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

  This material can cause eye irritation and damage in some persons.  The material may be irritating to the eye, with prolonged contact causing 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.  Bare unprotected skin should not be exposed to this material.  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.  Although inhalation is not thought to produce harmful effects, the material may still produce health damage, especially where pre-existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally confined to doses producing mortality (death) rather than those producing morbidity (disease, ill-  health).  Inhalation hazard is increased at higher temperatures.  The material may produce respiratory tract irritation, and result in damage to the lung including reduced lung function.  

CHRONIC HEALTH EFFECTS

  The material is considered to be harmful by all exposure routes.  Bare unprotected skin should not be exposed to this material.  Principal routes of exposure are usually by skin contact, eye contact and inhalation of vapor.  Lead is a cumulative poison with adverse effects in pregnancy [NIOSHTIC].  Prolonged or repeated overexposure to low concentrations of acid vapour  may cause chronic bronchitis, corrosion of teeth, even chemical  pneumonitis.
