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
Vapours 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 laboured, 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 tumour.
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 may occur if 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.
