Hazards and Protection.
Store in a cool, dry place. Keep container closed when not in use.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear safety glasses and chemical goggles if splashing is possible. Wear appropriate protective gloves and clothing to prevent skin exposure.
Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions.
While using the appropriate protective equipment, clean up spills immediately. Sweep up, then place into a suitable container for disposal.
Stable under normal temperatures and pressures. Gradually becomes light brown in air.
Strong oxidizing agents, strong acids.
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.
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. Use agent most appropriate to extinguish fire.

Effects include a parkinsonism-like syndrome, muscle weakness, impairment of speech, gait disturbances, tremor, slurred speech, diminished libido and behavioral disturbances. Symptoms may last 1 to 2 months or longer. Manganese injection has produced teratogenic effects in experimental animals, although ingestion and inhalation studies showed no effect. Manganese deficiency during gestation has demonstrated adverse effects on the central nervous system of the developing fetus in experimental animals.
Pleuritis and/or severe or fatal pneumonia have been reported among manganese workers. Metal fume fever has been reported after inhalation exposure to manganese oxide fumes.
Pleuritis and/or severe or fatal pneumonia have been reported among manganese workers.
Most exposures to manganese are chronic. Vomiting and activated charcoal may not be useful in chronic cases. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
Remove from exposure to fresh air immediately.
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids.
