3. HAZARDS AND PROTECTION

Storage:

• Keep in a cool, dry, dark location, in a tightly sealed container or cylinder.
• Keep away from incompatible materials, ignition sources, and untrained individuals.
• Secure and label area.
• Protect containers/cylinders from physical damage.

Handling:

• All chemicals should be considered hazardous.
• Avoid direct physical contact.
• Use appropriate approved safety equipment.
• Untrained individuals should not handle this chemical or its container.
• Handling should occur in a chemical fume hood.

Protection: Wear appropriate protective gloves, clothing, and goggles.

Respirators: Wear positive pressure self-contained breathing apparatus (SCBA).

Small spills and leaks:

• Do not touch damaged packages or spilled material.
• Cover liquid spill with sand, earth, or other noncombustible absorbent material.
• Cover the powder spill with a plastic sheet or tarp to minimize spreading.
• Contact the radiation safety officer.

Stability: Stable under recommended storage conditions.

4. FIREFIGHTING

The presence of radioactive material will not affect the fire control procedures and technique selection.

• Small fires: Dry chemical, carbon dioxide, water spray, or regular foam.
• Large fires: Water spray, fog (flooding amounts).

Fire potential: May burn but does not ignite readily.

5. HEALTH

Exposure Effects

Ingestion, skin, and eyes: See inhalation.

Inhalation:

• There is minimal risk if the packaging remains intact.
• Package damage can result in a measurable release of radiation, but the risk is still low.

First Aid

General advice: In the case of an accident or if you feel unwell, seek medical advice immediately.

Inhalation:

• Apply artificial respiration if the patient is not breathing.
• Administer oxygen if breathing is difficult.
• See Ingestion.

Skin and eyes:

• Immediately flush with running water for at least 20 minutes.
• See Ingestion.

Ingestion:

• Medical problems take priority over radiological concerns.
• Use first aid treatment according to the nature of the injury.
• Do not delay the care and transport of a seriously injured person.

6. EXPOSURE CONTROLS AND GENERAL PROTECTION

Engineering measures: Ensure adequate ventilation.

Personal Protective Equipment

Respiratory protection: Breathing apparatus only if aerosol or dust is formed.

At any detectable concentration: Any self-contained breathing apparatus with a full facepiece operated in a pressure-demand or other positive-pressure mode.

Any supplied-air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode or other positive-pressure mode with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode.

Escape – any air-purifying, full-facepiece respirator with a high-efficiency particulate filler.

Any appropriate escape-type, self-contained breathing apparatus.

Hand protection: PVC or other plastic material gloves. The selection of appropriate gloves depends on the material, while the quality standards may vary among manufacturers.

Skin and body protection: Usual safety precautions while handling the product will provide adequate protection against this potential effect.

Employees handling radioactive substances should wear disposable overgarments, including head and foot coverings. These garments are also recommended even if the employee uses a “glove box” containment system. Certain clothing fibers may be useful in dosimetry so clothing should be kept.

Eye protection: Safety glasses with side-shields

Hygiene measures: Handle following good industrial hygiene and safety practices.

Firefighting and Other Immediately Dangerous to Life or Health Conditions

Use any self-contained breathing apparatus with a full facepiece respirator and a high-efficiency particulate filter.

Use any supplied-air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode or other positive-pressure modes with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure modes.

7. DISPOSAL CONSIDERATIONS

Waste from residues/unused products: Waste disposal must follow appropriate Federal, State, and local regulations. If unaltered, this product may be disposed of by treatment at a permitted facility or as advised by your local hazardous waste regulatory authority. Residue from fires extinguished with this material may be dangerous.

Contaminated packaging: Do not reuse empty containers and dispose of them as unused products.

Recommendations: Should not be disposed of with household garbage.

8. TRANSPORTATION
