IV.   FIRE AND EXPLOSION HAZARDS DATA

Flash Point:  N/A

Autoignition Temperature:  460 oC

Explosive LimitsLower:  N/A Upper:  N/A

Extinguishing Media:  DO NOT USE WATER.  Use class D or other metal extinguishing agent.

Special Firefighting Procedures:  Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.  Fumes from fire are hazardous.  Isolate runoff to prevent environmental pollution.

Unusual Fire and Explosion Hazard:  When heated to decomposition, titanium hydride may emit flammable hydrogen gas.  May have a violent reaction with oxidizing agents.  Titanium hydride dissociates above 288 oC and gradually evolves hydrogen gas.  Dust-air mixtures may be explosive.  Contact with water releases explosive hydrogen gas.

 

 

V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

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

Titanium compounds: There are no reported cases in the literature where titanium as such has caused human intoxication.  The dusts of titanium or most titanium compounds may be placed in the nuisance category.  (Sax, Dangerous Properties of Industrial Materials)

Acute Effects:

Inhalation:  Dust may cause irritation to the upper respiratory system.

Ingestion:  Ingestion of titanium hydride is considered non-toxic.

Skin:  Prolonged or repeated contact may cause irritation.

Eye:  Prolonged or repeated contact may cause irritation.

Chronic Effects:

Inhalation:  May cause slight lesions in the lungs.  No other chronic health effects recorded.

Target Organs:  No target organ effects recorded.

Medical Conditions Generally Aggravated by Exposure:  Pre-existing lung disorders.

Carcinogenicity:   NTP:  No      IARC:  No    OSHA:  No

 

EMERGENCY AND FIRST AID PROCEDURES:

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

INGESTION:  Give 1-2 glasses of milk or water and induce vomiting, seek immediate medical attention.  Never induce vomiting or give anything by mouth to an unconscious person.

SKIN:  Remove any contaminated clothing, brush material off of skin, wash with mild soap and water, seek immediate medical attention.

EYES:  Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek immediate medical attention.

 

 

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  None

Incompatibility (Materials to Avoid):  Oxidizing agents, acids, halogens, halocarbons, water/moisture.

Hazardous Decomposition Products:  Hydrogen gas

Hazardous Polymerization:  Will not occur

 

 

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled:  Wear appropriate respiratory and  protective equipment specified in section VIII.  Isolate 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 container for proper disposal.  Take care not to raise dust.  Use non-sparking tools.

Waste Disposal Method:  In accordance with Local, State and Federal Waste Disposal Regulations.

 

 

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH-approved dust, mist, fume respirator.

Ventilation:  Handle under dry argon.  Use local exhaust to maintain concentration at or below the PEL, TLV.  General exhaust is recommended.

Protective Gloves:  Rubber gloves

Eye Protection:  Safety glasses

Other Protective Clothing or Equipment:   Protective gear suitable to prevent contamination.

 

 

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Wash thoroughly after handling.  Do not get in eyes, or on skin or clothing.  Do not breath dust, vapor, mist, or gas.  Keep container closed.  Keep away from heat, sparks and open flame.  Store in a tightly closed container.  Do not store near combustibles.  Empty container may contain hazardous residues.  Flammable solid.  Keep material cool.  Handle under argon if possible as material can heat up and ignite during manipulation.

Other Precautions:  Store away from water/moisture.  Do not store together with acids.  Store away from halogens.  Store away from oxidizing agents.  Protect against electrostatic charges.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure 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.
