Extinguishing Media:  Use class D or other metal extinguishing agent.  DO NOT USE WATER.

Special Firefighting 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 Hazard:  May react with moist air to liberate ammonia gas, which may be an explosion hazard when exposed to flame or involved in a fire.




Effects of Exposure:

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

The fumes evolved by burning calcium in air are composed of calcium oxide (quick lime) which is an irritant to the skin, eyes and mucous membranes.  Generally speaking, calcium compounds should be considered toxic only when they contain toxic components or calcium oxide or hydroxide.  Calcium compounds are common air contaminants (Sax, Dangerous Properties of Industrial Materials, eighth edition).

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, eighth edition).

Acute Effects:

Inhalation:  May cause irritation and possibly corrosive to the nose, throat and mucous membranes, chemical pneumonia, chemical bronchitis and pulmonary edema.  Ammonia gas may cause irritation to the nose and throat, dyspnea, bronchial spasms, chest pain, pulmonary edema and pink frothy sputum.

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

Skin:  May be an irritant and possibly corrosive.  Ammonia gas may cause severe irritation and chemical burns.

Eye:  May be an irritant and possibly corrosive.  Ammonia gas may cause severe irritation and chemical burns.

Chronic Effects:

Inhalation:  May cause pulmonary fibrosis.  Repeated or prolonged exposure to ammonia 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.

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

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

CarcinogenicityNTP:  No          IARC:  No           OSHA:  No



INHALATION:  Remove victim 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 any contaminated clothing; brush material off skin; wash affected area with mild soap and water, seek medical attention.

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




Stability:  Stable

Conditions to Avoid:  None

Incompatibility (Material to Avoid):  Water, steam, moisture.

Hazardous Decomposition Products:  Ammonia gas, oxides of calcium and nitrogen.

Hazardous Polymerization:  Will not occur




Steps to Be Taken in Case Material Is Released or Spilled:  Wear appropriate respiratory and protective equipment.  Isolate spill area, provide ventilation and extinguish sources of ignition.  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.  Use non-sparking tools.

Waste Disposal Method:  Dispose of in accordance with Federal, State and Local regulations.




Respiratory Protection:  NIOSH approved dust and vapor cartridge respirator.

Ventilation:  Handle in a controlled atmosphere under a dry, protective gas such as argon.  Use local exhaust to maintain concentration at low levels.

Protective Gloves:  Butyl or polycarbonate gloves.

Eye Protection:  Safety glasses or goggles.

Other Protective Clothing or Equipment:  Protective gear suitable to prevent contamination.




Precautions to Be Taken in Handling and Storage:  Store in a cool, dry area in a tightly sealed container.  Store in an inert atmosphere and wash thoroughly after handling.

Other Precautions:  Calcium nitride is moisture sensitive, handle and store under argon or other 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 facilities for washing.
