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

  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.  and may cause drying of the skin.  if exposure is prolonged.  Open cuts, abraded or irritated skin should not be exposed to this material.  The material may accentuate any pre-existing skin condition.  

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.  Inhalation hazard is increased at higher temperatures.  

CHRONIC HEALTH EFFECTS

  Ample evidence exists from experimentation that reduced human fertility is directly caused by exposure to the material.  Ample evidence exists, from results in experimentation, that developmental disorders are directly caused by human exposure to the material.  

  Principal routes of exposure are usually by skin contact and inhalation of vapor.  Prolonged or repeated skin contact may cause drying with cracking,irritation and possible dermatitis following.  The dried material contains quartz  Crystalline silicas activate the inflammatory response of white blood cells after they injure the lung epithelium. Chronic exposure to crystalline silicas reduce lung capacity and predispose to chest infections. A large part of the crystals accumulates in the lungs. Silicosis can occur, a condition where irreversible scarring of the lung occurs. Symptoms do not appear until months to years after exposure. Smoking increases this risk. Most simple cases of silicosis do not produce symptoms, but they can progress and eventually cause a tuberculosis-like syndrome which can be fatal. When silicosis is advanced, there is an increased risk of lung cancer and lymphoma. Laws in some areas require those exposed to silica to be under health surveillance.
