Fire safety is a set of appropriate measures that are in place to minimize injury or loss of life during a fire. Fire safety and firefighting measures include those designed to prevent uncontrolled fires and those used to limit the spread and effects of fire after onset.
To prevent fires in the workplace, your hazard assessment should identify what could be causing the fire to start, namely the sources of combustion (heat or spark) and the materials that burn, and the people who may be at risk.
Once you have identified the risks, you can take appropriate steps to control them. Consider whether you can avoid them altogether or, if that is not possible, how you can reduce the risks and manage them. Also consider how you protect people from fire.
