V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of lanthanum nitride have not been thoroughly investigated and recorded.
Lanthanum is considered a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of the rare earth elements include writhing, ataxia, labored respiration, walking on the toes with arched back and sedation. The rare earth elements exhibit low toxicity by ingestion exposure. However, the intraperitoneal route is highly toxic while the subcutaneous route is poison to moderately toxic. The production of skin and lung granulomas after exposure to them requires extensive protection to prevent such exposure.
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 to the upper respiratory system. Ammonia gas may cause irritation to the nose and throat, dyspnea, bronchial spasms, chest pain, pulmonary edema and pink frothy sputum.
Ingestion: May cause irritation by ingestion. Ammonia gas may cause nausea, vomiting and burns.
Skin: May cause irritation. Ammonia gas may cause nausea, vomiting and burns.
Eye: May cause moderate irritation. Ammonia gas may cause severe irritation and chemical burns.
Chronic Effects:
Inhalation: May cause writhing, ataxia, labored respiration, walking on toes with arched back, sedation, pulmonary edema and lung granuloma. Repeated or prolonged exposure to ammonia gas may cause swelling of mouth and throat to the point of asphyxiation, permanent injury and death.
Ingestion: May act as a blood anticoagulant.
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.
Carcinogenicity: NTP: No IARC: No OSHA: No
Target Organs: May affect the respiratory system, blood, skin and eyes.
Medical Conditions Generally Aggravated by Exposure: Pre-existing lung and skin disorders.
EMERGENCY AND FIRST AID PROCEDURES:
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 contaminated clothing, brush material off skin, wash affected area with mild soap and water, seek medical attention.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.
VI REACTIVITY DATA
Stability: Stable
Conditions to Avoid: None
Incompatibility (Material to avoid): None recorded
Hazardous Decomposition Products: Ammonia and hydrogen gas.
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 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: Disposal must be made in accordance with Federal, State and Local regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): Use a NIOSH/MSHA approved dust respirator.
Ventilation: Use local exhaust to maintain concentration at or below the PEL, TLV. Mechanical exhaust is recommended.
Protective Gloves: Rubber gloves
Eye Protection: Safety glasses or goggles
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in a cool, dry place in tightly closed containers. Avoid breathing dusts. Avoid direct or prolonged contact with skin and eyes. Wash hands thoroughly after handling. Do not rub eyes with soiled hands. Do not eat, drink or smoke in the work area.
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 the work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.
The above information is believed to be correct, but does not purport to be all inclusive and shall be used only as a guide. ESPI shall not be held liable for any damage resulting from handling or from contact with the above product.
