer over the flames and smothers them. A foam extinguisher contains water-based foam that smothers and cools the fire. Foam and powder are generally considered to be equally effective at extinguishing fires.
The fire rating is found by multiplying the floor area in metres squared (m²) by 0.065. Therefore for a floor area of 200m² the fire rating is 200 x 0.065 = 13A. A 9 litre water extinguisher has a fire rating of 13A, therefore one 9 litre water extinguisher will be required for every 200m² of floor area.
Should you buy a fire extinguisher? Yes, provided you know when and how to use it. Fire extinguishers can be a small but important part of the home fire safety plan. They can save lives and property by putting out a small fire or suppressing it until the fire department arrives.
Powder fire extinguishers are the most often recommended home fire extinguishers. These fire extinguishers spray a chemical-based powder that efficiently douses flames and puts out the fire's source. Powder fire extinguishers are also called ABC extinguishers because they can be used in fire classes A, B, and C.
The National Fire Protection Association (NFPA) provides minimum recommendations for the home: Primary Fire Extinguishers - For your main home protection, install a 2-A:10-B:C rated extinguisher on every level of your home - no more than 40 feet apart. Include all locations where a fire may start.
In some cases, installing low-cost safety features and security upgrades such as alarms and fire extinguishers can translate into a reduced home insurance premium.
Recharging is generally more economical for larger, well-maintained extinguishers. However, replacing a small or damaged extinguisher might be more cost-effective in the long run, especially if frequent recharging is required.
