V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of barium aluminide have not been thoroughly investigated and recorded.
Barium compounds: The soluble barium salts, such as the chloride and sulfide, are poisonous when ingested. The salts mentioned are somewhat caustic.
Aluminum compounds have many commercial uses and are commonly found in industry. Many of these materials are active chemically and thus exhibit dangerous toxic and reactive properties. Inhalation of fine aluminum oxide particles is associated with Shaver’s disease. (Sax, Dangerous Properties of Industrial Materials)
Acute Effects:
Inhalation: May cause irritation to the respiratory system, dizziness, nausea, vomiting, colic, diarrhea, rapid respiration, high blood pressure, irregular heart action, convulsions, paralysis and acute barium poisoning..
Ingestion: May cause vomiting, colic, diarrhea, slow irregular pulse, transient hypertension, convulsions, tremors, muscular paralysis and acute barium poisoning.
Skin: May cause irritation.
Eye: May cause irritation.
Chronic Effects:
Inhalation: May cause pulmonary fibrosis and chronic barium poisoning.
Ingestion: May cause chronic barium poisoning and be implicated in Alzheimer’s disease.
Skin: May cause dermatitis.
Eye: May cause corneal opacity and blindness.
Routes of Entry: Inhalation, ingestion, skin, eyes.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders.
Target Organs: May affect the upper respiratory system, central nervous system, heart, skin and eyes.
Carcinogenicity: NTP: No IARC: No OSHA: No
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: Give 1-2 glasses of milk or water, induce vomiting, seek medical attrention. Never induce vomiting or give anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing, brush material off of skin, wash affected area with mild soap and water. Seek medical attention if symptoms persist.
EYES: Flush with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist.
VI REACTIVITY DATA

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. 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: In accordance with Local, State and Federal Waste Disposal Regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH-approved dust-mist-vapor respirator.
Ventilation: Use local exhaust to maintain concentration at or below PEL, TLV. General exhaust is recommended.
Protective Gloves: Rubber gloves.
Eye Protection: Safety goggles
Other Protective Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in a tightly sealed container in a cool, dry, well-ventilated area. 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 and 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.
