Personal Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.

Respirators
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

Exposure limit(s)
TLV (as Sn): ppm; 0.1 mg/m3 (skin) (ACGIH 1992-1993).

Poison Class
3

Flash Point
81-83

Autoignition
100

Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Do NOT get water inside containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of water until well after fire is out.

Fire Potential
Combustible material: may burn but does not ignite readily.

Small spills/leaks
Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Provide ventilation. Stop leak only if you can do so without risk.

Disposal Code
15

Stability
Stable under normal temperatures and pressures.

Incompatibilities
Strong oxidizing agents.

Decomposition
Carbon monoxide, carbon dioxide, tin/tin oxides.

Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
