4. 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 at recommended storage conditions.

5. FIRE

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.

6. HEALTH

Health Exposure Effects

• Ingestion, skin & eyes: See Inhalation

• Inhalation: Minimal risk if packaging remains intact. Package damage can result in a measurable release of radiation, but the risk is also still low.

First Aid

• 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.

• 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.
