Understand fire.
Stay ahead of it.
A growing guide to how fire behaves, how to prevent it at home and at work, and what to do when it starts — with plain-language guides, working tools and clear visual explainers. Content references guidance from NFPA, USFA and UK MHCLG.
Cool it
Heat
The energy that raises fuel to its ignition temperature. Remove it — by cooling with water — and the fire stops.
In a real fire, get out first and call your local emergency number. This site is for learning and preparation — it never replaces emergency services.

How a room fire grows
A compartment fire typically moves through four stages. The window for escape and for using an extinguisher is in the first two — once flashover happens, the room is no longer survivable.
- Incipient — ignition; small, often smouldering.
- Growth — flames spread; hot smoke layer builds.
- Fully developed — after flashover; all fuel burning.
- Decay — fuel or oxygen runs out.

Ordinary solids
Use
Never use
Aim at the base of the flames and sweep side to side. Watch for re-ignition — soak smouldering material.
Always follow the label on your extinguisher and get trained before using one.

Glossary
Words worth knowing
- Assembly point
- A safe, agreed place outside a building where everyone gathers after evacuating, so people can be counted.
- Backdraft
- A sudden burst of fire when air reaches an oxygen-starved, superheated space. The supply of oxygen causes rapid re-ignition.
- Breathing apparatus
- The air-supply kit firefighters carry to let them operate in smoke-filled spaces they cannot otherwise breathe in.
- CO₂ extinguisher
- An extinguisher that uses carbon dioxide gas to smother a fire by displacing oxygen. Leaves no residue; rated for Class B and electrical hazards.
FAQ
Common fire-safety questions
No. FireTheGuide is an independent educational resource that summarises publicly available guidance from official bodies such as the National Fire Protection Association (NFPA), FEMA / USFA, and UK MHCLG. Always follow your local fire code and the instructions on your equipment.
Get out immediately — do not collect belongings. Close doors behind you to slow fire spread. Once outside, call your local emergency number (911 in the US, 999 in the UK, 112 in Europe). Never re-enter a burning building.
See our emergency quick-reference page for region-specific numbers.
According to USFA data, cooking is the leading cause of home fires in the US, accounting for nearly half of all incidents. Heating equipment, electrical faults, smoking materials and candles follow. In the UK, Home Office fire statistics show a similar pattern, with cooking fires most frequent.
Yes. The NFPA 72 standard recommends smoke alarms inside every bedroom, outside sleeping areas and on every level of the home. In the UK, The Smoke and Carbon Monoxide Alarm Regulations 2015 require alarms on every floor. Test monthly, replace batteries annually, replace the unit every 10 years.
Pull the pin. Aim at the base of the fire. Squeeze the handle slowly. Sweep side to side. Only use an extinguisher if the fire is small, you have a clear exit behind you, and the room is not yet filling with smoke. When in doubt, get out and call the fire service. See our Extinguisher finder tool for class-specific guidance.
