V HEALTH HAZARD INFORMATION
Health Hazards (Acute and Ch ronic):
To the best of our knowledge the chemical, physical and toxicological properties of manganese oxide have not been
thoroughly investigated and recorded.
Mang anese comp oun ds can cau se cen tral nervou s system and pulm ona ry system dam age by in halatio n of fum es and du st.
Very few poiso ning s hav e occ urred from in gestion. Ch ronic mang anese po isonin g is a clearly characterized disease w hich results
from inhalation of fumes or dust of manganese. Exposure to heavy concentrations of dusts or fumes for as little as three months may
produc e the cond ition, but usu ally cases develop after 1-3 years of ex posure. T he ce ntral nervo us system is the ch ief site of dam age.
Exp osure to d usts and fu mes can po ssibly increase the inciden ce of up per respirato ry infection s and p neum onia. Ch ronic m anganese
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 E ffects:
Inhalation: May cau se irritation of the respiratory tract, mucous m emb ranes and m etal fume fever.
Ingestion: Absorption of m anganese co mp ounds from the gastrointestinal tract is poor un der no rmal condition s.
Skin : May cause irritation.
Eye: May cause irritation.
Chro nic 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 ex posed to mangan ese dust an d fum es,
there is a higher incidence of upper respiratory infection and pneumonia compared to general population.
Routes of Entry: Inhalation, Eyes, Ingestion.
Target Organs: May affect the central nervous system, kidney s, respiratory system and liver.
Carcino genicity: NTP: No IARC M onographs: No OSH A Regulated: No
EMERG ENCY 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 M EDICAL AT TENTION . Never induce vomiting or
give anything by mouth to an unconscious person.
SK IN: 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
Haz ardous D ecomposition Produc ts: Manganese fume.
Hazardous Polymerization: Will not occur
VII SPILL OR LEAK PROC EDURES
Steps to Be Taken in Case Material Is Released or Spilled: We aring suitable respiratory protection and protective clothing. Iso late
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 co ntainer for p roper d isposal. Tak e care no t to raise dust. Use n on-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/M SHA appro ved respirator for dusts, fumes, and m ists.
Ventilation: Use local exhaust to maintain concentration at or below the PEL, TLV. Mechanical exhaust is not recommended.
Eye Protection: Safety glasses
-Manganese Oxide 2-
Protective Gloves: Any glo ve to prev ent skin contact.
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.
Wo rk Practices: Imp lem ent en gineering and wo rk practice controls to re duc e and ma intain c onc entration o f exp osure 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.
