• Avoid skin contact with refrigerants, as they
may cause frostbite.
• Never heat a container to temperatures higher
than 52°C (125°F).
• Never apply direct flame or live steam to a
container or valve.
• Never refill disposable cylinders with anything.
The shipment of refilled disposable cylinders is
prohibited by DOT regulations.
• Never refill returnable cylinders without DuPont
consent. DOT regulations forbid transportation
of returnable cylinders refilled without DuPont
authorization.
• Never use a lifting magnet or sling (rope or
chain) when handling containers. A crane may
be used when a safe cradle or platform is used
to hold the container.
• Never use containers as rollers, supports, or for
any purpose other than to carry refrigerant.
• Protect containers from any object that will result
in a cut or other abrasion in the surface of the
metal.
• Never tamper with the safety devices in the
valves or containers.
• Never attempt to repair or alter containers or
valves.
• Never force connections that do not fit. Make
sure the threads on the regulators or other auxil-
iary equipment are the same as those on the
container valve outlets.
• Keep valves tightly closed and valve caps and
hoods in place when the containers are not in use.
• Store containers under a roof to protect them
from weather extremes.
• Use a vapor recovery system to collect refrigerant
vapors from lines after unloading.
Recovery, Recycle,
Reclamation and Disposal
Responsible use of Suva
®
HP refrigerants requires
that the product be recovered for re-use or disposal
whenever possible. DuPont purchases used refrig-
erant for reclamation through its distributor net-
works in the United States, Canada and Europe.
In the United States, all Suva
®
HP products will
be accepted as part of this program. Recovery and
re-use of refrigerant makes sense from an environ-
mental and economic standpoint. In addition, the
U.S. Clean Air Act prohibits known venting of
CFC, HCFC, and HFC refrigerants during the
maintenance, servicing or disposal of refrigeration
equipment.
