Special Fire Fighting 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 & Explosion: When heated to decomposition, magnesium nitride may emit toxic fumes of magnesium oxide and ammonia. May be a moderate explosion hazard.






Routes of Entry: Inhalation, skin, eyes, and ingestion.


Health Hazards (acute and chronic):


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


              Magnesium compounds have variable toxicity. There is no evidence that magnesium produces true systemic poisoning. Protection necessary for personal handling and processing magnesium is usually no different from that which is necessary for other metals (Sax, Dangerous Properties of Industrial Materials, 8th ed.).


              Nitrides: The details of the toxicity of nitrides as a group are unknown. However, many nitrides react with moisture to evolve ammonia. The gas is an irritant to the mucous membranes (Sax, Dangerous Properties of Industrial Materials, 8th ed.).


              Ammonia gas is a human poison by an unspecified route. Poison by inhalation, ingestion, and possibly other routes. An eye, mucous membrane, and systemic irritant by inhalation. Mutation data reported (Sax, Dangerous Properties of Industrial Materials, 8th ed.).


Ingestion: Acute: Ammonia gas may cause nausea, vomiting and burns.

Chronic: No chronic health effects recorded.


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

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


Eyes: Acute: May cause irritation. Ammonia gas may cause severe irritation and possible chemical burns.

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


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

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


Carcinogenicity: NTP? No           IARC? No          OSHA Regulated? No

LD/LC50: No toxicity data recorded.


Signs and Symptoms of Exposure:


Inhalation: May cause coughing, sneezing, difficulty breathing, swelling of the mouth and throat.

Ingestion: May cause tissue damage, chemical burns, nausea and vomiting.

Skin: May cause redness, burning, inflammation, itching, blistering and tissue damage.

Eye: May cause redness, itching, burning, inflammation, watering, lens opacities, ulceration of the conjunctiva and cornea.




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.

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

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

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






Stability: Stable

Incompatibility (Material to Avoid): Water, moisture, strong acids and bases.


Hazardous Polymerization: Will not Occur

Hazardous Decomposition Products: Magnesium oxide and ammonia.







Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective equipment specified in Section VIII- Special Protection Information. 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 Method: Dispose of in accordance with Local, State and Federal regulations.

Hazard Label Information: Store in a cool, dry place. Store in a tightly sealed container. Wash thoroughly after handling.


Precautions to Be Taken in Handling and Storing/Other Precautions: Magnesium nitride evolves ammonia on contact with moisture and water. Handle and store in a controlled atmosphere and inert gas such as argon.






Respiratory Protection (Specify Type): NIOSH/MSHA approved dust, mist, vapor cartridge respirator.

Ventilation: Local Exhaust: To maintain conc. at low exposure levels.             Mechanical (General): Not recommended

Special: Handle in a controlled atmosphere.                                                          Other: Handle in an inert atmosphere such as argon.


Protective Gloves: Neoprene                                                                                 Eye Protection: Safety glasses

Other Protective Clothing or Equipment: Protective gear not necessary for magnesium nitride.


Work/Hygienic/Maintenance 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.
