Questions about our fire safety tools
For most homes, a multi-purpose ABC dry chemical extinguisher covers ordinary solids, flammable liquids and electrical hazards. For kitchens with a deep fat fryer, add a wet chemical (Class K/F) extinguisher. The NFPA recommends at least one extinguisher per floor, stored in an accessible location.
No. Every tool on this site — the extinguisher finder, escape plan builder, smoke alarm checker — runs entirely in your browser. Nothing you enter is sent to a server. Checklist ticks are stored in your browser's localStorage and never leave your device.
The letter systems are not the same. US Class C is energised electrical; EU/UK Class C is flammable gases. US Class K is cooking oils; EU/UK Class F is the equivalent. Using the wrong extinguisher can make a fire worse. Our fire classes table shows the full comparison. Primary sources: NFPA 10 and BS EN 2 / EN 3.
Do not attempt to fight a fire if: the fire is larger than a waste-paper basket, the room is filling with smoke, you do not have a clear exit behind you, or you are unsure of the fire class. In all these cases, evacuate immediately and call your emergency number. The American Red Cross and UK HSE both emphasise evacuation over fire-fighting for untrained individuals.
