Additional information: The lists that were 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.

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.

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.

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.

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, and the chemical mixture.
  • Selection of the glove material on consideration of the penetration times, rates of diffusion, and the degradation
  • Material of gloves: 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.
