1.3. Pressure Relief Device (PRD)
1.3.1. PRD Inspection
Pressure relief devices (PRD) are installed
in the vent lines running from each tank.
Earlier tank versions also included a PRD
installed directly in the tank end. All PRD’s
must be connected in a manner that
ensures that the PRD can vent the contents
of the tank regardless of whether the
tank valve is in the closed or open position.
Only quick response PRD’s approved for
use with Lincoln Composites tanks are to
be used with these tanks. Approved
devices are listed in Section 7 of the Parts
Manual for this vehicle. The parts are available
from NFIL Parts Division.
Pressure relief devices are sensitive to
temperature. DO NOT steam clean the
pressure relief devices. DO NOT expose
them to temperatures which exceed
180°F (82°C)
Inspection of the PRD should include the
following:
1. Examine the PRD assemblies for damage.
The PRD assemblies should not be
deformed or show other signs of damage.
Damaged PRD assemblies must be
replaced.
Before depressurizing the container,
ground the venting orifice with a 3-
gauge wire minimum to an appropriate
ground source at least 8′ (2.44 meters)
in the ground. Rapid discharge can
generate a static electrical charge,
which may be sufficient to ignite the
escaping gas. When venting the
container, it must be in a well-ventilated
area free of ignition and heat sources.
DO NOT vent the container in an area
where the flammable gas may
accumulate and ignite.
2. Leak testing of the interfaces between the
PRD and tank or vent lines. These interfaces
should be serviced if any leakage is
observed.
1.3.2. PRD Removal
The following PRD removal and installation
instructions are written to accommodate
the various configurations used, including:
❒ PRD’s installed inline and located near the
solenoid end of the tank. See “Fig. 1: Inline
PRD Installation” on page 5. These PRD’s
will be connected with either tee or elbow
fittings.
❒ PRD’s installed inline and located nearest
the opposite end of the tank. These PRD’s
will be connected to the vent lines with
either straight fittings or, on earlier versions,
with tee and elbow fittings. See “Fig.
1: Inline PRD Installation” on page 5.
❒ PRD’s installed directly in the threaded
boss of the tank end opposite the solenoid
valve. These PRD’s are connected to the
vent line with an elbow. See “Fig. 2: Tank-
End PRD Installation” on page 7.
Use the appropriate removal and installation
procedure to suit the PRD configuration
being serviced.

1.3.2.6. Installation (PRD installed directly in
end of tank)
DO NOT overtighten PRD. Threaded
boss in tank is made of aluminum and
can be damaged if PRD is
overtightened. ALWAYS torque to
specification.
DO NOT apply excessive lubricant to
the O-ring on the PRD. Excessive
lubricant can prevent the O-ring from
sealing properly. Use only a minimal
amount of lubricant on the O-ring.
1. Lightly lubricate the new O-ring with silicone
grease and ensure it is properly
installed in the O-ring groove of the PRD.

a. Fully retract the adjustment nut on the
elbow fitting.
b. Lightly lubricate new O-ring with silicone
grease and install against the
backup washer on the elbow fitting.
c. Thread the elbow fitting into PRD until
lightly seated.
d. Loosen elbow fitting sufficiently to align
with vent line when installed.
e. Tighten adjustment nut until lightly
seated. Do not final tighten adjustment
nut at this time.
4. Align elbow with vent line and insert vent
line into fitting until fully seated.
