7-21.4 Pressure Relief Vents (If Used)
Relief vent openings shall be provided with a warning sign to caution personnel of
possible pressure discharge and hazardous atmosphere.
7-22 ALARM AND DETECTION
This manual does not cover detection and control systems. However, it shall be noted that
in systems requiring more than 100 cylinders released simultaneously, additional solenoid
valve(s)one per every 100 cylindersshall be energized simultaneously; and that in the
case of selector valve systems, a solenoid valve for the selector valve shall also be energized.
When selecting a detection and control system, evaluate the ambient environmental
conditions to determine the appropriate device and sensitivity in order to prevent false
discharges while still providing the necessary earliest actuation. In high airflow environments,
air-sampling detection devices should be considered.
Detectors installed at the maximum spacing as listed or approved for fire
alarm use can result in excessive delay in agent release, especially where
more than one detection device is required to be in alarm before automatic
actuation results (cross zone system). Where there is a risk of a flammable
atmosphere forming, the spacing and location of flammable vapor detectors
requires careful consideration to avoid excessive delay in agent release.
Hazards associated with fast growing fires would include, but are not limited to, flammable
liquid storage or transfer and aerosol filling areas.
