V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

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

Most inorganic phosphates, except phosphine, have low toxicity but in large doses they may cause serious disturbances, particularly in calcium metabolism.  Metaphosphates may be highly toxic, causing irritation and hemorrhages in the stomach as well as liver and kidney damage.  Common air contaminants.

The details of toxicity of nitrides as a group are unknown.  However, many nitrides react with moisture to evolve ammonia.  This gas is an irritant to eyes and mucous membranes of the respiratory tract.  Irritation of the skin may be experienced, especially if it is moist.  Corneal ulcers have been reported following splashing of ammonia water in the eye.  A common air contaminant. (Sax, Dangerous Properties of Industrial Materials)

Acute Effects:

Inhalation:  CORROSIVE.  May result in respiratory effects such as inflammation, edema, and chemical pneumonitis.  May cause coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.

Ingestion:  CORROSIVE.  Swallowing will lead to a strong corrosive effect on mouth and throat and to the danger of perforation of esophagus and stomach.

Skin:  CORROSIVE.  May cause skin burns or irritation depending on the severity of the exposure.

Eye:  CORROSIVE.  Eye contact may result in permanent damage and complete vision loss.

Chronic Effects:  No data

Carcinogenicity:  No information found

 

EMERGENCY AND FIRST AID PROCEDURES:

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

INGESTION:  Give victim fluids to dilute compound, do not induce vomiting.  Seek immediate medical attention.

SKIN:  Immediately wash with water and soap and rinse thoroughly.  Seek immediate medical advice.

EYE:  Flush eyes with plenty of water for at least 15 minutes.  Then consult a doctor.

Eye Protection:  Safety glasses, tightly sealed goggles, full face protection.

Other Protective Equipment:   Protective gear suitable to prevent contamination.

 

 

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Store under dry inert gas.  Store in a cool, dry area.  Store away from water/moisture.  Store in tightly sealed container.  Store away from flammables.  Wash thoroughly after handling.

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 or 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.
