MATERIAL SAFETY DATA

SAFETY DATA

R407C

Toxicity

Low.

In contact with skin

Liquid splashes or spray may cause freeze burns. Unlikely to be hazardous by skin absorp-
tion. Thaw affected areas with water. Remove contaminated clothing carefully – may
adhere to skin in case of freeze burns. Wash affected areas with plenty of warm water. If
symptoms occur (irritation or blistering) obtain medical attention.

In contact with eyes

Vapor has no effect. Liquid splashes or spray may cause freeze burns. Immediately
irrigate with eyewash solution or clean water for at least 10 minutes. Obtain immediate
medical attention.

Ingested

Highly unlikely to occur – but should this occur freeze burn will occur. Do not induce
vomiting. Provided patient is conscious, wash mouth with water and give about 250 ml (0.5
pint) to drink. Obtain immediate medical attention.

Inhalation

High atmospheric concentrations may have an anaesthetic effect, including loss of con-
sciousness. Very high exposures may cause an abnormal heart rhythm and prove suddenly
fatal.
At higher concentration there is a danger from asphyxiation due to reduced oxygen content
of atmosphere. Remove patient to fresh air, keep warm and at rest. Administer oxygen if
necessary. Apply artificial respiration if breathing has ceased or shows signs of failing. In
event of cardiac arrest apply external cardiac massage. Obtain immediate medical attention.

Further medical

Symptomatic and supportive therapy is indicated. Cardiac sensitization has been described

advice

which may, in the presence of circulating catecholamines such as adrenaline, give rise to
cardiac arrhythmia’s and subsequent arrest following exposure to high concentrations.

Long-term exposure

A lifetime inhalation study in rats has shown that exposure to 50,000 ppm resulted in benign
tumors of the testis. This is not considered to be of relevance to humans exposed to
concentrations at or below the occupational exposure limit.

Occupational

Recommended limit: 1000 ppm v/v - 8 hr TWA.

exposure limits
Stability

Not specified.

Conditions to avoid

Use in presence of naked flames, red hot surfaces and high moisture levels.

Hazardous reactions

May react violently with sodium, potassium, barium and other alkali and alkaline earth
metals. Incompatible materials: Magnesium and alloys containing more then 2% magnesium.

Hazardous

Halogen acids by thermal decomposition and hydrolysis.

General precautions

Avoid inhalation of high concentrations of vapors. Atmospheric concentrations should be
minimized and kept as low as reasonably practicable below the occupational exposure limit.
The vapor is heavier than air and collects at low level and in confined areas. Ventilate by
extraction at lowest levels.

Respiratory protection Where doubt exists on atmospheric concentration, HSE approved breathing apparatus

should be worn. This should be self contained or of the long breather type.

Storage

Keep containers dry and in a cool place away from fire risk, direct sunlight, and all sources
of heat such as radiators. Keep at temperatures not exceeding 45°C.

Protective clothing

Wear overalls, impervious gloves and goggles/face protection.

Spill/leak procedure

Ensure suitable personal protective clothing and respiratory protection is worn. Provided it is
safe to do so, isolate the source of the leak. Allow small spillage’s to evaporate provided
there is suitable ventilation.
Large spillages: Ventilate area. Contain spillage’s with sand, earth or any suitable absorbent
material. Prevent liquid from entering drains, sewers, basements and work pits since vapor
may create a suffocating atmosphere.

Disposal

Best to recover and recycle. If this is not possible, destruction is to be in an approved facility
which is equipped to absorb and neutralize acids and other toxic processing products.

Fire extinguishing

Non-flammable at atmospheric conditions.

Containers

Fire exposed containers should be kept cool with water sprays. Containers may burst if
overheated.

Fire fighting

Self contained breathing apparatus and protective clothing must be worn in

protective equipment fire conditions.
