Argonite
®
Engineered Fire Suppression System
38-KFSARG-000
7-10.5 Calculation of Room Volume
The volume to be used in calculating the required amount of Argonite shall be the
gross enclosure volume less the volume of any internal building structures, such as
columns. The volume shall include ventilation ducts and other related volumes.
7-10.6 Quantity of Agent Calculation
The fire extinguishing or inerting concentrations shall be used in determining the
Argonite design concentration for a particular flammable. For combinations of
flammables, the extinguishing or inerting value for the flammable requiring the greatest
concentration shall be used.
The ambient temperature of the enclosure is necessary to determine the proper
amount of Argonite to be delivered to the hazard.
If a common bank of cylinders is used for several hazards/systems, these shall be
calculated individually as if they were single systems. The number of cylinders required
for the cylinder bank will be based on the hazard with the largest demand, or the
largest demand required for protecting hazards that may be on fire simultaneously.
The quantity of extinguishant to be stored must, as a minimum, be adequate to
protect the largest hazard, and possibly other hazards if the risk exists of several
fires occurring simultaneously.
It is the project engineers responsibility that the design concentration is chosen
based on the following:
It is the project engineers responsibility that the design concentration is chosen
based on the following:
Integrity of the room, unclosable openings, unstoppable extraction ventilating,
etc.
Combustible flammables involved.
Quantity of flammables permitted in the enclosure.
Design concentration equal to or higher than required by the most demanding
flammable.
Ventilation conditions.
Elevation/altitude.
Escape possibilities.
Personal safety in general.
