APPENDIX: SAFETY DATA R410A
Refrigerant data
Safety data: R410A
Toxicity
Low
Contact with Skin
R410A vapours 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.
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. Then, obtain medical attention.
Inhalation
Inhalation of the R410A vapour may cause irritation. Vapour 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: is stable under normal operating conditions.
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. Specific
materials to avoid include freshly abraded aluminium surfaces and active
metals such as sodium, potassium, calcium, powdered aluminium,
magnesium and zinc.
Hazardous Decomposition
Products
R410A: Halogen acids produced by thermal decomposition and hydrolysis.
