Unusual Fire and Explosion Hazards:  Reacts with water to form ammonia, a fire and explosion hazard.

V.  HEALTH HAZARD INFORMATION 

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of aluminum nitride have not been thoroughly investigated and reported.

Aluminum may be implicated in Alzheimer's disease.  Inhalation of aluminum containing dusts may cause pulmonary disease.  Aluminum compounds have many commercial uses and are commonly found in industry.  Many of these materials are active chemically and thus exhibit dangerous toxic and reactive properties.

The details of the toxicity of nitrides as a group are unknown.  (Sax, Dangerous Properties of Industrial Materials, eighth edition)

Acute and Chronic Effects:  May be irritating to eyes, skin, and mucous membranes.

EMERGENCY AND FIRST AID PROCEDURES:

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

INGESTION:  Remove from exposure.  Seek prompt, competent medical attention.

SKIN:  Remove any contaminated clothing.  Flood skin with large volumes of water for 15 minutes.  Seek medical advice.

EYES: Flush with copious amounts of water for at least 15 minutes.  Then consult a doctor.

VI.  REACTIVITY DATA

Stability:  Stable

Conditions to avoid:  Moisture

Incompatibility (Materials to Avoid):  Water/moisture, air, acids, oxidizing agents

Hazardous Decomposition Products:  Contact with water releases flammable gases; ammonia, nitrogen oxides.

Hazardous Polymerization:  Will not occur.

VII.  SPILL OR LEAK PROCEDURES 

Steps to be Taken in Case Material is Released or Spilled:  Wearing full protective clothing and respiratory protection, eliminate all sources of ignition.  Cover spill with dry sand or dry vermiculite, mix well and carefully transfer to a well-marked container.  Close container tightly.  Submit or retain for disposal.

Waste Disposal Method:  Consult state, Local, and federal regulations for proper disposal of aluminum nitride.

VIII.  SPECIAL PROTECTION INFORMATION
