- 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 powder spill with plastic sheet or tarp to minimize spreading.
- Contact radiation safety officer.
Stability: Stable under recommended storage conditions.
4. EXPOSURE CONTROLS AND PERSONAL PROTECTION
Components with limit values that require monitoring at the workplace: Not required.
Additional information: The lists that were valid during the creation were used as basis.
- 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.
- In case of brief exposure or low pollution, use respiratory filter device.
- In case of intensive or longer exposure, use 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 to 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
Material of gloves: The selection of the suitable gloves does not only depend on the material, but also on further marks of quality and varies from manufacturer to manufacturer.
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.
Presence of radioactive material will not influence the fire control processes and should not influence selection of techniques.
- 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.
Ingestion, skin, and eyes: See inhalation.
- Minimal risk if packaging remains intact.
- Package damage can result in a measurable release of radiation, but the risk is still low.
First Aid Measures
- Consult a physician.
- Show this safety data sheet to the doctor in attendance.
- Move out of dangerous area.
- Apply artificial respiration if 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.
- Medical problems take priority over radiological concerns.
- Use first aid treatment according to the nature of the injury.
- Do not delay care and transport of a seriously injured person.
