Physical properties of refrigerant HFC-134a
Avoid contact with liquid refrigerant HFC-134a. At atmospheric pressure HFC-134a
evaporates at approximately -26 °C and causes frost bite.
After skin contact, rinse the affected area with water.
After eye contact, rinse the eye(s) with plenty of water for at least 15 minutes and
consult a doctor.
HFC-134a must not be allowed to escape in enclosed areas. Although HFC-134a is
not toxic, there is a danger of suffocation as gaseous refrigerant is heavier than air.
Please observe the following first aid instructions. After inhalation, move the
affected person to fresh air, keep him warm and allow him to rest. If necessary, he
should be supplied with oxygen. If he has stopped breathing or is breathing
erratically, he should be given artificial respiration. In the case of cardiac arrest,
carry out heart massage. Send for a doctor immediately.
Moreover, it must be noted that HFC-134a must always be extracted from the
system and collected. It must never be discharged into the atmosphere on
environmental grounds (greenhouse effect).
