scope:

This standard specifies the requirements for materials installed in underground locations with regard to:

a) Flammability (including the risk of explosion);

b) Smoke emission;

c) Toxic fume emission.

This standard shall apply to installations:

a) In stations covered by Section 12 of the Fire Precautions (Sub-Surface Railway Stations) Regulations 1989 and 1-086;

b) In passenger and engineering trains;

c) In running tunnels;

d) In other locations that are not effectively separated from locations covered by a) or c) above;

e) In all other locations where risks from flammability, smoke or toxic fumes are not controlled to a level as low as reasonably practicable by other means..

Guidance is available in G-085.

Locations will be considered to be 'effectively separated' if they are either:

a) completely divided from the relevant stations and/or running tunnels by construction complying with Table 5, and there is no personnel access via that construction or;

b) configured such that it can be demonstrated that the stations/tunnels are adequately protected by means of fire and smoke control, in accordance with the relevant British Standards. This will require the support of a Fire Strategy, prepared, assured and accepted to be in accordance with 1-080.

This issue of the standard supersedes 1-085 A2
