SAFETY PRECAUTIONS, OCCUPIED SPACES
In areas that potentially could be occupied, the following must be provided.
Time delay devices:
-
For applications where a discharge delay does not significantly increase the
threat from fire to life or property, extinguishing systems shall incorporate a
predischarge alarm with a time delay sufficient to allow personnel evacuation
prior to discharge.
-
Time delay devices shall only be used for personnel evacuation or to prepare the
hazard area for discharge.
Automatic/Manual switch and lockout devices where required.
Note:
Although lockout devices are not always required, they are essential in some
situations, particularly for some specific maintenance functions.
Exit routes that shall be kept clear at all times, emergency lighting and adequate
directional signs to minimize travel distances. Outward-swinging, self-closing doors
that can be opened from the inside, including when locked from the outside.
Continuous visual and audible alarms at entrances and designated exits inside the
protected area as well as continuous visual alarms outside the protected area that
operate until the protected area has been made safe. Where required, predischarge
alarms that are distinctive from other alarm signals and that will operate immediately
upon initiation of the time delay cycle upon detection of a fire.
Appropriate warning and instruction signs.
Means for prompt natural or forced-draft ventilation of protected spaces after any
discharge of extinguishant. Forced-draft ventilation will often be necessary. Care
shall be taken to completely dissipate the hazardous atmosphere and not just move
it to other locations, as Argonite and decomposition products are heavier than air.
Provide instruction and conduct drills for all personnel within or near protected areas,
including maintenance or construction personnel who may be brought into
the area, to ensure their correct response upon system operation.
In addition to the above, the following are recommended:
-
Self-contained breathing apparatus should be available and personnel trained in its
use.
-
Personnel should not enter the enclosure until it has been verified as being safe.
