Section 2 - HAZARDS IDENTIFICATION

CANADIAN WHMIS SYMBOLS

EMERGENCY OVERVIEW

RISK

May cause CANCER.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Considered an unlikely route of entry in commercial/industrial environments.  

INHALED

  Not normally a hazard due to non-volatile nature of product.  Inhalation hazard is increased at higher temperatures.  

CHRONIC HEALTH EFFECTS

  There is ample evidence that this material can be regarded as being able to cause cancer in humans based on experiments and other information.  

  High boiling residues of petroleum process can produce both benign and malignant skin tumors, according to animal testing. They may contain significant concentrations of polynuclear aromatic hydrocarbons (PAHs).  Repeated application of mildly hydrotreated oils (principally paraffinic), to mouse skin, induced skin tumors; no tumors were induced with severely hydrotreated oils.  Oil may contact the skin or be inhaled. Extended exposure can lead to eczema, inflammation of hair follicles, pigmentation of the face and warts on the soles of the feet. Exposure to oil mists can cause asthma, pneumonia and scarring of the lungs. Oils have been linked to cancer of the skin and scrotum. Compounds that are less viscous and with smaller molecular weights are more dangerous. There may be liver damage and the lymph nodes may be affected; heart inflammation can also occur at high doses.
