Follow NFPA 204 for the
correct design of facilities
for emergency venting of
combustion products from
fires in non-sprinklered,
single-story buildings.
Manual and
computer-modeled solution methods aid in design
calculations. The equations or models provide the
designer with the necessary tools to develop vent designs
based on selected performance objectives related to a
specific building and a specific set of circumstances.
Engineering equations are included for calculating vent
flows, layer depths, and upper-layer temperatures based
on a prescribed burning rate.
Concepts were developed for venting fires in large,
undivided floor areas with ceiling heights sufficient to allow
the design fire plume and smoke layer to develop
(normally 4.6 m or greater). A limited amount of
information regarding venting in sprinklered buildings is
included. These provisions do not attempt to specify under
what conditions venting is to be provided; such conditions
depend on an analysis of the individual situation and on
local building code and fire code requirements.
