SAFETY DATA FOR R-410A
Toxicity
Low
Skin Contact
Splashes of liquid may cause frostbite.. It is unlikely that skin absortion dangerous; It can
be irritating and the liquid has a degreasing effect. Thaw affected areas with water.
Remove contaminated clothing carefully because it may stick to the skin in the case of
burns caused by freezing. Wash the affected areas with warm water. If irritation or
blistering symptoms appears then get medical attention.
Eyes contact
Vapors cause harmful effects. Splashes of liquid may cause frostbite. Wash immediately
with an ophthalmic solution or clean running water for at least 10 minutes and get medical
attention immediately.
Ingestion
Very unlikely to happen, but if it happened would occur freeze burns. Do not force the
patient to vomit. If the patient is conscious, wash out mouth with water and give to drink
250 ml of water; Get medical attention immediately.
Inhalation
R410A: remarkable concentrations in the air may have an anesthetic effect,
unconsciousness. Exposure to extremely high doses may be suddenly fatal. At higher
concentrations there is a danger of suffocation due to the reduction of oxygen content in
the atmosphere. Remove patient to fresh air and keep warm and at rest. Administer
oxygen if necessary. Apply artificial respiration if the patient has stopped breathing or
shows signs of it. In the case of cardiac arrest apply external cardiac massage. Get
immediate medical attention.
Medical Advice
This is a semiotics and supportive therapy. We observed a cardiac sensitization that can,
in the presence of circulating catecholamines such as adrenaline, cause cardiac
arrhythmias and subsequent arrest of the heart after exposure to high concentrations .
Prolonged exposure
R410A: An inhalation lifelong study on rats showed that exposure to 50,000 ppm resulted
in benign tumors of the testis. This is not considered important for humans who have been
exposed to at or below the occupational exposure limit concentrations
Occupational exposure limits
R410A: Recommended limits: 1,000 ppm v / v - 8 hours Weighted Average.
Stability
R410A: No specification
Avoiding Conditions
Do not use in the presence of outdoor flames, hot surfaces and high humidity levels.
Dangerouse reactions
It can produce a violent reaction with sodium, potassium, barium and other alkali metals.
Incompatible substances: magnesium and alloys containing more than 2% magnesium.
Harmful decomposition products
R410A: Halogen acids by thermal decomposition and hydrolysis.
