Safety data
Not important
Splashes or sprinkles can cause frostbite. The risk of absorptions through the skin
is not relevant..
Those refrigerants could take some lightly irritating effects and in liquid stage they
have a strong skinning effect. In this case it is necessary to rinse with fresh water
the contaminated parts of the skin.
The refrigerant in liquid stage in contact with wet clothes cause freezing and
adherence to the skin. In this case it is necessary to put off the contaminated
clothes to avoid freezing. Please contact a doctor in case of irritation of the
contaminated parts.
Vapors don't take any effect. Splashes or sprinklers can cause frostbite. In those
cases it is necessary to rinse the eyes with water or with solution for ocular
washings for 10 minutes. The intervention of a doctor is needed.
Should it happen, it causes frostbite. It does not cause vomiting. The person must
be kept awake. It is needed to rinse the mouth with fresh water and to drink
almost 0,25 liters. The intervention of a doctor is needed.
High concentration of vapours in air can lead to anaesthetic effects up to a loss of
conscience. Long exposures could give rise to cardiac arrhythmia and sometimes
even to death.
High concentrations can create a reduction of oxygen in air, with consequent
possibility of suffocation. Should it happen the person must be taken to the open
air and let him to take a rest.
Administer oxygen if needed. In case the breathing has interrupted or become
irregular, it is necessary to do artifi cial breathing. In case of cardiac arrest a heart
massage must be applied. Contact a doctor immediately.
Use in presence of exposed fl ames, and of high levels of humidity.
Possibility of violent reactions with sodio, potassio, barium and with other alkaline
substances, Incompatible materials and all the alloys containing more than 2% of
magnesium.
Wear protection apparel and self respirators. Insulate the source of the loss, if this
operation can be done in safety conditions. Small quantitative of refrigerant escaped
at liquid state can be allowed to evaporate only if the room is well ventilated. In
case of great losses ventilate the room immediately. Plug the loss with sand, soil
or other absorbent material; avoid that the liquid refrigerant can enter in water-
drainages or losing pools.
The best procedure is refrigerant recovery and recycling. If this is not possible the
refrigerant must be conferred to an accredited system for its destruction in order
to neutralize acid and toxic by-products.
