EMERGENCY OVERVIEW

RISK

Very toxic to aquatic organisms, may cause long- term adverse effects in the
aquatic environment.

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.  

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).  

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.  

INHALED

  Inhalation may produce health damage*.  There is some evidence to suggest that this material, if inhaled, can irritate the throat and lungs of some persons.  

CHRONIC HEALTH EFFECTS

  For standard operation (eg. milling, cutting and grinding)  aluminium should be treated as a nuisance dust. Periodic medical  examinations are recommended for personnel regularly exposed to aluminium  fines, including a chest X-ray.  Exposure to zinc oxide fume subsequent to burning, welding, molten metal  work, etc. can result in "zinc chills" (metal fume fever). The temporary  symptoms can include fever, chills, nausea, vomiting, and muscular pain.  Onset of symptoms occurs about 4-12 hours after exposure. Recovery is  usually complete in 24 to 48 hours.  Exposure to dust/fines presents a low health risk by inhalation. The  WORKSAFE limits for nuisance dust are applicable.
