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.  Considered an unlikely route of entry in commercial/industrial environments.  

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

  Skin contact with the material may damage the health of the individual; systemic effects may result following absorption.  The material is not thought to be a skin irritant (as classified using animal models). Temporary discomfort, however, may result from prolonged dermal exposures. Good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  Toxic effects may result from skin absorption.  

INHALED

  Inhalation may produce health damage*.  The material is not thought to produce respiratory irritation (as classified using animal models). Nevertheless inhalation of the material, especially for prolonged periods, may produce respiratory discomfort and occasionally, distress.  Inhalation of vapor is more likely at higher than normal temperatures.  

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.  

  The primary routes of exposure are by skin contact/absorption and  inhalation of fumes. Soldering fumes pose special problems as composition  and concentration of pyrolysis products is complex and variable. Mechanical  controls to minimize worker exposure are recommended.  Soldering with this product releases hydrazine, acrolein and hydrogen  bromide. All these materials are irritating and harmful.  Hydrazine, on which this material is based, is a suspected human carcinogen.  [ACGIH 1988-89]  Removal of contact lenses after an eye injury should only be undertaken by  skilled personnel.
