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. This material has the potential to be a static accumulator. Electrostatic charges may be generated during pumping. Electrostatic discharge may cause fire. High gas concentrations will displace available air; unconsciousness and death may occur sud- denly from lack of oxygen. This product contains benzene which may cause leukaemia (AML - acute myelogenous leukae- mia). May cause MDS (Myelodysplastic Syndrome). Hydrogen sulphide (H2S), an extremely flammable and toxic gas, and other hazardous vapours may evolve and collect in the headspace of storage tanks, transport vessels and other enclosed containers. The classification of this material is based on OSHA HCS 2012 criteria.
