Exchanging Your Extinguisher: Do You Need a New One?

Fire extinguishers are essential tools for fire safety, but an alarming number of households don’t know when they need a replacement. If a fire breaks out in your home and you have a non-operational fire extinguisher, you are far more likely to face injury or property damage.

By understanding how to read, operate and replace your fire extinguisher, you can stay vigilant, prioritize safety and avoid the worst case scenario if you do experience a house fire.

What Do the Symbols on a Fire Extinguisher Indicate?

Only 43% of Americans own a fire extinguisher, and even fewer know how to read the symbols on the outside of the can. Here is a basic rundown so you can assess what you have in your home or find the right extinguisher. 

1. Class Symbols: Fire extinguishers are classified based on the type of fire they can extinguish. The symbols depict the class of fire the extinguisher is designed for, such as Class A (ordinary combustibles like wood or paper), Class B (flammable liquids), Class C (electrical fires), Class D (combustible metals) and Class K (kitchen fires).
2. Pressure Indicator: Fire extinguishers often have a gauge that indicates the internal pressure level. The gauge should be in the green zone, showing that the extinguisher is properly pressurized and ready for use. 
3. Expiration Date: Fire extinguishers have a limited lifespan – around 5-15 years, depending on the type and manufacturer. Look for a date stamp or label with the expiration date. If the extinguisher is past this date, it should be replaced.

Signs It’s Time to Replace Your Fire Extinguisher

Fire extinguishers do have a shelf life, but they occasionally need to be replaced before their expiration date. Consider the following when deciding if you should replace yours:

1. Physical Damage: Inspect your fire extinguisher regularly for any visible signs of damage, such as dents, rust, leaks or a broken nozzle. Physical damage can impair the functionality of the extinguisher and even render it ineffective during an emergency. If you notice any damage, replace the extinguisher right away.
2. Discharged or Low Pressure: If you have used your fire extinguisher in the past, it may need recharging or replacement. A discharged extinguisher or one with low pressure will not perform effectively. Check the pressure gauge often, and if it shows no pressure or is in the red zone, it’s time to recharge or replace.
3. Inadequate Maintenance: Fire extinguishers need periodic maintenance so that they work consistently. If you have neglected routine maintenance, such as inspections, recharge or hydrostatic testing, it’s crucial to replace the extinguisher so you know it will function correctly during an emergency.
