Material Safety Data

Refrigerant Data:
Safety Data R407C
Toxicity Low.
In contact with skin Liquid splashes or spray may cause freeze burns. Unlikely to be hazardous by skin absorption.
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 Vapour 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 consciousness.
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 advice Symptomatic and supportive therapy is indicated. Cardiac sensitisation has been described which
may, in the presence of circulating catecholamines such as adrenalin, 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
tumours of the testis. This is not considered to be of relevance to humans exposed to
concentrations at or below the occupational exposure limit.
Occupational exposure Recommended limit: 1000 ppm v/v - 8 hr TWA.
limits
Stability Not specified.
Conditions to avoid Use in presence of naked flames, red hot surfaces and high moisture levels.
May react violently with sodium, potassium, barium and other alkali and alkaline earth metals.
Hazardous reactions
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 vapours. Atmospheric concentrations should be
minimised and kept as low as reasonably practicable below the occupational exposure limit. The
vapour 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 spillage's: Ventilate area. Contain spillage's with sand, earth or any suitable absorbent
material. Prevent liquid from entering drains, sewers, basements and work pits since vapour 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 neutralise acids and other toxic processing products.
Fire extinguishing data Non-flammable at atmospheric conditions.
Containers Fire exposed containers should be kept cool with water sprays. Containers may burst if
overheated.
Fire fighting protective Self contained breathing apparatus and protective clothing must be worn in fire conditions.
