SECTION 3 PRECAUTIONARY LABEL INFORMATION
WARNING: CONTAINS MANGANESE - AVOID INHALING DUST
Chronic exposure to heavy concentrations of manganese
containing dust can cause central nervous system disorders.
SECTION 4 FIRST AID INFORMATION
INHALATION: Remove to fresh air. Treat symptoms. Support breathing as required. Call a physician.
EYES: Immediately flush for at least 15 minutes while holding eyelids open to ensure no
particles remain in the eye. If symptoms such as irritation develop, consult a physician.
SKIN: Wash thoroughly with mild soap and water. A shower is recommended if significant dust
exposure occurs.
INGESTION: If swallowed and the person is conscious, drink water and induce vomiting. Call a
physician.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Exposure may aggravate pre-existing respiratory infections. Persons with a history of alcoholism, psychiatric,
neurologic, pulmonary, or liver disease may be at a greater risk of developing symptoms of over exposure.
NOTE: After first aid, seek prompt, professional medical attention.
NOTE TO PHYSICIAN: Based on the individual reactions of the patient, the physician's judgement should be
used to control symptoms and clinical condition.
CAUTION: If unconscious, having trouble breathing or in convulsions, do not induce vomiting or give water.

SECTION 6 HEALTH EFFECTS INFORMATION
PRIMARY ROUTE(S) OF EXPOSURE: INHALATION
TARGET ORGAN EFFECTS: LUNGS/PULMONARY FUNCTION, CENTRAL NERVOUS SYSTEM
SYMPTOMS OF OVER EXPOSURE TO MANGANESE:
ACUTE (Short Term Effects)
Over exposure can cause mild to moderate irritation to skin, eyes, nose and throat depending on the duration
of contact. Redness and tearing of eyes and red, dry skin are possible. Inhalation can result in pulmonary
effects, consisting of difficult, shallow respiration and fever which mimics metal fume fever as well as cold-like
symptoms (chills and muscle aches, dryness of the mouth).
CHRONIC (Long Term Effects)
Chronic exposure can result in conjunctivitis from irritant dusts and dermatitis. Chronic inhalation of manganese
containing dust can result in Central Nervous System disorders that may appear after 6 months to 2 years of
elevated exposure. The symptoms, which resemble Parkinsons Disease, are described below:
Stage I (subclinical/reversible): Indifference; irritability; headache; anorexia; sleep disturbances; decreased
libido; arthralgia; muscular spasm and diminished fine motor coordination; emotional and behavioral disorders
called "manganic psychosis" are more frequently seen among miners at this stage.
Stage II (clinical/intermediate): Speech becomes slow and stammering with monotonous voice; mask-like
faces; excessive salivation; awkward gestures; tremors of tongue, arms, and legs; gait disturbances.
Stage III (late): Muscular rigidity; bradykinesia with slow spasmodic gait; emotional instability; postural
instability and imbalance; diminished mental ability.

SECTION 7 TOXICOLOGY INFORMATION
Specific toxilogical information for Manganous Oxide is not available.
Manganese Dioxide
iv LD50 (rabbit) = 45 mg/kg
Manganese Compounds as Manganese (Mn)
Oral LD50 (rat) = 9000 mg/kg
LD50 = Lethal dose which leads to death of 50% of a population.
CARCINOGENICITY: Manganese is not listed by NTP, IARC, OSHA or EPA as carcinogenic.
SECTION 8 FIRE AND EXPLOSION INFORMATION
FLASH POINT: Not Flammable
STABILITY: Stable
HAZARDOUS POLYMERIZATION: Will not occur
EXTINGUISHER MEDIA: Dry chemical, Carbon dioxide or water extinguishers
suitable.
OTHER HAZARDS: See incompatibility below.
SECTION 9 REACTIVITY INFORMATION
INCOMPATIBILITY:
Reacts violently with strong oxidizers such as H2 O2 , F2 , Ca(OCl)2 , and organic peroxides.
Also, manganese is a transition metal and could function as a catalyst for other reactions.
THERMAL DECOMPOSITION PRODUCTS:
None. Manganous Oxide will, at high temperatures, and in the presence of air, react to form higher manganese
oxides such as Mn3 O4 , liberating heat.

SECTION 10 PERSONAL PROTECTION EQUIPMENT
RESPIRATORY PROTECTION:
Where airborne concentrations may exceed OSHA/ACGIH permissible air concentrations, the minimum
respiratory protection recommended is a negative pressure air purifying respirator with cartridges that are
NIOSH/MSHA approved against dust, fume, and mists having a TWA not less than 0.05 mg/cubic meter.
A general dust mask is recommended for applications where airborne concentrations are below the regulatory
limits.
VENTILATION: General ventilation is recommended.
PROTECTIVE EQUIPMENT:
Safety glasses or goggles are recommended where the possibility of getting dust particles in eyes exists.
Gloves or other protective clothing recommended if skin contact is appreciable.
If clothing is contaminated, remove clothing and thoroughly wash the affected area. Launder contaminated
clothing before reuse.
The availability of an eye wash fountain and safety shower is recommended.
SECTION 11 SPILL AND DISPOSAL INFORMATION
IN CASE OF TRANSPORTATION ACCIDENTS, CALL THE 24-HOUR CHEMTREC HOTLINE (800) 424-9300.
SPILL CONTROL AND RECOVERY:
Use clean-up procedure that minimizes exposure to dust. Vacuuming is preferred for dust. Use of approved
respirators is required for applications where adequate ventilation cannot be provided. Place all material in a
closed container if dry. Refer to CERCLA in Section 13.
DISPOSAL:
Dispose of in accordance with applicable federal, state, and local regulations.
