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

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

Unusual Fire & Explosion: When heated to decomposition, titanium nitride may emit toxic fumes of ammonia gas which can form explosive mixtures with air. Contact with acids may generate flammable hydrogen gas. May react with moist air to liberate ammonia gas.


Effects of Exposure:

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

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

The details of the toxicity of nitrides as a group are unknown. However, many nitrides react with moisture to evolve ammonia. This gas is an irritant to mucous membranes.

Acute Effects:

Inhalation: May cause irritation to the respiratory system and mucous membranes of the nose and throat. Ammonia gas may cause irritation to the nose and throat, dyspnea, bronchial spasms, chest pain, pulmonary edema and pink frothy sputum.

Ingestion: Considered to have low toxicity by ingestion. Ammonia gas may cause nausea, vomiting and burns.

Skin: May cause irritation. Ammonia gas may cause irritation and chemical burns.

Eye: May cause moderate irritation. Ammonia gas may cause severe irritation and chemical burns.

Chronic Effects:

Inhalation: May cause pulmonary edema. Repeated or prolonged exposure to ammonia gas may cause swelling of mouth and throat to the point of asphyxiation, permanent injury and death.

Ingestion: No chronic health effects recorded.

Skin: Repeated or prolonged exposure to ammonia gas may cause tissue damage.

Eye: Repeated or prolonged exposure to ammonia gas may cause irreversible damage to the conjunctiva, cornea and lens.

Routes of Entry: Inhalation, skin, eye.

Target Organs: May affect the respiratory system, skin and eyes.

Medical Conditions Generally Aggravated by Exposure: Pre-existing lung or skin conditions.

Carcinogenicity: NTP: No           IARC: No           OSHA: No


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

INGESTION: Do not induce vomiting, seek medical attention.

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

EYE: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes, seek medical attention.


Stability: Stable

Conditions to Avoid: Moisture, heat.

Incompatibility (Material to Avoid): Strong oxidizing agents, acids, water, steam, moisture.

Hazardous Decomposition Products: Oxides of nitrogen, ammonia gas, hydrogen gas.

Hazardous Polymerization: Will not occur


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. Scoop up or 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 Method: Dispose of in accordance with all Federal, State and Local Environmental Regulations.


Respiratory Protection: A NIOSH/MSHA approved dust respirator should be worn.

Ventilation: Handle in a controlled atmosphere. Handle under an inert gas such as argon. Use local exhaust to maintain concentration of exposure at low levels. General exhaust is not recommended.

Protective Gloves: Rubber gloves

Eye Protection: Safety goggles

Other Protective Clothing or Equipment: Chemically resistant clothing is recommended to minimize skin contact.


Precautions to Be Taken in Handling and Storage: Avoid breathing dust. Avoid getting in eyes or on skin. Wash thoroughly after handling. Store in a cool, dry place. Avoid contact with moisture. Reseal containers immediately after use. Store away from ignition sources and protect from electrostatic charges. Fumes can combine with air to form an explosive mixture.

Other Precautions: Titanium nitride may be moisture sensitive, handle and store under an inert gas such as argon.

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 or 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.
