environment.

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.  

SKIN

  Not normally a hazard due to physical form of product.  

INHALED

  Not normally a hazard due to non-volatile nature of product.  Exposure to fumes of tin oxide produce a benign pneumoconiosis without fibrosis or evidence of silicosis. The fact that there appears to be little respiratory disability is unexpected in view of the gross radiological abnormalities. Deposited particles are nodular and appear to be extracellular. No necrosis, foreign body giant-cell reaction or collagen formation is evident.  

CHRONIC HEALTH EFFECTS

  Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems.  Chronic exposure to tin dusts and fume can result in substantial amounts being deposited in the lungs and result in reduced lung function and difficulty breathing.  Metallic dusts generated by the industrial process give rise to a number of potential health problems. The larger particles, above 5 micron, are nose and throat irritants. Smaller particles however, may cause lung deterioration. Particles of less than 1.5 micron can be trapped in the lungs and, dependent on the nature of the particle, may give rise to further serious health consequences.  Exposure relates to handling of molten metal in casting or machining of  formed bearings.  Periodic medical examination are advised for regular exposure to tin and  tin compounds with emphasis directed towards chest X-ray. [GENIUM]
