Safe Storage

Separated from strong oxidants.

Cleanup Methods

If tin ... /is/ spilled or leaked, the following steps should be taken: 1. Ventilate area of spill or leak. 2. Collect spilled or leaked material in the most convenient and safe manner for reclamation or for disposal ... Liquid containing inorganic tin compounds should be absorbed in vermiculite, dry sand, earth, or a similar material.

Disposal Methods

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Spillage Disposal

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.

Preventive Measures

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Eye Prevention

Wear safety goggles.

Fire Prevention

NO open flames.

Inhalation Risk

A harmful concentration of airborne particles can be reached quickly , especially if powdered.

Skin Prevention

Protective gloves.

Human Toxicity Excerpts

METALLIC TIN ... GENERALLY CONSIDERED OF LOW ORAL TOXICITY DUE TO ... POOR ALIMENTARY ABSORPTION.

Exposure to dust or fumes ... is known to cause a benign pneumoconiosis (stannosis). This form of pneumoconiosis produces distinctive progressive x-ray changes of the lung as long as exposure persists, but there is no distinctive fibrosis, no evidence of disability, and no special complicating factors.

Non-Human Toxicity Excerpts

... GUINEA PIGS SUBJECTED TO IP INJECTION OF SUSPENSION OF TIN DUST SHOWED THAT THE REACTION OF LUNG TISSUES WAS OF INERT TYPE. DUST WAS DEPOSITED IN PERITONEUM AS COLORED NODULES CONSISTING OF DARK PIGMENT MIXED WITH REFRINGENT CRYSTALS WHICH IN SOME CASES SEEM TO BE INCLUDED INSIDE MACROPHAGES, COMPARABLE TO "DUST CELLS" OF PULMONARY ANTHRACOSIS.

METALLIC TIN CAUSES NONSPECIFIC SMOOTH SURFACE CARCINOGENESIS IN EXPERIMENTAL ANIMALS WHERE SMALL TIN DISKS ARE IMPLANTED SUBCUTANEOUSLY OR INTRAMUSCULARLY.

RESULTS OF ANIMAL EXPERIMENTS INDICATE THAT ... INGESTION OF CONSIDERABLE QUANTITIES OF POWDERED TIN MAY CAUSE VOMITING BUT NOT PERMANENT INJURY.

Tin implanted as a particle of metal in the vitreous body of rabbits has been well tolerated for at least a year.
