How to Safely Extinguish Small Fires
When a fire first catches, it may be small enough that you can put it out with a fire blanket or fire extinguisher. However, if the fire is spreading quickly, then it is important to leave the scene immediately and call 911.
If you have an electrical fire, the first step that is important to take is to cut the power to the system. Cut it off at the breaker rather than turning off the wall switch. Don’t try to pull the plug out of an appliance. There may be an electrocution hazard.
You need to use a Class C extinguisher to put out an electrical fire if you cannot cut the power to the source. Use a Class A or dry chemical extinguisher if you have cut the power. Alternatively, you can use a fire blanket to smother the flames if you were able to cut the power.
For fires involving flammable liquids, you should first turn the fuel supply off. Then use a fire blanket to smother the flames. As with electrical fires, water-based extinguishers should not be used. Use a Class B extinguisher instead.
