V HEALTH HAZARD INFORMATION
Effects of Over Exposure:
To the best of our knowledge the acute and chronic toxicity of molybdenum carbonyl has not been thoroughly investigated and reported.
Acute molybdenum poisoning may cause severe gastrointestinal irritation, diarrhea, coma and death from cardiac failure. Chronic molybdenum poisoning in laboratory animals has caused loss of weight, anorexia, anemia, deficient lactation, male sterility, osteoporosis and bone joint abnormalities.
Carbonyl compounds are toxic due to decomposition yielding carbon monoxide. Symptoms include asphyxia, headache, mental confusion, dizziness, impairment of vision and hearing, and fainting. High exposures can result in unconsciousness and death due to the inability of hemoglobin to carry oxygen to the tissues.
Acute Effects:
Inhalation: Toxic by inhalation.
Ingestion: Toxic by ingestion.
Skin: Irritating to skin and mucous membranes
Eye: Irritating
Carcinogenicity: No data found
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove to fresh air. If required, provide artificial respiration. Keep patient warm; seek immediate medical advice.
INGESTION: Do not induce vomiting. Immediately call for medical help. Seek immediate medical advice.
SKIN: Immediately wash with soap and water and rinse thoroughly. Seek immediate medical advice.
EYE: Flush with water for at least 15 minutes, including under eyelids. Consult a doctor.
V REACTIVITY DATA

VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wear protective equipment. Keep unprotected persons away. Ensure adequate ventilation. Sweep up, place in a bag and hold for waste disposal. Avoid raising dust. Use sand or vermiculite.
Waste Disposal Method: Dispose of in accordance with all State, Federal and Local regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: NIOSH/MSHA approved filter - dust, fume, mist. Use suitable respirator when high concentrations are present.

IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Handle under dry protective gas. Keep container tightly sealed. Store in a cool, dry place in tightly closed containers. Ensure good ventilation at the workplace. Open and handle container with care.
Other Precautions: Store under dry inert gas. Protect from heat and direct sunlight. Keep container tightly sealed. Store in cool, dry conditions in well sealed containers. Store under lock and key and with access restricted to technical experts or their assistants only. Store away from oxidizing agents. Do not store together with alkalies (caustic solutions). Store away from halogens. Flammable. Keep ignition sources away. Protect from heat.
Work Practices: The usual precautionary measures for handling chemicals should be followed. Keep away from foodstuffs, beverages and feed. Remove all soiled and contaminated clothing immediately. Wash hands before breaks and at the end of work. Store protective clothing separately. Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
