IV.  FIRE AND EXPLOSION HAZARDS DATA

Flash Point:  N/A

Flammability:  Highly flammable

Autoignition Temperature:  N/E

Explosive LimitsLower:  N/E Upper: N/E

Extinguishing Media:  FLAMMABLE SOLID!!  Use dry chemical/dolomite (powdered limestone) or sodium chloride.  DO NOT USE WATER, CARBON DIOXIDE, OR HALOGENATED EXTINGUISHERS!

Special Firefighting Procedures:  Wear full face, self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.  Flammable solid.

Unusual Fire and Explosion Hazards:  Material readily reacts with water generating flammable and/or explosive hydrogen gas.  Emits toxic fumes under fire conditions.  Caution! Fire may reignite after having been extinguished.  Blend with large excess of dolomite.

 

 

V.  HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical, and toxicological properties of barium 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.

Acute Effects:

Inhalation:  May cause severe irritation to the nose, throat, and upper respiratory tract.

Ingestion:  May cause severe irritation of the mouth, throat, and esophagus.

Skin:  Contact with skin can cause mild to moderate irritation.  May cause chemical burns as it reacts with moisture on living tissue.  Can lead to the development of a hypersensitivity in susceptible individuals.

EyeMay cause chemical burns as it reacts with moisture on living tissue.

Chronic Effects:

Inhalation:  May cause sensitization.

Ingestion:  May cause chronic barium poisoning.

Skin:  May cause dermatitis.

Eye:  May cause corneal opacity and blindness.

Target Organs:  Respiratory System, Eye, Skin, Immune System (Allergic Reactions), Central Nervous System, and Heart.

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

CarcinogenicityNTP:  No        IARC:  No        OSHA:  No

 

EMERGENCY AND FIRST AID PROCEDURES:

INHALATIONRemove to fresh air, keep warm and quiet, give oxygen if breathing is difficult, seek  immediate medical attention.

INGESTION:  Seek immediate medical attention.

SKINRemove metal particles.  Remove contaminated clothing. Carefully brush material off skin and wash area with soap and water.  Seek medical attention if irritation develops.

EYERemove metal particles.  Contamination of the eyes should be treated by immediate and prolonged irrigation with copious amounts of water.  Lift upper and lower eye lids frequently.  Get prompt medical attention.

NOTE TO PHYSICIAN:  Treatment should be directed at preventing absorption, administering to the symptoms as they occur, and providing supportive therapy.  Attention: Up to two days latent period.

 

 

VI.  REACTIVITY DATA

Stability:  Stable if used and stored according to specifications.

Conditions to Avoid:  Water or moisture and air.  Avoid friction, heat, sparks, and flame.

Incompatibility (Materials to Avoid):  Water or moisture, oxidizing agents, oxygen, acids, alcohols, halocarbons, carbon dioxide, ammonia.

Hazardous Decomposition Products:  Toxic fumes of hydrogen and barium oxide.

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 specified in section VIII.  Isolate spill area and provide ventilation.  Protect from ignition sources.  Keep unprotected persons away.  Sweep or scoop spilled product and place in a closed container for further handling and disposal.  Do not flush to sewer, stream, or other bodies of water.  Cover very small quantities in the open with powdered limestone and let decompose.

Waste Disposal Method:  Material in the elemental state should be recovered for reuse or recycling.  Observe all federal, state & local regulations.

 

 

VIII.  SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH approved cartridge respirator.

VentilationUse process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below exposure limits.  Handle in a controlled environment in an inert gas.

Protective Gloves:  Leather-palmed, heat resistant gloves.

Eye Protection:  Chemical splash goggles and a full face shield.  An eye wash facility should be readily available.

Other Protective Clothing or Equipment:  The use of fire resistant outer clothing is advisable.

 

 

IX.  SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Barium metal should be stored in tightly-closed containers under argon or mineral oil.  When handling, wear non-sparking shoes and flame resistant clothing.  Avoid friction, heat, sparks, and flame.  Use only non-sparking tools and utensils.  Ground all equipment, vessels, tables, and other metallic objects that may come into contact with the product.  Do not store together with acids, halogens and oxidizing agents.  Store away from water/moisture.

Other Precautions:   Can autoignite in air. Extremely sensitive to shock, heat, friction and static electricity.  Rubber gloves, rubber protective clothing and apron, goggles and gas filter mask should be worn when working in a barium storage area.

Empty Container Precautions:  This container is hazardous when empty.  Do not use heat, sparks, open flame, torches, or cigarettes on or near empty container.  Empty containers can retain product residues.  Do not reuse empty container for food, clothing, or other products for human or animal consumption or where skin contact may occur.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels.  Do not use tobacco or food in work area.  Wash thoroughly after handling, especially before eating, drinking, smoking, or using restroom facilities. Contaminated clothing and shoes should be thoroughly cleaned before reuse.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
