3. HAZARDS AND PROTECTION

Uranyl Hydroxide Is precipitated as a colloidal yellowcake from oxidized uranium liquors near neutral pH.

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.

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 powder spill with a plastic sheet or tarp to minimize spreading.
• Contact the radiation safety officer.

4. FIREFIGHTING

The presence of radioactive material will not influence the fire control processes and should not influence the 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.

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.

Exposure Controls

General protective and hygienic measures:

• 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.
• Avoid contact with the eyes.
• Avoid contact with the eyes and skin.

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 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:

• Protective gloves:  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 suitable gloves depends on the material and 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: Tightly sealed goggles

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.

First Aid

General information:

• Immediately remove any clothing soiled by the product.
• Symptoms of poisoning may even occur after several hours.
• Therefore, medical observation for 48 hours after the accident.
• Remove the breathing apparatus only after contaminated clothing has been completely removed.
• In case of irregular breathing or respiratory arrest provide artificial respiration

Skin and eyes:

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

Inhalation:

• Apply artificial respiration if the patient is not breathing.
• Administer oxygen if breathing is difficult.
• 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. WASTE TREATMENT METHODS

Recommendation:

• Must not be disposed of together with household garbage.
• Do not allow the product to reach the sewage system.

Uncleaned Packaging:

Recommendation: Disposal must be made according to official regulations.

Recommended cleansing agent: Water, if necessary, with cleansing agents.
