Exposure Controls/Personal Protection

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

Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.

Exposure Effects

Chronic inhalation or ingestion may cause argyria characterized by blue-gray discoloration of the eyes, skin and mucous membrances. Chronic skin contact may cause permanent discoloration of the skin.

Exposure limit(s)

TLV (as Mn): ppm; 0.2 mg/m3 (ACGIH 1995-1996).

Poison Class

4 (Substances and products that must be considered harmful)

Fire Fighting Measures

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Material will not burn. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.

Fire Potential

This material is probably combustible.

Accidental Release Measures

Small spills/leaks

Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity

Disposal Code

15

Incompatibilities

Can react with strong acid, strong oxidizing agents, powdered metals; may react violently with hydrogen peroxide.

Stability

Stable under normal temperatures and pressures.

Decomposition

Carbon dioxide, sulfur oxides (SOx), including sulfur oxide and sulfur dioxide, oxides of manganese.
