POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Although ingestion is not thought to produce harmful effects, the material may still be damaging to the health of the individual following ingestion, especially where pre-  existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  Although the material is not thought to be an irritant, direct contact with the eye may produce transient discomfort characterized by tearing or conjunctival redness (as with windburn).  The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  The material is not thought to produce adverse health effects or skin irritation following contact (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin.  

INHALED

  The material is not thought to produce adverse health effects or irritation of the respiratory tract (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting.  Inhalation hazard is increased at higher temperatures.  

CHRONIC HEALTH EFFECTS

  There is some evidence that inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population.  There is sufficient evidence to suggest that this materialdirectly causes cancer in humans.  

  Principal routes of exposure are usually by inhalation of vapour and  skin/eye contact. Inhalation may cause headache, dizziness and nausea.  Inhalation of high concentrations for prolonged periods may result in acute  toxic effects such as respiratory difficulty, convulsions, possible  cardiovascular collapse and unconsciousness. Contact with skin can result in  irritation which when not washed off or when accentuated by sunlight or ultra-  violet radiation, can result in photosensitisation and minor burns.  Ingestion may cause nausea and vomiting, abdominal discomfort, rapid pulse.  Cardivascular collapse may occur. Long term exposure to vapours or liquid may  cause cancer of lungs or skin. Warts may appear on the skin after prolonged  exposure. They may or may not be cancerous.  WARNING : Coal tar is classified by IARC as Group 1 - CARCINOGENIC TO HUMANS.  Coal tar pitch pitch volatiles are classified by Worksafe as Category 1 -  Established Human Carcinogen, by ACGIH as A1 - CONFIRMED HUMAN CARCINOGEN  and by IARC as Group 1 - CARCINOGENIC TO HUMANS.
