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 artifi cial 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 limits Recommended limit: 1000 ppm v/v - 8 hr TWA.
Stability Not specifi ed.
Conditions to avoid Use in presence of naked fl ames, 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 decomposition products 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 confi ned areas. Ventilate by extraction
at lowest levels.
Respiratory protection Where doubt exists on atmospheric concentration, 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 fi re 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.
