Emergency lighting is designed to provide sufficient lighting to aid in illuminating escape routes during either the loss of mains power or any normal illimitations fail. Typically, these emergency lights would activate during emergency situations, such as result of a fire or power loss. This, otherwise, sudden darkness could be potentially dangerous to the occupants and cause damage to property or persons during the panic.
Emergency lighting should fully activate automatically during these situations without the need of switches. This would enable the occupants to safety evacuate the premises. It should be a consideration during design stage, to install emergency lighting system which would also comply with building regulations.
As emergency lighting is so vital in these situations, its extremely important that we have the confidence that the installation will operate correctly and efficiently.
Manual emergency lighting tests should be carried out frequently to ensure that compliance of the system.
The legal requirement, currently, states that emergency lighting must be tested in two ways:
• Monthly emergency lighting tests
All emergency lighting systems must be tested monthly. The test is a short functional test in accordance with BS EN 50172:2004 / BS 5266-8:2004.
The period of simulated failure should be sufficient for the purpose of this test while minimising damage to the system components, e.g. lamps. During this period, all luminaires and signs shall be checked to ensure that they are present, clean and functioning correctly.
• Annual emergency lighting tests
A test for the full rated duration of the emergency lights (e.g. 3 hours) must be carried out annually. The emergency lights must still be working at the end of this test.
The result must be recorded and, if failures are detected, these must be remedied as soon as possible.
At Entire Services, we can carry out a full emergency light compliance test and record details of our findings into a emergency light log book.
