ABC extinguishers (multi-purpose dry chemical) handle Class A (ordinary combustibles), Class B (flammable liquids), and Class C (electrical) fires, making them the standard home and office choice. BC extinguishers handle flammable liquids and electrical only; they do not work on paper, wood, or fabric fires.

Check the gauge monthly — the needle should be in the green zone. Disposable extinguishers typically last 8 to 12 years; rechargeable models can last longer with regular hydrostatic testing. Always follow the manufacturer's guidelines for your specific model. Replace your extinguisher if the shell is damaged, the gauge is in the red, or it has not been inspected within the recommended timeframe.

Yes for ABC-rated extinguishers. No for Class K (kitchen-specific wet chemical) extinguishers, which are designed for deep-fat fryer fires and should not be used on electrical fires.

Fire extinguishers range from 2.5 lbs for compact home models to 10 lbs or more for commercial units. Smaller 2.5 lb models are easier to handle and maneuver, while larger 10 lb models can be heavy and awkward for untrained users. Choose the lightest size adequate for the fire risk in your home or workspace.

No, one ABC-rated extinguisher works for both locations, but experts recommend one per area for fastest access. A Class K kitchen-specific extinguisher adds protection against deep-fryer fires in homes with heavy cooking.

Ventilate the area, clean up the dry chemical residue (its' corrosive to metal), and replace or recharge the extinguisher immediately. Do not assume a partially used extinguisher is ready for the next fire.

Fire extinguishers should be visually inspected monthly and professionally inspected once a year. Hydrostatic testing is required every 5 to 12 years depending on the type, and extinguishers should be recharged after any discharge, even partial. For workplaces, keeping inspection tags current is required for compliance.
