Most fires are preventable. Those responsible for workplaces and other buildings to which the public have access can avoid the risk of fires by taking responsibility for – and adopting the right behaviours and procedures. This section covers general advice on fire safety and also provides guidance on substances that can cause fires, sparks and explosions.
General Fire Safety Hazards
Fires need three things to start – a source of ignition, a source of fuel and oxygen!
- Sources of ignition include heaters, lights, naked flames, electrical equipment and smokers’ materials such as cigarettes, matches and lighters as well as anything else that can get very hot or cause sparks.
- Sources of fuel include wood, paper, plastic, rubber or foam as well as loose packaging materials, waste rubbish and furniture.
- Sources of oxygen include the air around us as well as wind or a slight breeze that may blow through the venue.
What do I Have to Do?
Employers and/or building owners or occupiers must carry out a fire safety risk assessment and keep it up to date. This shares the same approach as health and safety risk assessments and can be carried out either as part of an overall risk assessment or as a separate exercise. Based on the findings of the assessment, employers need to ensure that adequate and appropriate fire safety measures are in place to minimise the risk of injury or loss of life in the event of a fire.
To help prevent fires in the workplace, your risk assessment should identify what could cause a fire to start. For example – sources of ignition and substances that burn as well as the people who may be at risk. Once you have identified the risks you can take appropriate action to control them. Consider whether you can avoid them altogether or if this is not possible – how you can reduce the risks and manage them. Also consider how you will protect people if there is a fire.
- Carry out a fire safety risk assessment.
- Keep sources of ignition and flammable substances apart.
- Avoid accidental fires. For example – make sure heaters cannot be knocked over.
- Ensure good housekeeping at all times. For example – avoid build-up of rubbish that could burn.
- Consider how to detect fires and how to warn people quickly if they start. For example – installing smoke alarms and fire alarms or bells.
- Have the correct fire-fighting equipment for putting a fire out quickly.
- Keep fire exits and escape routes clearly marked and unobstructed at all times.
- Ensure your workers receive appropriate training on procedures they need to follow, including fire drills.
- Review and update your risk assessment regularly.

- The Welsh Government also provides information.
- The Scottish Government provides similar information to help you meet your responsibilities under the Fire (Scotland) Act 2005.
- The HSE website has guidance on fire safety in the construction industry.
The Regulatory Reform (Fire Safety) Order 2005 covers general fire safety in England and Wales. In Scotland, requirements on general fire safety are covered in Part 3 of the Fire (Scotland) Act 2005, supported by the Fire Safety (Scotland) Regulations 2006. In the majority of premises, local fire and rescue authorities are responsible for enforcing this fire safety legislation. HSE has enforcement responsibility on construction sites, for nuclear premises, and on ships under construction or undergoing repair.
Dangerous substances that cause fire and explosion
Work which involves the storage, use or creation of chemicals, vapours and dusts etc. that can readily burn or explode is hazardous. Each year people are injured at work by flammable substances accidentally catching fire or exploding. This section does not cover explosives – our website has more detailed information on explosives and similar substances. It also has information on gas safety.
What are the hazards?
Many substances found in the workplace can cause fires or explosions. These range from the obvious! For example – flammable chemicals, petrol and cellulose paint thinners and welding gases, to the less obvious – engine oil, grease, packaging materials and dusts from wood, flour and sugar.
It is important to be aware of the risks and to control or get rid of them to prevent accidents.
What do I have to do to help prevent accidental fires or explosions? First, you need to identify the following:
- What substances, materials, processes etc. have the potential to cause such an event? For example – substances that burn or can explode and what might set them alight.
- The people who may be at risk/harmed.
Once you have identified the risks, you should consider what measures are needed to reduce or remove the risk of people being harmed. This will include measures to prevent these incidents happening in the first place, as well as precautions that will protect people from harm if there is a fire or explosion.
Key points to remember
- Think about the risks of fire and explosions from the substances you use or create in your business and consider how you might remove or reduce the risks.
- Use supplier safety data sheets as a source of information about which substances might be flammable.
- Consider reducing the amount of flammable/explosive substances you store on site.
- Keep sources of ignition. For example – naked flames, sparks and substances that burn. For example – vapour and dusts.
- Get rid of flammable/explosive substances safely.
- Review your risk assessment regularly.
- Maintain good housekeeping. For example – avoid build-up of rubbish, dust or grease that could start a fire or make one worse.
You also need to consider the presence of dangerous substances that can result in fires or explosions as part of your fire safety risk assessment. This is required under the Regulatory Reform (Fire Safety) Order 2005 (in England and Wales) and under Part 3 of the Fire (Scotland) Act. The Fire and Rescue Authorities deal with general fire safety matters in workplaces apart from on construction sites including shipbuilding where these are dealt with by HSE or its agents. Enforcement responsibility for fire safety where dangerous substances are kept and used generally lies with HSE (or local authorities if they inspect the premises).
