SECTION 3: Hazards Identification
Emergency Overview: May be irritating to eyes, skin and respiratory tract. May be harmful if swallowed. Some managanese compounds are known to affect the central nervous system. Possible risk of irreversible effects.
Primary Routes of Exposure: Inhalation and Ingestion
Eye Contact: May cause slight to mild irritation of the eyes.
Skin Contact: May cause slight to mild irritation of the skin.
Inhalation: Vapor or mist may be irritating to the nose, mucous membranes and respiratory tract, and cause chronic health problems.
Ingestion: No information available on the physiological effects of ingestion.
Acute Health Effects: May be irritating to skin, eyes and respiratory tract.
Chronic Health Effects: Prolonged exposure to manganese containing dust may produce manganese pneumonitis and manganese poisoning. Symptoms include sleepiness, weakness and emotional disturbances. Equivocal studies have shown manganese may decrease fertility in men. Possible risk of irreversible damage.
NTP: No
IARC: No
OSHA: No
SECTION 4: First Aid Measures
Eye Exposure: Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure: Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation: Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion: Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.
SECTION 5: Fire Fighting Measures
Flash Point: no data
Autoignition Temperature: no data
Explosion Limits: no data
Extinguishing Medium: carbon dioxide, foam or dry powder
Special Fire Fighting Procedures: If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self- contained breathing apparatus and full protective clothing.
Hazardous Combustion and Decomposion Products: If involved in a fire this material may emit irritating fumes.
Unusual Fire or Explosion Hazards: Highly flammable. Formation of explosive air/vapor mixtures is possible.
SECTION 6: Accidental Release Measures
Spill and Leak Procedures: Small spills can be mixed with vermiculite, sodium carbonate or other suitable non combustible adsorbent and swept up.
SECTION 7: Handling and Storage
Handling and Storage: Keep material in a tightly sealed container. Prolonged exposure to the air or moisture will result in degradation of the product. Handle and store material under an inert atmosphere of nitrogen or argon.
SECTION 8: Exposure Controls and Personal Protection
Eye Protection: Always wear approved safety glasses when handling a chemical substance in the laboratory.
Skin Protection: Wear protective clothing and gloves. Consult with glove manufacturer to determine the proper type of glove.
Ventilation: If possible, handle the material in an efficient fume hood.
Respirator: If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection: No additional protection required.
