Fire kills and injures many people every year in the UK. On construction, demolition or refurbishment sites there can be a high risk of fire. Smoke and fire can spread rapidly and this risk can increase depending on the stage of the project.
How fire starts
For fire to start there must be three elements (the fire triangle).
- Heat or ignition (such as a spark).
- Fuel (something that burns).
- Oxygen (air).
Fire feeds on fuel and oxygen. A fire can be put out by removing any one of the following.
- The heat or ignition source (cooling with water).
- The fuel (starving, for example, by turning off the gas supply).
- The oxygen (smothering with foam or a fire blanket).
