CANADIAN WHMIS SYMBOLS

EMERGENCY OVERVIEW

RISK

Harmful if swallowed.
May cause SENSITIZATION by skin contact.
May cause harm to the unborn child.

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.  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

  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

  There is some evidence to suggest that this material, if inhaled, can irritate the throat and lungs 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 of vapor is more likely at higher than normal temperatures.  

CHRONIC HEALTH EFFECTS

  Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.  Ample evidence exists, from results in experimentation, that developmental disorders are directly caused by human exposure to the material.  

  The primary routes of exposure are usually by skin contact/absorption  inhalation of fumes. Soldering fumes pose special problems as composition  and concentration of pyrolysis products is complex and variable. Mechanical  controls to minimise worker exposure are recommened.  Soldering with this product releases irritating formaldehyde in rosin fume.  Soldering with this product may release aniline - a potential carcinogen.  WARNING: Limited animal studies have indicated that aniline hydrochloride  may be a potential carcinogen and therefore extreme care should be exercised  when handling this product. [IARC]  WARNING: Dimethylformamide presents an exposure hazard to pregnant women.  Females of child bearing potential should avoid airborne exposure above the  TLV and avoid skin contact.  NTP Carcinogenesis studies; Laboratory assigned Jan. 1988.  [RTECS]  Removal of contact lenses after an eye injury should only be undertaken by  skilled personnel.
