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 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 plastic sheet or tarp to minimize spreading. Contact radiation safety officer.

4. FIREFIGHTING

Firefighting: 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.

5. HEALTH AND EXPOSURES 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 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 care and transport of a seriously injured person.
• Inhalation: Apply artificial respiration if patient is not breathing. Administer oxygen if breathing is difficult. See Ingestion.
• Skin: Immediately flush with running water for at least 20 minutes. See Ingestion.
• Eyes: Immediately flush with running water for at least 20 minutes. See Ingestion.
