R134a
Low.
Liquid splashes or spray may cause freeze burns. Unlikely to be hazardous by skin absorption.
R134a may be slightly irritant and liquid has a degreasing effect. 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.
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.
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.
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.
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.
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.
Recommended limit: 1000 ppm v/v - 8 hr TWA.
Not specified.
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.
Incompatible materials: Magnesium and alloys containing more then 2% magnesium.
Halogen acids by thermal decomposition and hydrolysis.
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.
Where doubt exists on atmospheric concentration, HSE approved breathing apparatus should
be 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 such as radiators. Keep at temperatures not exceeding 45 °C.
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 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.
