V HEALTH HAZARD INFORMATION
Health Hazards (Acute and Chronic):
To the best of our knowledge the chemical, physical and toxicological properties of manganese oxide have not been thoroughly investigated and recorded.
Manganese compounds can cause central nervous system and pulmonary system damage by inhalation of fumes and dust. Very few poisonings have occurred from ingestion. Chronic manganese poisoning is a clearly characterized disease which results from inhalation of fumes or dust of manganese. Exposure to heavy concentrations of dusts or fumes for as little as three months may produce the condition, but usually cases develop after 1-3 years of exposure. The central nervous system is the chief site of damage. Exposure to dusts and fumes can possibly increase the incidence of upper respiratory infections and pneumonia. Chronic manganese poisoning usually begins with complaints of languor and sleepiness. This is followed by weakness in the legs and the development of stolid, mask-like faces. The patient speaks with a slow monotonous voice. Then muscular twitching appears, varying from a fine tremor of the hands to coarse rhythmical movements of the arms, legs, and trunk. Nocturnal cramps of the legs appear about the same time. There is a slight increase in tendon reflexes, ankle and patellar clonus, and typical Parkinsonian slapping gait (Sax, Dangerous Properties of Industrial Materials, eighth edition).
Acute Effects:
Inhalation: May cause irritation of the respiratory tract, mucous membranes and metal fume fever.
Ingestion: Absorption of manganese compounds from the gastrointestinal tract is poor under normal conditions.
Skin: May cause irritation. Danger through skin absorption.
Eye: May cause irritation.
Chronic Effects:
Inhalation: May cause pulmonary pneumonitis, manganism, psychic and neurological disorders effecting the central nervous system.
Ingestion: No chronic health effects recorded.
Skin: May cause dermatitis.
Eye: Irritant salts may cause conjunctivitis damage.
Medical Conditions Generally Aggravated By Exposure: It has been recorded that when exposed to manganese dust and fumes, there is a higher incidence of upper respiratory infection and pneumonia compared to general population.
Routes of Entry: Inhalation, eyes, skin.
Target Organs: May affect the central nervous system, kidneys, respiratory system and liver.
Carcinogenicity: NTP: No IARC Monographs: No OSHA Regulated: No
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and SEEK MEDICAL ATTENTION IMMEDIATELY.
INGESTION: Give 1-2 glasses of water or milk and induce vomiting; SEEK MEDICAL ATTENTION. Never induce vomiting or give anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing; brush material off skin; wash affected area with soap and water. Seek medical attention.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.
VI REACTIVITY DATA
Stability: Stable
Incompatibility (Material to Avoid): None
Hazardous Decomposition Products: Manganese fume.
Hazardous Polymerization: Will not occur
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wearing suitable respiratory protection and protective clothing. Isolate spill area, provide ventilation and extinguish sources of ignition. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust. Use non-sparking tools.
Waste Disposal Method: Consult Local, State and Federal regulations for proper disposal of manganese.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH/MSHA approved respirator for dusts, fumes, and mists.
Ventilation: Use local exhaust to maintain concentration at or below the PEL, TLV. Mechanical exhaust is not recommended.
Eye Protection: Safety glasses
Protective Gloves: Impervious gloves
Other Protective Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Keep container tightly sealed. Store in cool, dry place in tightly closed containers. Ensure good ventilation at the workplace.
Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and smoking. Do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
