Fire Fighting Measures

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.

Accidental Release Measures

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 and Reactivity

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.

Stability

Stable at room temperature in closed containers under normal storage and handling conditions.

Decomposition

Oxides of sulfur, irritating and toxic gases.
