In the UK, fire safety on construction sites is governed by The Regulatory Reform (Fire Safety) Order 2005. This legislation assigns the site manager, or the “responsible person,” the duty of assessing fire risks and implementing necessary safety measures. It’s essential to correctly position and utilise fire extinguishers, as well as to have effective alarm systems on site, to comply with these legal requirements.
Fire extinguisher placement on construction sites
Construction sites can often be chaotic and come with their own set of dangers. Having fire extinguishers positioned in the right spots allows workers to reach them easily if a fire breaks out, helping to manage or put out small fires before they escalate.
UK regulations and best practices suggest that all construction sites follow these guidelines regarding extinguisher placements, to prevent legal complications and ensure a safe working environment:
Near High-Risk Areas: Extinguishers should be located close to identified fire hazards, such as areas where hot works (e.g., welding, cutting) are performed, storage of flammable materials, or near fuel and machinery.
At Key Exits: Position extinguishers along escape routes and near exits so they are visible and easily accessible during an evacuation.
At Regular Intervals: On large sites, extinguishers should be placed at intervals not exceeding 30 metres to ensure no one has to travel far to access one.
Clearly Marked Locations: Extinguishers must be placed on stands or securely fixed to walls with clear signage to make them easily identifiable.

The importance of the correct fire extinguisher
Proper placement of fire extinguishers is crucial, but it’s just as vital to have the right type on hand to tackle any potential fires. Using the wrong extinguisher can worsen a fire or put the user at risk. Here are some common types of extinguishers and their specific uses:
Water Extinguishers: For Class A fires (wood, paper, cloth).
Foam Extinguishers: For Class A and B fires (flammable liquids like petrol).
CO2 Extinguishers: For electrical fires.
Powder Extinguishers: For multi-purpose use, including flammable gases.
It’s crucial to have the right type of fire extinguisher for the specific hazards present. Additionally, providing training for staff on the proper use of these extinguishers will significantly improve safety on site. Learn more about fire extinguishers in our handy guide.
Fire Alarm systems to inform all workers on site
A fire alarm system, whether manual or automatic, is essential for notifying workers in case of a fire on the premises. It’s important to install sounders, horns, or wireless alarm call points to ensure that everyone on site is alerted promptly. Having effective alarms, along with fire extinguishers and a robust evacuation plan are essential for protecting lives and property.
Prioritising these fire safety measures will ensure legal compliance and will reduce the risks on construction sites.
