the body.
NOTE: Do not store corrosive materials in these units. Any damage
which occurs due to storage of corrosives will not be covered under
warranty claims.
Corrosive Materials Requiring Refrigerated or Frozen Storage
•Only use models rated as Corrosion Resistant
•Corrosion Resistant does not mean Corrosion Proof – Care in
storage is still required
•Store only corrosive reagents/samples which truly need
reduced temperature storage.
•Flammable corrosive materials require Flammable Material Storage
or Explosion Proof models labeled for the storage of corrosives
•Containers must be wiped clean of moisture and chemical
residue before being introduced into the unit and upon return
from use.
•Containers must be sealed with either vinyl tape or Parafilm ®
•Reagents/samples which release HX (X= F, Cl, Br, I) on contact
with moisture (e.g. Acyl halides, Organosilyl halides etc.) are
particularly damaging to metals.
•Volatile amines will react with HX depositing salts which will
lead to corrosion of metal surfaces.
•Volatile organic acids can exacerbate metal surfaces
already compromised, be sure these are securely sealed.
•Refrigerated compartments are cool or cold areas but they are not
to dry seal your reagents and samples.
•Bleach solutions release chlorine gas which can react with
other volatiles in the cooling chamber or directly attacks metal
surfaces.
•Periodically clean the interiors, clean up spills or leaking containers
•Failure to take precautionary actions may lead to damage not
covered by warranty claims

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 if work areas are designated
as a hazardous location with respect to the presence of flammable gases or
vapors. Such locations are defined in (National Fire Protection Association) 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 been
evaluated by Underwriters
Laboratories (UL) 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 are ideal 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.
WARNING: For FMS and EXP units where flammable materials are
stored in the cooling chamber, the cooling chamber is considered a
Class I Div1 or Class I Zone 1 hazardous location. Any monitoring
devices placed in the cooling chamber must have an intrinsically
safe rating from an appropriate certification body, such as UL,
CSA, FM etc. (this includes battery or solar powered devices).
Thermocouples for building monitoring systems must be wired
through an electrical barrier designed to provide isolation against
voltage and current spikes, which could cause a spark resulting in
fire or explosion. It is the end user's responsibility to meet these
requirements. Thermo Scientific cannot assist with the selection of
devices, recommend, approve or design any device or monitoring
circuit.
*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 for use in Class I, Division 1, Groups C
and D environments, which require an Explosion- Proof
Refrigerator/Freezer.
FMS units are designed and evaluated by Underwriters Laboratories (UL)
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 are ideal 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 durable
enamel finish. Interiors have epoxy enamel or ABS plastic construction.
Each unit is insulated throughout for energy-efficient operation.
WARNING: For FMS and EXP units where flammable
materials are stored in the cooling chamber, the cooling
chamber is considered a Class I Div1 or Class I Zone 1
hazardous location. Any monitoring devices placed in the
cooling chamber must have an intrinsically safe rating
from an appropriate certification body, such as UL, CSA, FM
etc. (this includes battery or solar powered devices).
Thermocouples for building monitoring systems must be wired
through an electrical barrier designed to provide isolation against
voltage and current spikes, which could cause a spark resulting
in fire or explosion. It is the end user's responsibility to meet
these requirements. Thermo Scientific cannot assist with the

How to Seal Junction 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 top and bottom hubs of the vertical conduit. The
fiber rope da m ns w
ill surround con
duit wiri ng t hat is hous ed
inside the vertical condu it.
When both the top and bottom fiber rope dams have been
pressed into place, sealing compound is poured between the
two and form s into an airtight plu g.
All of thi
s is done in order to preve
nt the very real threat of
gas entering the junction box and a resulting serious
explosion.
After the unit wir es hav e be en pu
l led throu
gh the vertical
conduit the following procedure is required:
•Turn power o
ff at the cir
cui t breaker before
proceeding.
•Place a sm
all amount of sealing compound
granules, enclosed, into a clean mixing vessel. Add
s m all am ounts of w ater whil e stirring un til a thick
