EMERGENCY LIGHTING

Commercial Emergency Lighting

General Overview: Importance Of Emergency Lighting To Life Safety

Emergency lighting plays a critical role in life safety during emergencies such as fires, power outages, or natural disasters. Its primary function is to illuminate escape routes and safety-critical areas to ensure people can evacuate buildings safely and efficiently. Emergency lighting is vital for occupant safety during emergencies, ensuring that people can navigate to safety quickly and safely. To be effective, systems must be designed in compliance with relevant standards, regularly maintained, and tailored to the specific risks and layout of a building. Designing a robust emergency lighting system requires a balance between regulatory compliance, technical performance, and practical installation considerations.

Why It’s Essential:

  • Safe Evacuation: Guides occupants to exits, preventing panic and disorientation in low-visibility conditions.
  • Accident Prevention: Reduces the risk of trips, falls, or injuries during blackouts or smoke-filled environments.
  • Emergency Response Support: Assists firefighters, medics, and other emergency responders in navigating the building.
  • Compliance with Safety Codes: Essential for meeting legal requirements and avoiding liability.

Standards & Codes Governing Emergency Lighting Systems
Several international and national standards ensure emergency lighting systems are reliable and effective:

Key Standards:

  1. International Building Code (IBC)
    1. Mandates emergency lighting in stairways, corridors, and exit paths.
    2. Requires systems to activate automatically upon power loss.

Frequently Asked Questions About Commercial Emergency Lighting

Emergency lighting provides illumination when the normal lighting supply fails, helping people find escape routes, identify exits and move safely through a building.

It plays an essential role in commercial fire safety by reducing the risk of accidents, confusion and delays during an evacuation.

A suitable emergency lighting system helps occupants navigate corridors, stairways, changes in floor level and other areas where poor visibility could create danger.

Businesses should ensure their emergency lighting reflects the building’s layout, occupancy and fire safety strategy.

Many commercial premises require emergency lighting to provide adequate illumination when normal lighting fails.

In England and Wales, the Regulatory Reform (Fire Safety) Order 2005 requires emergency routes and exits to have suitable emergency lighting where necessary. The Responsible Person must also maintain relevant fire safety equipment in effective working order.

The building’s fire risk assessment, layout, occupancy and escape arrangements help determine the emergency lighting requirements.

Businesses should seek competent advice rather than assume that every building needs the same type or quantity of emergency lighting.

Different emergency lighting systems perform different functions within a building.

The main types include:

  • Escape route lighting – Illuminates corridors, stairways, exits and other routes that occupants use during evacuation.
  • Open area lighting – Helps occupants orient themselves and move towards escape routes in larger open spaces.
  • High-risk task area lighting – Provides appropriate illumination where people must safely stop hazardous processes or equipment.
  • Maintained emergency lighting – Operates during normal conditions and continues providing light when the normal supply fails.
  • Non-maintained emergency lighting – Activates when the normal lighting supply fails.

Emergency lighting specialists can recommend the appropriate combination of lighting types based on your premises and fire safety requirements.

Emergency lighting should provide suitable illumination wherever occupants need it to evacuate safely or manage particular risks during a lighting failure.

Common locations include:

  • Emergency exits and designated escape routes
  • Corridors, stairways and changes in floor level
  • Changes of direction and intersections along escape routes
  • Open areas that require emergency illumination
  • Locations of relevant firefighting equipment and manual call points
  • Accessible toilets and other facilities where the design requires emergency lighting
  • High-risk work areas where occupants need to shut down equipment safely
  • External areas immediately outside final exits where appropriate

A competent designer should assess the building and determine suitable fitting positions, lighting levels and coverage.

Commercial emergency lighting requires regular inspection and testing to confirm that it operates correctly when the normal lighting supply fails.

BS 5266-1:2025 and BS EN 50172:2024 provide guidance on routine testing and maintenance.

The recommended testing arrangements include:

  • Monthly functional testing – Briefly simulate a failure of the normal supply and confirm that each relevant emergency luminaire and internally illuminated exit sign operates.
  • Annual full-duration testing – Test each luminaire for its full rated operating duration and check that it continues to provide the required illumination.
  • Regular visual checks – Look for damage, obstructions and warning indicators, following the requirements of the installed system.
  • Periodic light-level verification – Arrange appropriate photometric verification at intervals not exceeding five years, in line with the current standard.

Record the results and arrange prompt corrective action when a test identifies a fault.

Emergency lighting must operate for the duration that the building’s design and applicable standards require.

Many commercial emergency lighting systems provide a three-hour rated duration, particularly where occupants may not evacuate immediately or the building may need to remain in use after a supply failure.

Some applications permit a shorter rated duration when the building’s evacuation and reoccupation arrangements support it.

A competent emergency lighting designer should confirm the appropriate duration for your premises rather than assume that every installation needs the same battery capacity.

During a maintenance visit, a competent engineer checks the condition and operation of your emergency lighting system.

Depending on the installation and agreed service scope, the visit may include:

  • Inspecting emergency lighting fittings and illuminated exit signs
  • Checking batteries, charging indicators and relevant power supplies
  • Testing the operation of emergency lighting controls
  • Carrying out appropriate functional or full-duration tests
  • Identifying damaged, faulty or deteriorating components
  • Reviewing system records and maintenance history
  • Recording test results and recommending corrective action

Engineers should also consider whether changes to the building have affected the suitability of the existing emergency lighting arrangement.

Yes. SS Systems provides commercial emergency lighting services and can discuss improvements to existing installations.

Our team can assess your current equipment, identify areas requiring attention and recommend suitable upgrades or replacements based on your building’s needs.

Possible improvements include replacing ageing fittings, addressing inadequate coverage, improving exit signage or introducing suitable self-testing technology.

Any proposed changes should reflect the building’s fire risk assessment, emergency lighting design requirements and relevant British Standards.

Manually tested emergency lighting requires a person to initiate the appropriate test, check the results and record any faults.

Self-testing emergency lighting uses built-in technology to carry out scheduled checks automatically. Depending on the system, it may provide local fault indicators or send results to a central monitoring platform.

Self-testing systems can help businesses:

  • Reduce the time staff spend carrying out routine functional tests
  • Identify certain faults more quickly
  • Improve the consistency of scheduled testing
  • Support maintenance reporting and record keeping

However, automatic testing does not remove the need for appropriate inspections, fault resolution and competent maintenance.

Contact SS Systems to discuss your commercial emergency lighting requirements, whether you need a new installation, improvements to an existing system or ongoing inspection and maintenance.

Our team can review your premises and help identify suitable next steps based on the building’s layout, use and fire safety arrangements.

We can also discuss planned maintenance and testing services to help you keep your emergency lighting reliable throughout the year.

Advice When Choosing, Installing and Maintaining Commercial Emergency Lighting

Before selecting emergency lighting, review your building’s fire risk assessment and evacuation arrangements.

Identify the areas where occupants need illumination if the normal lighting supply fails. Consider escape routes, stairways, changes in floor level, open areas and locations where people carry out hazardous tasks.

Pay particular attention to:

  • The number of occupants and their familiarity with the building
  • People who may need additional assistance during evacuation
  • The location and complexity of escape routes
  • Areas without sufficient natural lighting
  • Changes in floor level and direction
  • Equipment or processes that require a safe shutdown

Use these findings to develop an emergency lighting design that reflects the actual risks and operating conditions of your premises.

Different buildings require different emergency lighting arrangements. Select a system that suits your premises rather than choosing fittings based on appearance or purchase price alone.

Consider the following options:

  • Maintained lighting – Provides illumination during normal operation and continues operating when the normal supply fails.
  • Non-maintained lighting – Activates when the normal lighting supply fails.
  • Self-contained fittings – Use individual batteries within or associated with each emergency luminaire.
  • Central battery systems – Supply emergency lighting from a central power source.
  • Self-testing systems – Carry out programmed tests and indicate or report certain faults.

Assess the installation costs, maintenance requirements, building size and long-term operational needs before selecting a system.

A competent designer can help determine which arrangement offers the most suitable protection for your premises.

Ask your emergency lighting provider to design, install and maintain the system in accordance with the standards relevant to your premises.

Important standards include:

  • BS 5266-1:2025 – Provides guidance on emergency lighting for premises.
  • BS EN 1838:2024 – Sets out lighting requirements for emergency lighting applications.
  • BS EN 50172:2024 – Covers emergency escape lighting systems, including relevant inspection and testing arrangements.

Check that the proposed design addresses suitable illumination levels, fitting locations, operating duration, emergency exit signage and maintenance access.

Request appropriate design, installation and commissioning documentation so your organisation can understand and maintain the system correctly.

Remember that compliance depends on the complete installation and its suitability for the building, not simply the certification of individual light fittings.

Emergency lighting must help people identify and follow safe escape routes when normal lighting fails.

Review the position of emergency luminaires and exit signs throughout your premises, particularly around stairways, corridors, changes of direction and final exits.

Important considerations include:

  • Escape route visibility – Provide suitable illumination along designated routes.
  • Exit identification – Position signs so occupants can identify the correct direction of travel.
  • Changes in level – Address stairs, ramps and other areas where reduced visibility creates additional risks.
  • Fire safety equipment – Provide appropriate illumination at relevant manual call points and firefighting equipment.
  • External safety – Consider lighting immediately outside final exits where the design requires it.
  • Accessibility – Account for occupants who may need additional time or assistance during evacuation.

Do not allow new partitions, shelving, displays or other alterations to obstruct emergency lighting or exit signage.

Regular testing helps confirm that emergency lighting will operate when occupants need it.

Follow a documented testing schedule that reflects BS 5266-1:2025, BS EN 50172:2024 and the requirements of your installed system.

Your programme should include:

  • Monthly functional tests – Briefly simulate a normal lighting supply failure and confirm that the relevant emergency luminaires operate.
  • Annual full-duration tests – Confirm that each luminaire operates for its full rated duration.
  • Visual inspections – Check for damage, obstructions and other visible problems.
  • Photometric verification – Arrange measured checks of emergency lighting performance at intervals not exceeding five years, in accordance with the current standard.
  • Maintenance records – Record test results, faults and corrective actions.

Arrange full-duration testing at a suitable time because discharging the batteries temporarily reduces the system’s available emergency operating capacity.

Allow batteries to recharge and introduce appropriate precautions where necessary before returning affected areas to normal use.

Emergency lighting relies on suitable backup power to operate when the normal lighting supply fails.

Battery deterioration, charging faults and damaged components can reduce the system’s ability to provide the required illumination.

Watch for the following warning signs:

  • Emergency lights that fail to illuminate during testing
  • Fittings that switch off before completing their rated duration
  • Fault indicators or abnormal charging signals
  • Damaged or deteriorating light fittings
  • Obstructed or poorly positioned emergency luminaires
  • Missing or unclear exit signs

Report faults promptly and arrange suitable repairs through a competent specialist.

Where a fault affects an escape route or another safety-critical area, assess the risk immediately and introduce appropriate temporary safety measures until engineers restore the system.

Maintain clear records of your emergency lighting inspections, tests, maintenance visits and repairs.

Accurate documentation helps you identify recurring problems, plan future servicing and demonstrate how your organisation manages its fire safety responsibilities.

Your records should include:

  • The location and identification of emergency lighting fittings
  • System design and commissioning information
  • Monthly functional test results
  • Annual full-duration test results
  • Relevant light-level verification records
  • Fault reports and remedial recommendations
  • Repair dates and confirmation of completed work
  • Changes to the system or building layout

Assign responsibility for maintaining the records and ensure the relevant people can access them when required.

Review outstanding faults regularly rather than waiting until the next scheduled maintenance visit.

Changes to your premises can affect the suitability of your emergency lighting system, even when every fitting continues to operate correctly.

Review your emergency lighting arrangements whenever you alter the building layout, change occupancy levels or introduce new activities.

Examples include:

  • Installing new partitions or changing room layouts
  • Moving or adding warehouse racking
  • Changing designated escape routes
  • Extending or refurbishing the premises
  • Introducing new high-risk machinery or work processes
  • Changing the use of rooms or work areas
  • Installing signs or displays that affect visibility

Ask a competent specialist to assess whether the changes require additional luminaires, repositioned fittings, updated exit signage or further testing.

Update the relevant system documentation after completing any modifications.

Choose an emergency lighting provider with suitable experience in commercial system design, installation, testing and maintenance.

Ask how the provider will assess your premises, establish the required lighting coverage and support the system throughout its working life.

Before agreeing to a service, consider:

  • The provider’s experience with your type of premises
  • Relevant technical competence and certifications
  • Design and installation arrangements
  • Commissioning and testing procedures
  • Maintenance schedules and service documentation
  • Support for repairs, upgrades and replacement equipment

SS Systems provides commercial emergency lighting services and can help businesses review their installation, testing and maintenance requirements.

Bonus Tip: Keep an up-to-date emergency lighting layout drawing alongside your maintenance records. Mark the location and identification number of each fitting, exit sign and relevant test point. This helps staff complete routine checks, allows engineers to locate equipment efficiently and makes it easier to identify missing or overlooked fittings after building alterations.
