What are the different types of emergency lights and why?
There are three main types of emergency lighting. Maintained, Non-Maintained, or Combined and are used depending on the type of the building and it’s associated risks.
Maintained Emergency Lighting System
A Maintained emergency light is a luminaire in which the emergency lamps are on at all times. Maintained fire exit signs are also used in public spaces even where these are well lit to offer clear escape route guidance in evacuation situations where the power does not fail.
Non – Maintained Emergency Lighting System
A Non-maintained emergency lighting system is a luminaire whose emergency lamps only come on when the power supply to the normal lighting fails. A Non-maintained emergency lighting system is the typical choice for a workplace or similar environment in which artificial lighting is normally deployed while the premises are occupied.
Combined Emergency Lighting System
Combined emergency lighting: a luminaire containing two or more lamps, at least one of which is energised from the emergency lighting supply and the other(s) from the normal lighting supply. A combined emergency light can be either maintained or non-maintained.
Where should I have the lighting installed in my premises?
Emergency Lighting units and signs should illuminate all escape routes within a premises, especially where the exit route or final exit is not readily identifiable, a maintained emergency exit light should be utilised rather than a non maintained unit. Access to fire alarm call points and fire fighting equipment should also be clearly illuminated.
Escape route lighting – ensures that the means of escape is illuminated so occupants can safely leave the building via the designated escape route or routes.
Open area lighting – provided to minimise panic and ensure there is sufficient illumination to allow the occupants of a building to reach a place where an escape route can be identified.
High risk task area lighting – provides illumination for the safety of people involved in a potentially dangerous process or situation and to enable proper shut-down procedures for the safety of the operator and other occupants of the premises.
How do you ensure your emergency lighting is going to be sufficient?
Consultation & Design
The designer of the system, and the risk assessor (if different), should consult regarding the:
- type of system.
- area/s to be covered.
- buildings intended use.
- duration of emergency coverage required.
- maintenance requirements of the system
All of which must be confirmed during the design phase. The design should be completed by a competent fire safety company to ensure it is done to BS standards. If you are based in Gloucestershire or the southwest please do not hesitate to call us on 01452 645073.
Commissioning & Certification
How do you ensure your emergency lighting is compliant?
BS 5266 and the European Standard both require written declarations of compliance to be available on site for inspection once an emergency lighting system has been installed. This ensures that you can demonstrate your system has been installed to all the correct standards
On completion of the installation, MD Bros will always provide a certificate of installation for this purpose. We are also an NICEIC accredited company, so where needed, we will also notify building control of any amendments.
