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.
V HEALTH HAZARD INFORMATION
Routes of Entry: Inhalation, skin, eyes, and ingestion.
Health Hazards (acute
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
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
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
OSHA Regulated? No
LD/LC50: No toxicity data recorded.
Signs and Symptoms of
Inhalation: May cause coughing, sneezing, difficulty breathing, swelling of the mouth and
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.
EMERGENCY AND FIRST AID
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.
VI. REACTIVITY DATA
to Avoid): Water, moisture, strong acids and bases.
Hazardous Polymerization: Will not Occur
Products: Magnesium oxide and ammonia.
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- 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
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.
VIII. SPECIAL PROTECTION
(Specify Type): NIOSH/MSHA approved dust, mist, vapor cartridge
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
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.
IX. SPECIAL PRECAUTIONS
Some of the chemicals listed
herein are research or experimental substances which may be toxic, as defined by various governmental regulations. In accordance
with Environmental Protection Agency regulations and the Toxic Substance Control Act (TSCA), these materials should only be
handled by, or under the direct supervision of a technically qualified individual, as defined in 40 CFR 710.2(aa).
The above information is
accurate to the best of our knowledge. However, since, data, safety standards, and government regulations are subject to change,
and the conditions of handling and use or misuse are beyond our control, ESPI makes no warranty, either expressed or implied,
with respect to the completeness or continuing accuracy of the information contained herein, and dis-claims all liability
for reliance thereon. Users should satisfy themselves that they have all current data relevant to their particular use.
