2.8 Safety regulations
Refrigerant data
Toxicity
Low
Contact with skin
If sprayed, the refrigerant is likely to cause frost burns. If absorbed by the
skin, the danger is very limited; it may cause a slight irritation, and the
liquid is degreasing. Unfreeze the affected skin with water. Remove the
contaminated clothes with great care - in the presence of frost burns, the
clothes may stick to the skin. Wash with plenty of warm water the affected
skin.
In the presence of symptoms such as irritation or blisters, obtain medical
attention.
Contact with eyes
Ingestion
Inhalation
Recommendations
Prolonged exposure
Vapours do not cause harmful effects. The spraying of refrigerant may
cause frost burns. Wash immediately with a proper solution or with tap
water for at least 10 minutes, and then obtain medical attention.
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.
R410A: remarkable concentrations in the air may have an anaesthetic
effect, up to fainting. The exposure to considerable amounts may cause
irregular heartbeat, up to the sudden death of the patient. Very high
concentrations may result in the risk of asphyxia, due to the reduction in
the oxygen percentage in the atmosphere. Remove the patient to fresh air
and keep warm and at rest.
If necessary, give oxygen. In case of breathing difficulties or arrest, pro-
ceed with artificial respiration. In case of cardiac arrest, proceed with
cardiac massage. Then, obtain 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.
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.
