Emergency Lighting ●From previous page

● Providing guidance on the implementation of requirements and solutions, particularly on suitability and energy usage. ● Providing guidance on election and planning the scheme of required equipment. ● Including reference to development of new system types. ● Including guidance on illumination of external 'open balcony' approaches to flats/maisonettes within blocks. ● Including guidance on illumination of swimming areas within swimming pools. ● Adding guidance on the installation process, testing and commissioning. The update was required to reflect the

development and changes of national and international standards, but also to reflect the practice of allowing people to stay in premised in case of power supply failures rather than evacuation them unnecessarily. Among the most significant changes within the revised standard are the following:

‘Stay put’ policy Whilst emergency lighting recommendations are, primarily, intended to contribute to the safe evacuation of buildings on loss of the normal lighting, for some premises an immediate evacuation of all occupants may not be the most appropriate option in the event of a power supply interruption. In premises occupied by unwell, infirm or vulnerable people – such as care or nursing homes – evacuation, in case of mains failure, may be difficult and involve safety risks. Therefore the risk assessment may determine that it is more appropriate for the occupants to remain in the building for extended periods on loss of the normal lighting supply. As a result the revised edition of BS5266-1 includes recommendations and guidance for a ‘stay put’ strategy. For some premises, particularly those in locations vulnerable to frequent power supply interruptions, a ‘stay put’ strategy may be the most appropriate option. However, where

premises implement such a system, the safety of persons remaining in the premises must not be compromised.

Emergency safety lighting To provide a safe environment for those who remain in the building, higher levels of illuminance and additional signage may need to be provided in particular areas or rooms. Lighting provided for such purposes is defined as Emergency Safety Lighting in BS5288-11 and should satisfy the following recommendations: ● It should provide a minimum illuminance of 1 lux over the floor area that people might need to cross, although based on risk assessment, higher levels may be needed. ● Escape route and other safety signs should comply with the relevant clauses in the standard. For example, an escape route sign designated as E001 in BS EN ISO 7010:2012+A5 should be used with the appropriate directional arrow in accordance with Table 1 of BS 5499-4:2013.

Fire risk assessment In the past the relevant fire officer used to issue a fire certificate, but this has now been changed and it is now a legal requirement for the end user to do a full site specific risk assessment. They have a duty of care to ensure full compliance and this is a 5-fold process: ● Identify fire hazards ● Identify people at risk ● Evaluate the risk ● Record all findings ● Keep assessment under annual review Although BS5266 covers emergency

lighting, it should be noted that other documents should be considered such as Approved Document B and Approved Document M, as well as the Equality Act [DDA] and BS9999 (Fire Safety in Buildings). These should be read in conjunction as these documents also cover emergency lighting and fire safety. You should also check the government guidance documents available on then search fire safety.

Verifying existing premises Where valid emergency lighting system documentation cannot be provided for an existing installation, such as the original completion certificates, the installation should be inspected for compliance with current emergency lighting standards and a certificate of verification should be completed and supplied to the owner/occupier of the premises. This is designed to provide feedback to the owner/occupier of the premises, on the existing system; identifying any deviations present and recommending the actions necessary to address them. The completed verification certificate and

associated documentation such as the log book and the records of remedial works will then provide a substitute system of documentation that may be used, when necessary, to provide evidence of compliance with current lighting standards. 36 | electrical wholesalerSeptember 2018
