!
• When refrigerant HFC-134a (R-134a) strike
your eye(s), consult a doctor immediately.
• Do not use your hand to rub affected
eye(s). Instead, use quantities of fresh cold
water to splash it over affected area to thus
gradually raise its temperature above the
freezing point.
• Obtain proper treatment as soon as
possible from a doctor or eye specialist.
Should liquid refrigerant HFC-134a (R-
134a) get on your skin, such affected part
should be treated in the same manner as
when skin is frostbitten or frozen.
