EKWXA/EKWXBA
Causes
Safety data: R410A
Toxicity
Low
Contact with skin
R410A vapors can irritate the skin and eyes. In liquid form, it can freeze skin on contact. If
contact with skin occurs, flush the exposed area with lukewarm water until all of the
chemical is removed. If there is evidence of frostbite, bathe in lukewarm water.
Take off contaminated clothes carefully as they could be adhered to the skin in case of
frostbite burns. If there are irritation symptoms or blistering get medical attention.
Contact with eyes
If contact with eyes occurs, immediately flush with large amounts of lukewarm water for at
least 15 minutes, lifting eyelids occasionally to facilitate irrigation. 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. Seek medical attention immediately.
Inhalation
Inhalation of the R410A vapor may cause irritation. Vapor inhalation at high concentrations
may result in asphyxiation or the heart may become sensitized, causing cardiac
arrhythmia. When concentration of R410A reach levels which reduce oxygen to 14-16% by
displacement, symptoms of asphyxiation will occur. An individual exposed to high
concentrations of R410A must be given medical attention immediately. Adequate
ventilation must be provided at all times.
Recommendations
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
R410A: 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.
Professional levels
R410A: Recommended threshold: 1000 ppm v/v - 8 hours TWA.
Stability
R410A: without specification
Conditions to avoid
Do not use in the presence of high temperatures, flames, burning surfaces and excess
humidity.
Hazardous reactions
Contact with certain red-hot metals may result in exothermic or explosive reactions and
yield toxic and/or corrosive decomposition products.
Incompatible substances: magnesium and and alloys with more than 2% of magnesium.
Hazardous decomposition
products
R410A: Halogen acids produced by thermal decomposition and hydrolysis.
