According to a fire loss study done by the National Fire Protection Association, house fires accounted for 75% of all structural fires in the United States. There are about 400,000 residential property fires in the U.S. each year, and these residential fires account for more than 3,700 human fatalities each year. Even when all other natural disasters are combined, fires still typically claim more American lives per year.
Considering the cost, frequency, and loss of life related to residential fires, it’s important for homeowners to have loss control measures in place. A fire extinguisher might seem like a simple item, but when properly selected, placed, and maintained, a fire extinguisher can be a powerful tool to prevent widespread fire loss. The best thing is that a fire extinguisher is a relatively cheap investment, as prices start at around $20.00. It’s important to become familiar with the different classes of fire extinguishers. There are five classes, with each class based on what type of fire the extinguisher is capable of extinguishing. The five extinguisher classes are marked with a class specific color, geometric symbol, and/or picture.

Fire Extinguisher Tips
- Fire extinguishers are important fire protection tools. However, it’s vital to know the fire type and extinguisher class before attempting usage. Using the wrong extinguisher on the wrong fire can make the fire worse and cause life threatening injury.
- It’s extremely important for all members of the household, babysitters, housekeepers, and any other potential user to know how to safely and correctly use the fire extinguisher. Since most will not be using an extinguisher on a regular basis, it’s also important to periodically review the instructions.
- Because fires might often involve a combination of elements, most fire protection experts recommend a fire extinguisher with an ABC rating.
- Fire protection experts recommend that a medium-sized fire extinguisher be placed in the kitchen and garage. A fire extinguisher should also be placed on each additional floor of the home.
- All fire extinguishers should be inspected annually and maintained by a professional fire equipment supplier. If not properly maintained, a fire extinguisher might not discharge when needed. There’s also the risk of it rupturing when pressurized, which can result in serious injury.
- Having fire extinguishers in the home might reduce the cost of home insurance. Contact the insurance broker for the home to find out if a discount for fire loss prevention measures is offered.
Keep in mind that fire extinguishers are vital protection against fire loss, but they must be properly selected, placed, and maintained.
