Other hazards which do not result in classification

Vapours are heavier than air. Vapours may travel across the ground and reach remote ignition sources causing a flashback fire danger. May form flammable/explosive vapour-air mixture. This material is a static accumulator. Even with proper grounding and bonding, this material can still accumulate an electrostatic charge. If sufficient charge is allowed to accumulate, electrostatic discharge and ignition of flammable air- vapour mixtures can occur. This material is shipped under pressure. High gas concentrations will displace available air; unconsciousness and death may occur sud- denly from lack of oxygen. Exposure to rapidly expanding gases may cause frost burns to eyes and/or skin. Inhalation of vapours or mists may cause irritation to the respiratory system. Vapours may cause drowsiness and dizziness.
