Applications
Chlorofluorocarbon (CFC) refrigerants controlled under the Montreal Protocol; production and consumption have been phased out worldwide. They now exist only under essential-use exemptions, as feedstocks and in reclaimed form, mainly for servicing existing equipment.
Safety & storage
Store in a cool, dry, well-ventilated place away from heat and open flame; keep cylinders upright and secured against rolling or impact. Although non-flammable, avoid high temperature that raises cylinder pressure.
