fire-rated doors, windows, dampers or penetration seals. (Refer to the applicable
building code.)
5.2.3
To protect the integrity of the physical barriers associated with process confinement
systems, fire protection features should include the following:
o
A fire-extinguishing system to rapidly remove heat produced by fire to prevent
or minimize the pressurization of a process confinement and to rapidly extinguish
a fire to minimize the loading of ventilation system filters with combustion
products.
o
The introduction of the extinguishing agent in a way that does not result in
over-pressurization of the confinement barriers.
5.3
Fire Suppression Systems
5.3.1
All facilities of significance, including facilities where a fire could cause unacceptable
off-site consequences to health and safety, should be protected by an automatic fire
suppression system (usually a Wet Pipe Sprinkler System). A decision to install
another type of fire suppression system should be based on engineering analysis
performed by a fire protection engineer. DOE has, historically, considered an facility
with an MPFL in excess of $1 million as being significant from a property protection
standpoint.
5.3.2
In some circumstances, the need for automatic fire suppression systems should be
considered, despite the absence of explicit requirements, such as when the MPFL is
below $1 million or other limits imposed by DOE. Some examples of situations where
automatic fire suppression systems may be warranted are :
o
facilities that contain critical or long procurement time construction items;
o
a temporary-use trailer used as a control center for a vital one-time activity;
o
a facility with high public visibility or sensitivity (as defined by the AHJ);
o
electric power transformers with combustible contents that, of damaged, could
result in an extended shut-down of the facilities they serve;
o
facilities in which a fire could result in the accidental release of significant
quantities of toxic or hazardous materials or emissions (based on engineering
analysis);
o
facilities that can be protected by extending automatic fire suppression systems
from an adjacent protected facility or area at a low incremental cost;
o
facilities in which a fire could damage more important adjacent facilities;
o
facilities used to store hard to replace or irreplaceable records;
o
facilities that may warrant automatic fire suppression systems in the future; and
