Smoke control
In some premises, there may be some form
of smoke control provided for the safety of the
occupants and to assist firefighting (e.g. Smoke
and Heat Exhaust Ventilation Systems (SHEVS).
These systems are designed to restrict the spread
of fire and smoke usually by venting the heat
and smoke through the roof or via other routes
to the outside. Low level inlet air is essential
for the operation of SHEVS and all openings
for this purpose should not be obstructed.
Special down-stands may have been installed
to create a reservoir which will contain the
smoke and hot gases at roof level, while vents
allow the smoke to escape.
It is important that any smoke can flow easily
into the reservoirs and that nothing which
could cause an obstruction, such as large
displays, is fixed near the vents.
If your building has smoke vents fitted, or any
other form of smoke control, then you may
need to seek advice from someone who is
competent in such systems. Further information
on smoke control can be found from CIBSE
Guide E or from the BRE.
