Section 2 - HAZARDS IDENTIFICATION

CANADIAN WHMIS SYMBOLS

EMERGENCY OVERVIEW

RISK

May cause SENSITIZATION by skin contact.
Limited evidence of a carcinogenic effect.
Toxic: danger of serious damage to health by prolonged exposure through
inhalation and if swallowed.
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

  There is some evidence to suggest that this material can causeeye irritation and damage in some persons.  

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

  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.  

CHRONIC HEALTH EFFECTS

  There has been concern that this material can cause cancer or mutations, but there is not enough data to make an assessment.  Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.  

  Primary route of exposure is usually by inhalation.  Inhalation will occur if dust is generated. Dust/fines of aluminium, carbon  and mild steel are low health risks by inhalation but cryolite is more  hazardous. Prolonged or excessive inhalation of the dust may result in  fluoride decomposition in bones and teeth (fluorosis), and may be  accompanied by stiffness of the joints. Overexposure to metal fumes which  only occur when the material is heated to very high temperatures, may cause  upper respiratory tract irritation, nausea and metal fume fever. Chronic  inhalation of excessive levels of fine powder may cause pulmonary fibrosis and  emphysema. For personnel habitually exposed to dust, annual measurement of  urinary fluoride is recommended. [ILO Encyclopaedia, Alcoa]  WARNING:  Some of the materials have been classified by IARC as follows-  Group 1- nickel, nickel II oxide; Group 2B-lead; Group 3-  chromium VI oxide  and chromium III oxide. Worker exposure by all routes should be carefully  monitored and kept to a minimum.
