V HEALTH HAZARD INFORMATION
Health Hazards (Acute and Chronic):
To the best of our knowledge the chemical, physical and toxicological properties of calcium nitride have not been thoroughly investigated and recorded. The details of the toxicity of nitrides as a group are unknown.
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).
Inhalation: Acute: 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.
Chronic: 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: Acute: Ammonia gas may cause nausea, vomiting and burns.
Chronic: No chronic health effects recorded.
Skin: Acute: May be an irritant and possibly corrosive. Ammonia gas may cause severe irritation and chemical burns.
Chronic: Repeated or prolonged exposure to ammonia gas may cause tissue damage.
Eye: Acute: May be an irritant and possibly corrosive. Ammonia gas may cause severe irritation and chemical burns.
Chronic: Repeated or prolonged exposure to ammonia gas may cause irreversible damage to the conjunctiva, cornea and lens.
LD50/LC50: No toxicity data recorded.
Route(s) of Entry: Inhalation, Skin And Eyes.
Target Organs: May affect the respiratory system, lungs, skin and eyes.
Carcinogenicity: NTP? No IARC Monographs? No OSHA Regulated? No
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory and skin disorders.
EMERGENCY AND FIRST AID PROCEDURES:
EYES: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.
SKIN: Remove any contaminated clothing; brush material off skin; wash affected area with mild soap and water, seek medical attention.
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.
VI REACTIVITY DATA
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
VII SPILL OR LEAK PROCEDURES
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.
Hazard Label Information: 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.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: NIOSH approved dust and vapor cartridge respirator.
Ventilation: Local Exhaust: To maintain concentration at low levels. Special: Handle in a controlled atmosphere.
Protective Gloves: Butyl or polycarbonate gloves. Eye Protection: Safety glasses or goggles.
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.
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 nor 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 Nor Implied, with Respect to the Completeness or Continuing Accuracy of the Information Contained Herein, and Disclaims All Liability for Reliance Thereon.
