R407C

Low

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 conta-

minated 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 vomit-

ing. 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.

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 pres-

ence 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: 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 occupa-

tional limits or equal to them.

R407C: Recommended limits: 1,000 ppm v/v – 8 hours TWA.

R407C: Not specified.

R407 C: Halogen acids deriving from thermal decomposition and hydrolysis.

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.
