IV FIRE AND EXPLOSION HAZARDS DATA
Flash Point (Method Used): N/A Autoignition Temperature: No Data
Flammable Limits: Upper: N/A Lower: N/A
Extinguishing Media: Use suitable extinguishing media for surrounding materials and type of fire.
Special Fire Fighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes. Isolate runoff to prevent environmental pollution.
Unusual Fire and Explosion Hazards: When heated to decomposition, tantalum phosphide may emit toxic oxides of phosphorus. Reacts with water to slowly evolve phosphine gas.
V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of tantalum phosphide have not been thoroughly investigated and reported.
Tantalum compounds may cause skin and eye irritation.
Inorganic phosphorus compounds may cause irritation and hemorrhages in the stomach as well as liver and kidney damage. Bone structure may be attacked, especially the jaw and teeth. Phosphides are particularly dangerous because they tend to decompose to the very toxic phosphine upon contact with moisture or acids. Phosphines, if generated, is a very toxic, flammable gas. The chief effects are central nervous system depression and lung irritation. Inhalation can cause coma and convulsions leading to death within 48 hours.
Inhalation: May cause respiratory irritation.
Ingestion: May cause nausea, vomiting, abdominal pain and diarrhea.
Skin: May cause severe irritation to moist living tissue.
Eye: May cause severe irritation.
Chronic Effects: No chronic health effects recorded.
Target Organs: May affect the respiratory system
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory 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 medical attention if symptoms persist.
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: Immediately flush eyes, including under eyelids, with large amounts of water for at least 15 minutes. Seek medical attention if symptoms persist.
VI REACTIVITY DATA
Conditions to Avoid: Water/moisture
Incompatibility (Material to Avoid): Water/moisture
Hazardous Decomposition Products: Oxides of phosphorus and phosphine.
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 and provide ventilation. 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.
Waste Disposal: Dispose of in accordance with Local, State and Federal regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: NIOSH-approved dust-mist-vapor cartridge respirator.
Ventilation: Use local exhaust to maintain concentration at low exposure levels. Handle in a controlled environment. Handle under dry protective gas. General exhaust is recommended.
Protective Gloves: Rubber gloves.
Eye Protection: ANSI approved safety goggles.
Other Protective Gear: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Keep container tightly closed. Store in a cool, dry, well-ventilated area. Wash thoroughly after use. Handle under dry, protective gas. May react with water or acids to form phosphine gas which is toxic and flammable. Do not store together with acids. Store away from water/moisture. Protect from humidity and water. Store under dry inert gas.
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 hygienic facilities for washing.
