If there's a fire, should you evacuate or fight the fire with an extinguisher? Know when to fight and when to go.
When to use a fire extinguisher
Fire extinguishers are designed to contain or put out a small fire until the fire department can arrive. They are not designed for use on large or spreading fires.
Before you fight any fire, make sure that:
- You know how to use the fire extinguisher
- Everyone else has left the building and someone is calling 9-1-1
- The fire is small, confined and not spreading
- You have a clear escape route
- You have the right type of extinguisher for the type of fire that is burning
Types of extinguishers
No single fire extinguisher can be used safely and effectively for every type of fire. Some contain chemicals that will not work in certain situations and can even cause harm.
Extinguishers are labeled with symbols or letters for the classes of fire they can put out. Classes are based on what types of combustible materials are in a room. Learn the different classes of fire and check the contents of a room before buying an extinguisher for it.
| Dry chemical extinguishers |
|
There are two types of fire extinguishers that use a dry chemical:
|
| Carbon dioxide extinguishers |
| These extinguishers contain liquid CO2 that is discharged as a gas. They are effective on B and C class fires. CO2 does not leave a harmful residue and is environmentally friendly. It is also safe to use around electronics. |
| Water extinguishers |
| These extinguishers are suited for A class fires only. In B class fires, the water will spread the flames. In a C class fire, the water is conductive and poses a risk of electric shock to the operator. |
Choosing an extinguisher
All fire extinguishers must be:
- Rated for the type of fire they can extinguish
- Large enough to handle the fire
- In working condition and fully charged
- Accessible
- Used by a properly trained person
How to use
To use an extinguisher, remember the acronym PASS:
- Pull the pin or other lever that unlocks the operating
- Aim low at the base of the fire
- Squeeze the lever or button above the handle to discharge the extinguishing agent
- Sweep the nozzle or hose from side to side
Always read the instructions that come with a fire extinguisher and learn how to use it before a fire happens.
