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 anaesthetic 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 sensitisation 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 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.
