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.  

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.  

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.  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

  Primary route of exposure is usually by inhalation of generated dust.  Long term exposure to high dust concentrations may cause changes in lung function i.e. pneumoconiosis; caused by particles less than 0.5 micron penetrating and remaining in the lung. Prime symptom is breathlessness; lung shadows show on X-ray.  Used, fired refractory materials are potentially more harmful than new refractories. Chromite containing materials when exposed to high temperatures in oxidising furnaces may be converted or part converted to chromium VI compounds, i.e. chromates; these materials present an increased hazard for skin contact or if present in inhaled dust. Chromates are recognised as carcinogens and have a much lower Exposure Standard than chromite, i.e. chromium III compounds. Exposure to fired refractories is more likely when rebricking, repairing, rebuilding and demolishing old furnaces. Chromates are water soluble and hence may be spread if water spray is used to suppress dust.
