Explosion-Proof Refrigerators and
Freezers
Overview
Conventional refrigerators and freezers are not suitable for storing
flammable materials. Such units have components in their
electrical and refrigeration systems that can trigger explosions of
flammable air-vapor mixtures inside the unit and/or in the
immediate surrounding area.
The Authority Having Jurisdiction (AHJ) determines ifwork areas
are designated as a hazardous location with respect tothe
presence of flammable gases or vapors. Such locations are
defined in(National Fire Protection Agency) NFPA 70 Articles 500-
501 and OSHA 29 CFR1910.307. Some of these classified areas
are expected to experience concentrations of flammable gases
and/or vapors at or above their lower flammability limits for
extended periods of time.
The construction of our explosion-proof units has beenevaluated
by Canadian standards Association (CSA) and are suitable for use
in classified areas requiring Class I,Groups C and D* protected
equipment. The electrical components such as thermostats, wiring,
splices, relays and compressor motors on explosion-proof units are
safely housed within explosion-proof enclosures and conduit.
Compressor surface temperatures have been evaluated and
determined to remain below the flash point of materials found in
Class I,Groups C and D.
All models have heavy-gauge, rigid, steel construction with a
durable enamel finish. Interiors have epoxy enamel or ABS plastic
construction. Each unit is insulated throughout for energy-efficient
operation.
These units areideal for storing cyclopropane, ethyl ether,
ethylene, acetone, alcohol, benzene, butane, gasoline,hexane,
lacquer solvent vapors, naphtha, natural gas or propane along
with many other potentially hazardous materials.
*The notation Class I, Groups C and D is an accepted abbreviation
for Class I,Div 1, Groups C and D; Class I Zone 1 Group IIB.

Flammable Materials
Storage Refrigerators and
Freezers
Overview
Conventional refrigerators and freezers are not suitable for
storing flammable materials. Such units have components in
their electrical and refrigeration systems that can trigger
explosions of flammable air-vapor mixtures inside the unit.
Flammable Materials Storage (FMS) refrigerators/freezers are
designed for use in locations, which are not classified by the
Authority Having Jurisdiction (AHJ) as hazardous. Under normal
operating conditions the build up or presence of flammable
vapors will not occur in the environment external to the unit.
(Commonly known as “Ordinary Locations”)
FMS units are NOT designed foruse inClass I,Groups
Cand D environments, which require anExplosion-
Proof Refrigerator/Freezer.
FMS units are designed and evaluated by Canadian standards
Association (CSA) to meet the requirements of the National Fire
Protection Association Standards Nos. 45, 70 and 99. These
units have no internal electrical components that could trigger an
explosion or fire of hazardous materials inside the unit.
These units areideal for storing cyclopropane, ethyl ether,
ethylene, acetone, alcohol, benzene, butane, gasoline, hexane,
lacquer solvent vapors, naphtha, natural gas or propane along
with many other potentially hazardous materials.
All models have heavy-gauge, rigid, steel construction with a

INSTALLATION
How to Seal Killark® Box Conduit with Fiber and
Sealing Compound to Help Protect Against
Explosions (Explosion-Proof Units Only):
The purpose of the procedure that follows is to build fiber rope
dams on the left and right hubs of the horizontal conduit. The
fiber rope damns will surround conduit wiring that is housed
inside the horizontal conduit.
When both the left and right fiber rope dams have been
pressed into place, sealing compound is poured between the
two and forms into an airtight plug.
All of this is done in order to prevent the very real threat of
gas entering the Killark box and a resulting serious explosion.
After the unit wires have been pulled through the horizontal
conduit the following procedure is required:
•Turn power off at the circuit breaker before proceeding.
•Place a small amount of sealing compound granules,
enclosed, into a clean mixing vessel. Add small amounts of
water while stirring until a thick paste isformed, then
carefully continue adding smaller amounts of water until a
thick gravy consistency is achieved—NOT WATERY.
Discard any material that becomes too stiff to use. Never
attempt to restore workability by stirring in more water.
•Locate silver Killark box, back/top-center of unit.
•Unscrew conduit domed-cover.

INSTALLATION
Figure 2: Horizontal Conduit, Cutaway
•Insert fiber rope material down into horizontal conduit opening. Pressing down firmly, work the
material into the left hub and—most importantly—being sure the material COMPLETELY
SURROUNDS THE WIRING, from the top to the bottom, completely blocking this end of the
horizontal conduit.
•Insert fiber rope material down into horizontal conduit opening. Pressing down firmly, work the material
into the right hub and—most importantly—being sure the material COMPLETELY SURROUNDS THE
WIRING, from the top to the bottom, completely blocking this end of the horizontal conduit.

16
INSTALLATION
•Pour sealing compound down inbetween the two fiber rope dams filling the remaining space. Pour slowly,
being careful not to trap air bubbles. Immediately wipe off any spilled sealing compound.
•Screw conduit domed-cover back onto conduit opening.
NOTE: INITIAL SETUP OF SEALING COMPOUND WILL OCCUR IN APPROXIMATELY 30
MINUTES HOWEVER, THE SEALING COMPOUND REQUIRES A MINIMUM OF 8 HOURS ABOVE
32ºF TO DEVELOP SUFFICIENT STRENGTH TO WITHSTAND EXPLOSIONS.
