In the UK, Building Regulation 2000 regulation
B1 covers the provision of safe and effective
means of escape from a building. Approved
Document B (2000) (ADB) is a published guide
to the Building Regulations, which specifies that
standards for the installation of escape lighting
should be according to BS 5266 Part 1.
BS 5266 Part 1:2005 is the umbrella standard which
refers to BS 5266 part 7:1999 (EN 1838), defining
emergency lighting levels of minimum 1.0 lux on the
centre line of an escape route, and 0.5 lux minimum
for open areas larger than 60m
2
.
British Standards are recognised worldwide, or are
commonly used as the basis of local standards.
NFPA 101 Life Safety Code standards require an
average of 10.8 lux with not less that 1.1 lux at any
point for escape routes.
We recommend that a copy of relevant local standards
are obtained prior to any design work.
We are pleased to supply data for any of our
luminaires in LUMDAT format, for use with Relux or
similar lighting packages.
We offer the following data for guidance to assist with design work to BS 5266 requirements.
Data is shown for a selection of 8W luminaires, for a typical 2.5 metre ceiling height.
For more information on luminaires please refer to the Emergi-Lite Emergency Lighting Catalogue
