REMARKS
ACTION
Purge system with dry nitrogen
prior to soldering; refrigerant
heated by flame or hot surfaces
creates phosgene gas, a highly
toxic gas.
Do not let refrigerant touch
you or inhale refrigerant gas.
Be especially careful to pre-
vent refrigerant from coming
in contact with your eyes. In
case of refrigerant leaks,
ventilate area at once.
