Emergency Lighting & Exit Signage: Why They Matter & Compliance Tips
Fire Safety Guide #19 | A guide to the role of emergency lighting and exit signage in safe evacuation — plus key compliance requirements in the UK.
In a fire or power failure, visibility can vanish within seconds. Thick smoke, sudden darkness, and panic can make it extremely difficult for people to find their way out of a building safely. That’s where emergency lighting and exit signage become critical.
These systems provide clear guidance and reassurance during emergencies, helping people evacuate quickly — and they are also a legal requirement under UK fire safety regulations.

Why Emergency Lighting Matters
During a fire, the main lighting system often fails due to power loss or deliberate isolation. Without backup, escape routes become unsafe and evacuation slows down dramatically.
Emergency lighting provides essential support by illuminating corridors, stairwells, and exits so occupants can escape safely. It also helps reduce panic, as clear lighting and signage give reassurance and direction, while at the same time assisting firefighters in navigating
the building.
Beyond safety, compliance with UK law requires most non-domestic buildings to have a reliable emergency lighting system in place.

| Types of Emergency Lighting There are several categories of emergency lighting, each designed for different situations. Escape route lighting illuminates exit routes, doors, staircases, and corridors so people can clearly see and follow escape paths. Open area (anti-panic) lighting is used in larger spaces such as halls, warehouses, and open-plan offices. It prevents panic by ensuring there is sufficient light for safe movement towards escape routes. High-risk task area lighting is installed where dangerous processes are carried out, such as in factories or laboratories. It provides enough illumination to safely shut down equipment during an emergency. |
UK Compliance Requirements
Emergency lighting and exit signage are subject to strict compliance standards. The Regulatory Reform (Fire Safety) Order 2005 requires responsible persons to ensure safe evacuation procedures. The British Standard BS 5266-1 sets out the code of practice for emergency lighting, while BS EN 1838 specifies minimum light levels for escape routes and open areas.
To remain compliant, systems must provide at least three hours of illumination during a power failure, ensure all exit routes are lit (not just final exits), and undergo regular testing. A monthly function test checks that units activate, while an annual full-duration test ensures they can run for the full three hours. All tests should be recorded in the fire safety logbook.
Common Issues to Avoid
Despite clear requirements, common issues often undermine effectiveness. Blocked or poorly maintained exit signs can go unnoticed until an emergency. Dead batteries or faults in emergency lighting can cause lights to fail when needed most. Inadequate coverage in large or complex buildings is another frequent problem, as is incorrect placement of signage that leads to confusion instead of clarity.

Exit Signage: Showing the Way Out
Exit signs are just as vital as lighting. They must be clear, visible, and illuminated at all times — even during a power cut.
UK standards require signs to use the recognised running man pictogram, positioned above exit doors and along escape routes, with directional arrows where necessary. Signs must also be bright enough to be visible through smoke and darkness, ensuring no confusion in an emergency.

Conclusion
Emergency lighting and exit signage are vital, life-saving systems that make the difference between safe evacuation and chaos during a fire. They provide the clear, illuminated guidance people need to escape quickly and safely.
By ensuring correct installation, routine testing, and full compliance with UK standards, building owners and managers can be confident these systems will perform when it matters most.
