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 and cylinders from physical damage.
  • 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: 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. EXPOSURE CONTROLS AND PERSONAL PROTECTION

Control Parameters

Components with limit values that require monitoring at the workplace: Not required.

Additional information: The lists valid during the creation were used as a basis.

Exposure Controls

  • Keep away from foodstuffs, beverages, and feed.
  • Immediately remove all soiled and contaminated clothing.
  • Wash hands before breaks and at the end of work.
  • Store protective clothing separately.

Breathing equipment:

  • In case of brief exposure or low pollution, use a respiratory filter device.
  • In case of intensive or longer exposure, use a respiratory protective device that is independent of circulating air.

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.

Protection of hands:

  • The glove material must be impermeable and resistant to the product/ the substance and the preparation.
  • Due to missing tests, no recommendation for the glove material can be given for the product/ the preparation/ the chemical mixture.
  • Selection of the glove material on consideration of the penetration times, rates of diffusion, and the degradation

The selection of appropriate gloves depends on the material, while the quality standards may vary among manufacturers.

Penetration time of glove material: The exact break-through time must be found out by the manufacturer of the protective gloves and must be observed.

Eye protection: Not required.

Clothing: 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.

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.

5. 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.

6. 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 Measures

General advice:

  • Consult a physician.
  • Show this safety data sheet to the doctor in attendance.
  • Move out of dangerous areas.

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.

7. ACCIDENTAL RELEASE MEASURES

Personal precautions, protective equipment, and emergency procedures:

  • Wear respiratory protection.
  • Avoid dust formation, breathing vapors, breathing dust, mist, or gas.
  • Ensure adequate ventilation.
  • Evacuate personnel to safe areas.
  • For personal protection see section 8.

Environmental precautions:

  • Prevent further leakage or spillage if safe.
  • Do not let the product enter drains.

Methods and materials for containment and cleaning up:

  • Pick up and arrange disposal without creating dust.
  • Sweep up and shovel.
  • Keep in suitable, closed containers for disposal.

8. WASTE TREATMENT METHODS

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.

Uncleaned packaging:

  • Disposal must be made according to official regulations.
  • Recommended cleansing agent: Water, if necessary, with cleansing agents.
