EMERGENCY OVERVIEW

RISK

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.  The material is.  discomforting.  to the gastrointestinal tract.  Ingestion may result in nausea, abdominal irritation, pain and vomiting.  if swallowed in large quantity.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  There is some evidence to suggest that this material can causeeye irritation and damage in some persons.  The dust may produce eye discomfort causing smarting, pain and redness.  Direct eye contact with some anionic surfactants in high concentration can cause severe damage to the cornea. Low concentrations can cause discomfort, excess blood flow, and corneal clouding and swelling. Recovery may take several days.  

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 be.  slightly.  discomforting.  to the skin.  from repeated exposures over long periods.  and may be capable of causing allergic skin reactions.  Repeated skin contact with some sulfonated surfactants has produced sensitization dermatitis in predisposed individuals.  

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.  The dust may be discomforting.  to the upper respiratory tract.  Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis, may incur further disability if excessive concentrations of particulate are inhaled.  

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.  

  Principal routes of exposure are by accidental skin and eye contact andinhalation of generated dusts.  Prolonged or repeated skin contact may cause drying with cracking,irritation and possible dermatitis following.  As with any chemical product, contact with unprotected bare skin; inhalation of vapor, mist or dust in work place atmosphere; or ingestion in any form, should be avoided by observing good occupational work practice.
