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.
