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 suddenly 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.
