Hazards and Protection.
Storage
Do not store in direct sunlight. Store in a cool, dry area away from incompatible substances.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Minimize dust generation and accumulation. Do not get on skin or in eyes. Do not ingest or inhale. Do not allow contact with water.
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.

Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation.
Stability
Stable at room temperature in closed containers under normal storage and handling conditions.
Incompatibilities
Alkalis, carbonates (soluble), gold salts, lead acetate, lime water, potassium, potassium iodide, Silver salts, sodium borate, sodium tartrate, tannin. Substance oxidizes when in contact with moisture to form ferric sulfate.
Decomposition
Oxides of sulfur, irritating and toxic gases.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Use extinguishing media appropriate to the surrounding fire. Substance is noncombustible. Decomposes at high temperatures, resulting in toxic and corrosive products. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. Use water spray, dry chemical, or foam.
Fire potential
Substance is noncombustible. Decomposes at high temperatures, resulting in toxic and corrosive products.
Hazards
Some may burn but none ignite readily. May polymerize explosively when heated or involved in a fire. Containers may explode when heated. Some may be transported hot.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.
