Behaviour in case of fire
Never forget to wear protection clothes and breathing apparatus. Isolate the source of the leakage,
provided that this operation may be performed in safety conditions. Any small quantity of
refrigerant which may have escaped in its liquid state may evaporate provided that the room is
well ventilated.In case of a large leakage, ventilate the room immediately. Stop the leakage with
sand, earth or any suitable absorbing material. Prevent the liquid refrigerant from flowing into
drains, sewers, foundations or absorbing wells since its vapours may create an asphyxiating
atmosphere.
The best procedure involves recovery and recycle. If this is not possible, the refrigerant shall be
given to a plant which is well equipped to destroy and neutralise any acid and toxic by-product
which may derive from its disposal.
If they are exposed to the fire, they shall be constantly cooled down by water sprays.
Containers may explode if they are overheated.
In case of fire wear protection clothes and self-contained breathing apparatus.
R407C: Non flammable in the atmosphere.
R407C
Bas.
R407C: High concentration levels of its vapours in the air can produce an anaesthetic effect,
including the loss of consciousness. Particularly severe exposures may cause heart arrhythmia
and sometimes prove to be also fatal.
R407C: A lifetime study which has been conducted on the effects inhalation may have on rats at
50,000 ppm has shown the onset of benign tumours of the testicle. These remarks suggest that
there is no danger for human beings if they are exposed to concentrations below the occupational
limits or equal to them.
Liquid splashes or sprays may cause freeze burns. Unlikely to be hazardous by skin absorption.
However, R407C may be slightly irritant and, if liquid, it has a strong degreasing effect. Flush
contaminated skin areas with running water. If it comes into contact with wet fabrics, the liquid
refrigerant will cause them to freeze and adhere to the skin. Carefully remove the contaminated
clothing since it might adhere to the skin and cause freeze burns. Apply to a doctor if the affected
skin areas should be reddened or irritated.
Vapours have no effect. Liquid splashes or sprays may cause freeze burns. In these cases rinse your
eyes with running water or with a solution for eye lavages for at least 10 minutes. Immediately
apply to a doctor.
Very unlikely to occur. If this should be the case, it may cause freeze burns. Never induce vomiting.
Keep the patient awake. Make it rinse its mouth with running water and make it drink about
1/4 of a litre. Immediately apply to a doctor.
At high concentrations there is a danger of asphyxia due to a reduced oxygen content in the
atmosphere. In these cases take the patient to the open air, in a cool place and keep it at rest.
Administer oxygen, if required. Apply artificial respiration if breathing has ceased or if it has
become irregular. In case of heart failure immediately apply cardiac massage. Immediately
apply to a doctor.
In case of doubt about the actual concentration, wear breathing apparatus. It should be self-
contained and approved by the bodies for safety protection.
Refrigerant containers shall be stored in a cool place, away from fire risk, direct sunlight and all
heat sources, such as radiators. The maximum temperature shall never exceed 45°C in the storage
place.
Wear boots, safety gloves and glasses or masks for facial protection.
A symptomatic and supportive therapy is generally suitable. A heart sensitisation has been
observed in some cases, as a result of exposures to particularly high concentrations. In the
presence of catecholamines (such as for example adrenaline) in the blood flow, it has increased
the irregularity of the cardiac rhythm and then caused the heart failure.
Use in the presence of exposed flames, red heat surfaces and high humidity levels.
Possibility of violent reactions with sodium, potassium, barium and other alkaline substances.
Incompatible materials: magnesium and all the alloys containing over 2% of magnesium.
Avoid the inhalation of high concentrations of vapours. The concentration in the atmosphere
shall be kept at the minimum value and anyway below the occupational limits. Since vapours
are heavier than air and they tend to stagnate and to build up in closed areas, any opening for
ventilation shall be made at the lowest level.
R407C: Recommended limits: 1,000 ppm v/v
8 hours TWA.
R407C: Not specified.
R407 C: Halogen acids deriving from thermal decomposition and hydrolysis.
