Health Hazard Data and First Aid
Short term effects of over exposure when:
In contact with skin:
Liquid splashes may cause freeze burns. No information found on irritancy or
sensitisation. There is no known hazard due to absorption through the skin.
In contact with eyes: Liquid splashes or vapour spray may result in freezing of tissue or eye fluids.
Inhaled: Very high concentrations may produce anaesthetic effects and can act as an
asphyxiant by limiting available oxygen. They also may prove suddenly fatal
(cardiac sensitisation).
10 min effective concentration 50 28% (Rat)
15 min lethal concentration 50 > 80% (Rat)
4 hr lethal concentration 50 > 50% (Rat)
Threshold for cardiac sensitisation 7.5% 5 min (Dog)
Ingested: Extremely unlikely to occur under normal industrial use.
Should this occur freeze burns will result.
Long term effects of over exposure:
No effects have been seen in rats exposed to up to 50,000 ppm for 90 days. It is not teratogenic in rats or
rabbits. Short-term screening tests for carcinogenicity have proved negative. No long-term effects were noted
when administered by gavage to rats at a dose of 300 mg/kg/day for one year and the rats held for the
remainder of their life span.
Occupational Exposure Limit (OEL):
1000 ppm v/v – 8 hr TWA value.
Emergency and First Aid Procedures:
Skin:
Thaw affected areas with water, remove contaminated clothing carefully, wash affected areas
of skin thoroughly with copious amounts of warm water. If symptoms occur, obtain medical
attention.
Eyes: Irrigate with eyewash solution or clean water for at least 10 minutes. Obtain immediate
medical attention.
Inhalation: Remove patient to fresh air, keep warm and at rest, administer oxygen if necessary. Apply
artificial respiration if breathing has ceased. Apply external cardiac massage in the event of
cardiac arrest. The use of adrenaline or similar sympathomimetic drug should be
avoided. Obtain immediate medical attention.
Ingestion: Highly unlikely. Should this occur freeze burns will result.
Further Medical Advice
Symptomatic and supportive therapy as indicated. Cardiac sensitisation has been described which may, in
the presence of circulating catecholamines such as adrenaline, give rise to cardiac arrythmias and
subsequent arrest following exposure to high concentrations of vapour. Therefore, adrenaline and similar
sympathomimetic drugs should be avoided.
Spill or Leak Procedures
Steps to be taken in event of Spill or Release
Shut off leak if without risk. Allow spilled liquid to evaporate. Contain spillage with sand or earth, prevent
liquid entering sewers, basements and pits since vapour may create suffocating atmosphere.
Neutralising Chemicals
None necessary.
Disposal Procedures
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.
