Make sure you read and understand the instructions on your fire extinguisher before you need it.
Most household fire extinguishers have a gauge to indicate whether the unit is full and what to do if it isn't (refill, discard).

A fire extinguisher is an apparatus, usually containing chemicals, for putting out a fire. It extinguishes a fire by excluding oxygen so that combustion can no longer continue. The extinguisher must deliver a powerful spray of water, foam, or powder to smother the whole fire as quickly as possible, so its contents are pressurized. Some extinguishers produce a jet of carbon dioxide, a heavy gas that prevents burning.
Here's how to use the most common type of household fire extinguishers:
- Pull the pin near the top of the extinguisher.
- Approximately 6 feet away from the fire, aim the nozzle at the base of the fire.
- Press the trigger and move the spray from side to side to smother the entire fire.
- Continue spraying until the fire is completely out. Use a second fire extinguisher if necessary.
- Don't reuse without recharging the extinguisher following the manufacturer's instructions, or replacing the unit.
