IV         FIRE AND EXPLOSION HAZARDS DATA


 

 

Flash Point: N/A                                                                                                    Autoignition Temperature:

Explosive Limits: Lower: N/E    Upper: N/E

 

Extinguishing Media: Use suitable extinguishing media for surrounding material and type of fire.

Special Fire Fighting Procedures: Wear full face, and 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 and Explosion Hazards: Barium boride may emit toxic fumes of boron and barium oxide if involved in a fire.

 

 

V           HEALTH HAZARD DATA


 

 

Effects of Exposure:

 

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

 

              Barium compounds may cause severe gastroenteritis, including abdominal pain, vomiting and diarrhea, tremors, faintness, paralysis of the arms and legs, and slow or irregular heartbeat. Severe cases may produce collapse and death due to respiratory failure. Soluble barium compounds are more likely to cause these effects than insoluble compounds. Inhalation of fumes may cause sore throat, coughing, labored breathing, and irritation of the respiratory tract as well as the above symptoms.

 

 

              Boron compounds are very toxic and therefore considered an industrial poison. Boron is one of a group of elements, such as Pb, Mn, As, which effects the central nervous system. Boron poisoning causes depression of the circulation, persistent vomiting and diarrhea, followed by profound shock and comma. The temperature becomes subnormal and a scarlatina form rash may cover the entire body (Sax, Dangerous Properties of Industrial Materials).

 

Acute Effects:

 

Inhalation: May cause respiratory irritation, dizziness, nausea, vomiting, colic, diarrhea, rapid respiration, high blood pressure, irregular heart action, convulsions, paralysis and acute barium poisoning.

Ingestion: May cause poisoning, vomiting, colic, diarrhea, slow irregular pulse, transient hypertension convulsions, tremors, muscular paralysis, and acute barium poisoning.

Skin: May cause irritation.

Eye: May cause irritation and inflammation.

 

Chronic Effects:

 

Inhalation: May cause pulmonary granulomas and chronic barium poisoning.

Ingestion: May cause chronic barium poisoning.

Skin: May cause dermatitis.

Eye: May cause corneal opacity and blindness.

 

Target Organs: May affect the respiratory and central nervous system, heart, skin and eyes.

 

Carcinogenicity: NTP: No           IARC Monographs: No                OSHA Regulated: No

 

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

 

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: If conscious, give 1-2 glasses of milk or water and induce vomiting, seek medical attention. Never give anything by mouth or induce vomiting on an unconscious person.

SKIN: Remove contaminated clothing from affected area, brush material off skin, wash affected area with mild soap and water, seek medical attention if symptoms persist.

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

 

 

VI         REACTIVITY DATA


 

 

Stability: Stable

 

Conditions to Avoid: None

Incompatibilities: Strong acids and bases.

VII        PRECAUTIONS FOR SAFE HANDLING AND USE


 

 

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: Observe all federal, state & local regulations.

 

 

VIII      SPECIAL PROTECTION INFORMATION


 

 

Respiratory Protection (Specify Type): Wear a NIOSH-approved dust respirator.

Ventilation: Use local exhaust to maintain concentration at or below the PEL, TLV. General exhaust is recommended.

 

Protective Gloves: Rubber gloves.

Eye Protection: Safety glasses

 

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

 

 

IX         SPECIAL PRECAUTIONS


 

 

Precautions to Be Taken in Handling and Storage: Store in cool, dry area. Store in tightly sealed container. Wash thoroughly after handling.

 

Other Precautions: Do not store together with acids. Store away from oxidizing agents.

 

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.

 

              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.
