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.  The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  The material can produce chemical burns to the eye following direct contact. Vapors or mists may be extremely irritating.  If applied to the eyes, this material causes severe eye damage.  The material may be irritating to the eye, with prolonged contact causing inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  The material can produce chemical burns following direct contactwith the skin.  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

  If inhaled, this material can irritate the throat andlungs of some persons.  Inhalation of vapor is more likely at higher than normal temperatures.  The material may produce respiratory tract irritation, and result in damage to the lung including reduced lung function.  

CHRONIC HEALTH EFFECTS

  Principal routes of exposure are via eye and skin contact and  inhalation.  Eye contact with the material will cause pain and possible burns with a  resulting vision impairment which may be temporary or permenent depending on  the severity of exposure.  Skin contact will result in pain and reddening of the skin with chemical  burns resulting from more severe exposures.  Inhalation of concentrated vapours or mist may cause severe pain and burning  sensation in the nose and throat.  Ingestion of the liquid will produce pain in the mouth, throat and  oesophagus. Symptoms of ingestion may include nausea, vomiting, abdominal  pain and diarrhoea.
