POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  This material can cause eye irritation and damage in some persons.  The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  This material can cause inflammation of the skin oncontact in some persons.  Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through wounds, lesions or abrasions.  May be toxic if absorbed through the skin.  The material may cause severe 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. Repeated exposures may produce severe ulceration.  

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.  

CHRONIC HEALTH EFFECTS

  There has been concern that this material can cause cancer or mutations, but there is not enough data to make an assessment.  There is some evidence that inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population.  

  The primary route of exposure is via the skin and through inhalation.  Symptoms of over-exposure include mental confusion, light-headedness,  impaired judgement, nausea, vomiting, narcosis, unconsciousness and possible  death.  Methylene chloride causes liver and kidney damage in animals and this  justifies consideration.  Chronic overexposure to ethyl acetate may cause anaemia and  damage to liver and kidneys.  Asthma, bronchitis, allergies and other respiratory disorders may be  aggravated by exposure to isocyanate vapours.  Prolonged or repeated exposure may cause skin irritation and respiratory  and/or skin sensitization.
