Emergency Lighting & Exit Signage

When a fire or power failure plunges a building into darkness, the difference between an orderly evacuation and a fatal panic is whether people can clearly see the escape route and exit signs. Emergency lighting and exit signage are not optional extras — they are mandated by the Kenya Building Code, OSHA 2007, and international fire life-safety standards for all commercial, industrial, institutional, and multi-storey residential buildings. Lance Security designs, supplies, installs, and maintains emergency lighting systems and illuminated exit signs across Kenya, ensuring your building meets every regulatory requirement and your occupants can always find their way out safely.

Emergency Lighting Types

Escape Route Lighting

Escape route luminaires illuminate the path along corridors, stairwells, and passageways that form the designated evacuation route. They must activate automatically within five seconds of mains power failure and provide at minimum 1 lux at floor level along the centre of the escape route (BS EN 1838 requirement). In practice, we design for 3–5 lux at floor level to give comfortable visibility for evacuating occupants. Escape route lights must remain on for the full duration required by the building category — typically one hour for offices and retail, three hours for hospitals, hotels, and public assembly buildings.

Open Area (Anti-Panic) Lighting

Anti-panic lighting prevents panic and enables safe movement in large open areas such as retail floor plates, assembly halls, hotel lobbies, and open-plan offices. It must provide a minimum of 0.5 lux across the occupied area to allow occupants to safely identify and move towards escape routes. Anti-panic lighting activates instantly on mains failure and remains on for the required duration.

High-Risk Task Area Lighting

Some work areas require higher illuminance during evacuation to allow a safe process shutdown or to protect a person in a position of danger before they leave. Examples include security control rooms, industrial process areas, emergency power switch locations, and patient care areas in hospitals. High-risk task area lighting provides a minimum of 10% of normal task illuminance or 15 lux (whichever is greater), enabling safe cessation of work before the area is evacuated.

Self-Contained vs Central Battery Systems

Self-Contained Emergency Luminaires

Each fitting contains its own battery charger and battery pack. When mains power fails, the fitting switches automatically to battery power. Self-contained units are the most common approach for small to medium commercial buildings — they are straightforward to install, require no central plant, and a failure of one unit does not affect others. Batteries typically have a service life of four years, and fittings are replaced or relamped at that interval.

Central Battery Systems

A single central battery bank — typically located in a battery room or riser cupboard — powers all emergency luminaires throughout the building via dedicated wiring. Central systems are preferred for large buildings (hospitals, airports, shopping malls, high-rise offices) where maintaining hundreds of individual self-contained batteries would be impractical. They also allow system-wide testing and monitoring from a single point. All wiring from the central battery to the luminaires must use fire resistant cables to maintain the supply during a fire.

Exit Signs & Directional Signage

Illuminated exit signs must be installed above or adjacent to every final exit door and at every change of direction along the escape route, so that occupants can always see the next sign from their current position. We supply LED exit signs in green-on-white format (ISO 7010 compliance, the international standard adopted by Kenya) with built-in battery backup. Photoluminescent (glow-in-the-dark) signs are used as a supplement in areas where maintained lighting is not required, such as fire equipment stores and external paths.

Kenya Building Code Requirements

• Emergency lighting required in all buildings with floor area above 500 m², all buildings above two storeys, all places of assembly, all hotels, hospitals, schools, and underground spaces.
• Exit signs required above every final exit and at every point along the escape route where the direction is not self-evident.
• Duration: minimum 1 hour for most commercial buildings; 3 hours for sleeping risk (hotels, hospitals) and high-occupancy assembly buildings.
• Testing: Monthly function test (activate battery, verify luminaires illuminate for minimum 25% of rated duration); Annual full-duration test (let batteries run for the full rated duration and confirm all units remain illuminated).
• Maintenance records kept in the fire safety log book.

Design, Installation & Testing

Our design produces a lighting layout drawing showing luminaire positions, spacings, illuminance calculations, and the wiring schematic for the chosen system type. All testing at handover follows BS EN 62034 (for self-contained) and BS EN 50171 (for central battery systems). We provide commissioning certificates and a full test record to start your ongoing maintenance log.

Our maintenance contracts include the monthly function tests, annual full-duration tests, battery and lamp replacement, and compliance documentation. Request an emergency lighting assessment and ensure your building's escape routes are always visible when they matter most.
