SAFETY DATA
Toxicity Low.
Liquid splashes or spray may cause freeze burns. Unlikely to be hazardous by skin absorption. R22
may be slightly irritant and liquid has a degreasing effect. Thaw affected areas with water. Remove
In Contact With Skin
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.
Vapor has no effect. Liquid splashes or spray may cause freeze burns. Immediately irrigate with
In Contact With Eyes
eyewash solution or clean water for at least 10 minutes. Obtain immediate medical attention.
Highly unlikely to occur - but should this occur, freeze burn will occur. Do not induce vomiting.
Ingested Provided patient is conscious, wash mouth with water and give about 250 ml (0.5 pint) to drink.
Obtain immediate medical attention.
High levels of vapor concentration initially produce stimulation and then depression of the central
nervous system, causing headaches and giddiness and may lead to unconsciousness. Can prove
suddenly fatal if the exposure has been severe.
Inhalation 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.
Symptomatic and supportive theory is indicated. Cardiac sensitization has been described which

Medical Advice
and subsequent arrest following exposure to high concentrations.
A lifetime inhalation study in rats and mice gives a small excess in salivary gland tumors in male
Long-Term Exposure rats only at 50,000 ppm; 10,000 ppm showed no effect. This information suggests that R22 does
not represent a carcinogenic hazard to humans.
Occupational
Recommended limit: 1000 ppm v/v - 8 hr TWA 1250 ppm v/v - 12 hr TWA.
Exposure Limits
Stability Unstable.
Conditions to Avoid Use in presence of naked flames, red hot surfaces and high moisture levels.
May react violently with sodium, potassium, barium and all other alkali and alkaline earth metals.
Hazardous Reactions
Incompatible materials: Magnesium and alloys containing more than 2% magnesium.
Hazardous
Decomposition Halogen acids formed by thermal decomposition.
Products
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
General Precautions
heavier than air and collects at low level and in confined areas. Ventilate by extraction at lowest
levels.
Where doubt exists on atmospheric concentration, HSE-approved breathing apparatus should be
Respiratory Protection
worn. This should be self-contained or of the long breather type.
Keep containers dry and in a cool place away from fire risk, direct sunlight, and all sources of heat
Storage
such as radiators. Keep at temperatures not exceeding 45ºC (113ºF).
Protective Clothing Wear overalls, impervious gloves and goggles/face protection.
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 spillages to evaporate provided there is suitable
Spill / leak Procedure ventilation. Large spillages: ventilate area. Contain spillages 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.
Best to recover and recycle. If this is not possible, destruction is to be in an approved facility which
Disposal
is equipped to absorb and neutralize acids and other toxic processing products.
Fire Extinguishing Data Non-flammable.
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 fire conditions.
