Section 6: Accidental Release Measures


Small Spill:

Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.


Large Spill:

Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.


Section 7: Handling and Storage


Precautions: Do not breathe dust. Keep away from incompatibles such as oxidizing agents, acids.


Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area.


Section 8: Exposure Controls/Personal Protection


Engineering Controls:

Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.


Personal Protection: Safety glasses. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.  Gloves.


Personal Protection in Case of a Large Spill:

Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.

Ingestion: Oral toxicity is low.

No other toxicity information found for Manganese carbonate itself.



Manganese has low toxicity in acute exposure. Acute manganese poisoning is rare. The main route of occupational exposure is inhalation. There is low (10 percent) gastrointestinal absorption of manganese.

Manganese is mainly toxic to the central nervous system, producing psychiatric symptoms, dystonia, rigidity, decreased manual dexterity and gait disturbances.. It is mildly irritating to the eyes, skin and mucous membranes.

"Metal fume fever" can result from inhalation of manganese fumes. This flu-like condition includes fever, chills,

upset stomach, vomiting, weakness, headache, body aches, muscle pains, dry mouth and throat, coughing,

tightness of the chest, dyspnea and rales. Symptoms usually arise several hours after exposure, and subside in

a day.

A high incidence of pneumonia has been reported after exposure to manganese dust or fumes. "Manganese pneumonia" has been reported in mine workers. The clinical signs of this pneumonia are acute alveolar inflammation, marked dyspnea, shallow respiration and subsequent facial cyanosis. Exposure can cause pneumonitis and an increased susceptibility to infection Inhalation of manganese aerosols produced alternating movements, torpor, nervousness, tremor, yawning, and cyanosis in monkeys, followed by permanent neurological effects.


The target organs for chronic manganese exposure are the CENTRAL NERVOUS SYSTEM and LUNGS; chronic liver failure may also occur. The lowest exposure of manganese that will produce neurologic and pulmonary effects is not known. There are wide differences in susceptibility to manganese poisoning; the effects
