Flammable Limits:  Lower:  N/A      Upper:  N/A

Extinguishing Media:  Use suitable extinguishing media for surrounding material and type of fire.

Special Firefighting Procedures:  Firefighters should wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.

Unusual Fire and Explosion Hazards:  Flammable in the form of dust or powder which may ignite during intensive mechanical treatment.  When heated to decomposition, may emit toxic metal oxide fumes.

V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of Molybdenum TZM have not been thoroughly investigated and recorded.

Molybdenum dust and fumes (formed above 400 ^oC) can cause irritation of the eyes, nose, throat, and respiratory tract.  Molybdenum compounds are poison by subcutaneous and intraperitoneal routes.  Molybdenum and its compounds are highly toxic based upon animal experiments.  Symptoms of acute poisoning include severe gastrointestinal irritation with diarrhea, coma and deaths from heart failure.  Experimental animals exposed to high levels accumulated molybdenum in the lungs, spleen and heart, and showed a decrease of DNA and RNA in the liver, kidneys, and spleen.  (Sax, Dangerous Properties of Industrial Materials)

Titanium and titanium compounds are considered physiologically inert.  There are no reported cases in the literature in which titanium as such has caused human intoxication.

Inhalation of zirconium and zirconium compounds may cause pulmonary granulomas.

Acute Effects:

Inhalation:  May cause irritation to the upper respiratory system.

Ingestion:  May cause acute molybdenum poisoning.

Skin:  May cause irritation 

Eyes:  May cause irritation.

Chronic Effects:

Inhalation:  May cause pneumoconiosis, anemia, hyperthyroidism, abnormal liver function, increased susceptibility to gout.

Ingestion:  May cause chronic molybdenum poisoning.

Skin:  May cause irritation 

Eyes:  May cause irritation.

Medical Conditions Generally Aggravated by Exposure:  Pre-existing eye, skin or respiratory conditions.

Carcinogenicity:  NTP:  No     IARC:  No    OSHA:  No

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult.  Seek medical attention.

INGESTION:  Give 1-2 glasses of milk or water 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 mild soap and water, seek medical attention if symptoms persist.

EYE:  Flush eyes with lukewarm water, including under eyelids, for at least 15 minutes.  If irritation persists seek medical attention.

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  Protect dusts from sparks or ignition sources. 

Incompatibility (Material to Avoid):  Oxidizing agents, bromine trifluoride, chlorine trifluoride, fluorine, lead dioxide.

Hazardous Decomposition Products:  Metal oxide fumes.

Hazardous Polymerization:  Will not occur

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled (Applicable for Grinding Dust):  Wear appropriate respiratory and protective equipment specified in section VIII.  Ventilate area of spill.  Vacuum or sweep up material and place in appropriate container.  Avoid generation of dust.  After removal, flush contaminated area thoroughly with water.  Collect wash water for approved disposal.  Keep from entering water or ground water.

Waste Disposal Method:  Dispose of in accordance with Federal, State and Local regulations.

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH approved respirator if airborne dust concentrations exceed the TLV.

Ventilation:  Use local exhaust ventilation which is adequate to limit personal exposure to levels which do not exceed the PEL or TLV.  If such equipment is not available, use respirators as specified above.

Protective Gloves:  Chemically resistant gloves

Eye Protection:  Safety glasses or goggles

Other Protective Clothing or Equipment:  The usual precautionary measures for handling chemicals should be followed.

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Avoid formation of dusts.  Dust can combine with air to form an explosive mixture.  Avoid breathing dust, vapors, or mist.  Avoid contact with eyes.  Wash thoroughly after handling.  Store in a dry place away from excessive heat.  Avoid contact with moisture or water.  Reseal containers immediately after use.

Work Practices:  Maintain good housekeeping procedures to prevent accumulation of dust.  Use clean-up methods which minimize dust generation such as vacuuming or wet clean-up.  If airborne dust is generated, use an appropriate NIOSH approved respirator.  Wash thoroughly after handling and before eating or smoking and at the end of the work shift.  Do not shake clothing or other items to remove dust.  Use a vacuum.  Avoid dust inhalation and direct skin contact.  Do not ingest.

DOT Regulations:

Hazard Class:        None
