APPENDIX: SAFETY DATA R-410A
Refrigerant Data
Safety Data: R-410A
Toxicity
Low
Contact with Skin
Liquid spatters can cause freeze burns.
It is impossible skin absorption could result dangerous. It can be slightly
irritating. Liquid has a degrease effect. Defrost with water the affected zones.
Take off carefully contaminated clothing, since it could have been sticked on
the skin in case of frostbite. Wash up affected zones plenty of lukewarm water.
If irritations or blister formation occur, get medical attention.
Contact with Eyes
Vapors cause harmful effects. Liquid splashes can cause freeze burns.
Immediately flush with an ophthalmic solution or with lukewarm clear water for
at least 10 minutes. Seek medical attention as soon as possible.
Ingestion
Very unlikely - should something happen, it will cause frost burns. Do not induce
vomiting. Only if the patient is conscious, wash out mouth with water and give
some 250 ml of water to drink. Then, obtain medical attention.
Inhalation
R-410A: High concentration levels in the air can cause an anesthetic effect,
including loss of consciousness. Exposure to extremely elevated dosages can
be unexpectedly lethal.
There is risk of suffocation at higher concentrations due to the oxygen content
reduction at the atmosphere. Remove victim to fresh air, keep it warm and at
rest. Supplemental oxygen if it is necessary.
If breathing has stopped or is labored, give assisted respirations. In case of
cardiac arrest apply severe assisted massage. Get medical attention
immediately.
Medical Attention
Semiotics or support therapy is recommended. Cardiac sensitization has been
observed that, in the presence of circulating catecholamines such as adrenalin,
may cause cardiac arrhythmia and accordingly, in case of exposure to high
concentrations, cardiac arrest.
Prolonged Exposure
R-410A: a study on the effects of exposure to 50,000 ppm during the whole life
of rats has identified the development of benign testicle tumor.
This situation should therefore be negligible for personnel exposed to
concentrations equal to or lower than professional levels.
Occupational Exposure Limits
R-410A: Recommended threshold: 1000 ppm v/v - 8 hours TWA.
Stability
R-410A: no specific data.
Conditions to Avoid
Do not use in the presence of high temperatures, flames, burning surfaces and
excess humidity.
Hazardous Reactions
A violent reaction can be occurred by contact with sodium, potassium, barium
and other alkaline metals. Incompatible substances: magnesium and more than
2% magnesium alloys.
Hazardous Decomposition
Products
R410A: Halogen acids produced by thermal decomposition and hydrolysis.
