The fire extinguisher guide helps you choose the right extinguisher class for each room and hazard type. Using the wrong extinguisher can spread a fire or cause electrocution — fire extinguishers are rated by the class of fire they can safely fight.

If fire is not controlled within 15 seconds or grows — evacuate immediately and call 911.
Fire Extinguisher Selection and Placement Guide
The fire extinguisher guide covers all standard fire extinguisher classes (A through K) and helps you match the right extinguisher to each room and risk. An ABC multi-purpose dry chemical extinguisher handles most home emergencies, but specific hazards call for specific agents.
How Many Extinguishers Does a Home Need?
NFPA 10 recommends a 2A:10B:C rated extinguisher for every 3,000 sq ft of living space, with a maximum 75-foot travel distance. Practically: one on each floor, one in the kitchen, and one in the garage. Mount extinguishers near exits (not next to stoves/panels where a fire would block access) at 3.5-5 ft height.
Annual Inspection Requirements
Check the pressure gauge monthly — the needle should be in the green zone. Annual professional inspection is required by NFPA standards. Replace or recharge immediately after any discharge, even partial. Most dry chemical extinguishers last 6-12 years with proper maintenance; check the manufacturer's hydrostatic test date stamped on the cylinder.
FAQ
Is this fire extinguisher guide free?
Yes, completely free with no signup required. Get fire extinguisher class recommendations for any room or hazard.
What type of fire extinguisher should I have at home?
Every home should have at minimum one ABC multi-purpose extinguisher (rated for Class A, B, and C fires). Place one in the kitchen, one on each floor, and one in the garage. A 2.5 to 5 lb model is suitable for most home use.
What is a Class K fire extinguisher?
Class K extinguishers are designed for cooking oil and fat fires in commercial kitchens. They use a wet chemical agent that saponifies (soap-ifies) the burning fat, cooling it and preventing re-ignition. Home kitchens typically use ABC models, but a Class K or BC model is preferred for serious cooks.
How often should I inspect a fire extinguisher?
Inspect visually every month: check the pressure gauge is in the green zone, pin is intact, nozzle is clear, and there's no visible damage. Professional inspection is required annually. Replace or recharge after any use, or every 6-12 years depending on type.
Can I use water on an electrical fire?
Never use water (Class A) on electrical fires (Class C). Water conducts electricity and can cause electrocution. Use a Class C or ABC extinguisher which uses non-conductive agents like CO2 or dry chemical.
How do I use a fire extinguisher?
Remember PASS: Pull the pin, Aim at the base of the fire (not the flames), Squeeze the handle slowly, Sweep side to side at the base until the fire is out. Stay near an exit. If the fire is not out within 15 seconds or spreads, evacuate and call 911.
