Storage of Flammable
Refrigerant Cylinders
•
Ensure that the storage facility has a fire
suppression system approved for use with
flammable refrigerants. At a minimum, a Dry-
Powder Fire Extinguisher rated for Class B fires
must be located near the storage area and the
facility should have emergency action and fire
prevention plans. Note that flammable gas fires
should not be extinguished until the source of the
burning gas has been shut off.
•
Ensure the storage area is well-ventilated.
•
Ensure the storage area is free of combustible or
waste materials.
•
Ensure all areas used for storage of flammable
gas containers comply with all federal, provincial,
state and local requirements.
•
NEVER
store refrigerant cylinders near sources
of ignition.
•
NEVER
re-use or re-fill aftermarket service
cylinders.
•
Protect gas cylinders from impact, falling or being
knocked over. Ensure that any accompanying
protective caps/covers are in place.
•
Keep refrigerant cylinders out of the sun and
away from sources of heat. Cylinders should be
stored in cool, dry areas where the temperature
does not exceed 125 deg. F or 52 deg. C.
•
Secure refrigerant cylinders to prevent theft or
tampering.
•
Never fill refrigerant recovery cylinders beyond
the maximum capacity.
•
Use appropriate markings and labeling on
refrigerant recovery cylinders. This includes
flammable material symbols and possible
additional color markings.
•
Storage facilities should consider installing
combustible gas detection systems in accordance
with federal, provincial, state and local
requirements.
Transport of Flammable
Refrigerant Cylinders
•
Ensure that a Dry-Powder Fire Extinguisher rated
for Class B fires is available on the vehicle.
•
Transport of flammable refrigerant cylinders must
be in accordance with federal, provincial, state
and local requirements.
•
DO NOT
store flammable refrigerant cylinders
near heat or a source of ignition.
•
Store the cylinders for transport in accordance
with US Department of Transportation and
Transport Canada requirements. Mark flammable
refrigerant cylinders with a red “FLAMMABLE
GAS” graphic as prescribed by U.S. 49 CFR part
172.417.
•
Prior to loading and transport, close the main
cylinder valve and remove any regulator valve.
Ensure that any accompanying protective caps/
covers are also in place.
•
Place cylinders with flammable refrigerant
in a well-ventilated area. For enclosed
vehicles, transport cylinders or canisters in
accordance with US DOT and Transport Canada
requirements. Service companies/technicians
should consider, where appropriate, that storage
cabinets be externally vented as an additional
measure of safety.
•
Secure flammable refrigerant cylinders to prevent
theft, tampering, or movement during transport.
