Choosing an Emergency Lighting System
Choosing the right emergency lighting system is one of the most important decisions for any commercial property owner, landlord or facilities manager. While emergency lighting may only be used during power failures or emergency situations, it plays a vital role in protecting lives and helping occupants evacuate safely.
Whether you are fitting out a brand-new building, renovating an existing premises or upgrading an ageing installation, selecting the correct emergency lighting system requires careful planning. Every building is different, and the most suitable solution depends on factors including building size, occupancy, layout and intended use.
At William Hale Fire & Security, emergency lighting systems are designed, installed, tested and maintained to meet current British Standards while providing reliable protection for businesses across a wide range of sectors.
What Is an Emergency Lighting System?
Emergency lighting automatically activates when the mains power supply fails.
Its purpose is to illuminate escape routes and safety equipment so occupants can leave the building safely during emergencies such as:
- Fire
- Electrical failure
- Power outages
- Building evacuations
- Severe weather incidents
Unlike standard lighting, emergency lighting operates from an independent battery supply, allowing it to continue functioning even when normal electricity is unavailable.
Why Choosing the Right System Matters
Emergency lighting is much more than a legal requirement.
The correct system helps:
- Protect occupants
- Reduce panic during evacuations
- Clearly identify escape routes
- Reduce trip hazards
- Assist emergency services
- Support legal compliance
Choosing an unsuitable system may result in inadequate illumination, expensive upgrades and unnecessary maintenance costs later.
Factors to Consider Before Choosing a System
Every building presents different challenges.
Before selecting emergency lighting, several factors should be assessed.
| Consideration | Why It Matters |
