1) Is Emergency Lighting a legal requirement.
Answer: The Industry Committee for Emergency Lighting states: The legal requirement is that non-domestic buildings must be safe at all times, in the event of a mains failure.
2) How long does Emergency Lighting have to be lit for?
Answer: The legal requirement for all Emergency Lighting is that the light source must remain on for 3 hours in the event of a mains failure.
3) What is BS5266
Answer: BS 5266-1 is the first in a series of Codes of practice on emergency lighting. It gives detailed guidance for Emergency Escape Lighting in the event of a mains failure within a building.
4) What is the minimum lux level for Emergency Lighting?
Answer: Lighting level requirements state that designers must be able to achieve a minimum of 1 lux anywhere on the centre line of the escape route. This illuminance must be provided for the full 3-hour duration and maintained throughout the emergency luminaires life.
5) Is LED lighting better for emergency luminaires.
Answer: There are many advantages in using LED technology for emergency luminaires over incandescent and fluorescent lamps. Mainly for their low running costs and energy performance. LED’s are today’s chosen choice for the majority of Emergency Lighting manufacturers.
6) How often should I test my Emergency Lighting?
Answer: The person responsible should be carrying out monthly and annual testing of the system and documenting the results. These tests consist of failing the mains supply to each emergency luminaire for at least 30 seconds (Flash test or function test) and then for the full duration of 3 hours annually.
7) How can I tell if my Emergency Luminaire has a fault?
Answer: A green led charge indicator tells the person responsible for testing that the Emergency Lighting system is operating correctly. A red flashing LED indicates a faulty battery or a lamp fault.
Self-test systems for Emergency Lighting will monitor the emergency circuit, with a weekly function test and an annual full duration test.
8) What is the difference between Non Maintained and Maintained lighting?
Answer: Non maintained Emergency Lighting is a luminaire which will only be lit from its battery back up in the event of a mains failure. A maintained luminaire can operate in normal operation and can be switched along with all other normal luminaires. In the event of a loss of mains power the luminaire will be lit from its battery back up but will have a lower emergency output.
9) Who is responsible for carrying out emergency testing of the luminaires?
Answer: A responsible person of a non-domestic building must ensure that the periodic checks are carried out and documented in a fire safety log and must be made available at any time.
10) What if I fail to maintain my emergency lighting?
Answer : Non compliant Emergency Lighting systems are breaking the law and can impose serious penalties for those responsible for the maintenance of the building. As all safety systems are regulated by the standards failure to carry out regular fire risk assessments can land you in serious trouble.
