Fire can destroy a business and take lives in a single afternoon. The encouraging part is that it follows simple rules — understand them and prevention and safe escape become straightforward. This guide covers how fire works, where the risks hide and what the 'responsible person' must do under UK law.
Fire is simpler than it looks
Every fire needs three things together: heat, fuel and oxygen. Remove any one and it can't burn. That single idea underpins almost every fire precaution, from housekeeping to extinguisher choice.
Grasp the triangle and the rest of fire safety falls into place.
Where fire risk hides at work
Most workplace fires come from a few predictable sources. Tap each to see how to keep it in check.
The spark
Faulty wiring, hot works, heaters, cooking and smoking are the usual starters. Control them first.
The fire triangle
Heat, fuel, oxygen — remove any side and the fire goes out. It's the logic behind every control you'll use.
Heat
Ignition sources — flames, sparks, hot surfaces, electrical faults. Remove the heat, no fire.
Fuel
Anything combustible — paper, wood, fabrics, liquids, gases, even fine dust.
Oxygen
Always around us. Smothering or starving a fire of oxygen is how many extinguishers work.
On the alarm, get out and stay out. Property can be replaced — never go back for belongings.
What to do, in order
Fire safety is four things done well — prevent, detect, escape and, only if safe, fight:
Prevent it
Control ignition sources, store flammables safely, and keep waste and clutter down.
Detect it early
Working alarms and detectors, tested regularly, buy the minutes that save lives.
Get out
On the alarm, leave by the nearest safe exit, go to the assembly point — don't go back for belongings.
Fight it only if safe
Small, contained fire and a clear escape behind you? The right extinguisher may help. If in doubt, get out.
What the law requires
Under the Regulatory Reform (Fire Safety) Order 2005, the 'responsible person' must manage fire risk in the premises and keep people safe. In practice that means:
- Carry out a fire risk assessment
- Provide and maintain alarms, signs and extinguishers
- Keep escape routes clear and clearly marked
- Train staff and run evacuation drills
