Hazardous classification
Classified as dangerous goods according to the ADG Code
Not classified as hazardous according to criteria of NOHSC.
Specific hazards
Rapid evaporation of the liquid may cause frostbite.
Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing.
4. FIRST AID MEASURES
General advice : If unconscious place in recovery position and seek medical advice. Never give
anything by mouth to an unconscious person. If breathing is irregular or
stopped, administer artificial respiration. If symptoms persist, call a physician.
Inhalation : Move to fresh air. Keep patient warm and at rest. Artificial respiration and/or
