Our first instinct on hearing a smoke alarm is to locate the cause of the smoke and douse a flaming or smoldering fire. A CO2 fire extinguisher is, therefore, a piece of crucial safety equipment for every household.
Carbon Dioxide fire extinguishers contain non-flammable, pure carbon dioxide gas. They are typically suitable for Class B (flammable liquids and gases) and Class C fires (electrical fires).
However, it can be used to tackle other classes of fire too. There are six different classes of fire.
Classes of Fire
- Class A – wood, paper, textile
- Class B – flammable liquids such as petrol, diesel, or oils
- Class C – flammable gases like propane, butane, methane, etc.
- Class D – electrical apparatus, computers, phones, etc.
- Class E- cooking oils and fats
CO2 Fire Extinguisher Uses & Safety Tips
Portable fire extinguishers are used to douse the fire that is confined to a small area or to control the spread of fire. If you see the fire is spreading, always call the fire department for help.
Here are some tips to help you handle CO2 extinguishers safely.
1. Careful Usage: Follow the PASS (Pull, Aim, Squeeze, Sweep) method when using the fire extinguisher.
- Pull the pin
- Aim low
- Squeeze the lever slowly
- Sweep the nozzle from side to side
2. Place them near an exit
Keeping it near the exit has several benefits. Everyone can access it and remember its location. Also, one always runs towards an exit to escape a fire. Placing it at an exit means that you wouldn’t have to stay inside a building and go looking for it.
3. Check the pressure
The pressure should be optimum to fight a fire. Therefore, always check the pressure gauge of the fire extinguisher before using it. CO2 fire extinguishers do not have a pressure gauge and the liquified CO2 is always on a pressure of 55 bar at room temperature.
4. Read the manual carefully
Always read the guidelines on the usage of a fire extinguisher in the manual provided by the manufacturer.
