EMERGENCY OVERVIEW

RISK

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Not normally a hazard due to physical form of product.  Considered an unlikely route of entry in commercial/industrial environments.  

CHRONIC HEALTH EFFECTS

  Principal routes of exposure are usually by skin contact or eye contact with the material and inhalation of generated dust.  Prolonged or repeated skin contact may cause drying with cracking,irritation and possible dermatitis following.  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.  As with any chemical product, contact with unprotected bare skin; inhalation of vapor, mist or dust in work place atmosphere; or ingestion in any form, should be avoided by observing good occupational work practice.
