WABASCA HEAVY CRUDE OIL

SECTION 2: Hazards identification

This material is considered to be hazardous according to regulatory guidelines (see (M)SDS Section 15). POTENTIAL PHYSICAL / CHEMICAL EFFECTS Extremely flammable. Material can release vapors that readily form flammable mixtures. Vapor accumulation could flash and/or explode if ignited. Material can accumulate static charges which may cause an ignition.

Potential health effects

May cause cancer. Danger of adverse health effects by prolonged exposure. Repeated exposure may cause skin dryness or cracking. If swallowed, may be aspirated and cause lung damage. Under conditions of poor personal hygiene and prolonged repeated contact, some polycyclic aromatic compounds (PACs) have been suspected as a cause of skin cancer in humans. Hydrogen sulfide, a highly toxic gas, is expected to be present. Signs and symptoms of overexposure to hydrogen sulfide include respiratory and eye irritation, dizziness, nausea, coughing, a sensation of dryness and pain in the nose, and loss of consciousness. Odor does not provide a reliable indicator of the presence of hazardous levels in the atmosphere. May be irritating to the eyes, nose, throat, and lungs. Aliphatic hydrocarbon gases may build up in confined spaces and may cause dizziness, light-headedness, headache, nausea and loss of coordination. Continued inhalation may result in narcosis, unconsciousness, and possibly lead to death. May cause central nervous system depression. High-pressure injection under skin may cause serious damage. Exposure to benzene is associated with cancer (acute myeloid leukemia and myelodysplastic syndrome), damage to the blood- producing system, and serious blood disorders (see Section 11). Target Organs: Nervous system | Blood and/or blood-forming organs | Lung | Skin |

Environmental hazards

Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. NFPA Hazard ID: Health: 2 Flammability: 3 Reactivity: 0 HMIS Hazard ID: Health: 2* Flammability: 3 Reactivity: 0 NOTE: This material should not be used for any other purpose than the intended use in Section 1 without expert advice. Health studies have shown that chemical exposure may cause potential human health risks which may vary from person to person.
