Inhalation:

  • Toxic by inhalation.
  • Irritating to the nose, mucous membranes, and respiratory tract.

Ingestion: Toxic if swallowed.

Acute health effects

  • Toxic by inhalation and if swallowed.
  • Irritating to skin, eyes, and respiratory tract.

Chronic health effects

4. FIRST AID MEASURES

Eye exposure:

  • Immediately flush the eyes with copious amounts of water for at least 20 minutes.
  • A victim may need assistance in keeping their eye lids open.
  • Get immediate medical attention.
  • See ingestion.

Skin exposure:

  • Wash the affected area with water.
  • Immediately flush with running water for at least 20 minutes.
  • Remove contaminated clothes if necessary.
  • Seek medical assistance if irritation persists.
  • See Ingestion.

Inhalation:

  • Remove the victim to fresh air.
  • Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain.
  • Apply artificial respiration if victim is not breathing.
  • Administer oxygen if breathing is difficult.
  • Seek immediate medical assistance.
  • See Ingestion.

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.
  • Give the victim water (only if conscious).
  • Induce vomiting (only if directed by medical personnel).

5. 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 protection: May burn, but it does not ignite rapidly.

  • Flash point: Not applicable.
  • Autoignition temperature: None.
  • Explosion limits: None.
  • Extinguishing medium: Not applicable.
  • Special firefighting procedures: None.
  • Hazardous combustion and decomposition products: None.
  • Unusual fire or explosion hazards: None.

6. HANDLING AND STORAGE

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: If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to follow 29 CFR 1910.134. Wear positive pressure self-contained breathing apparatus (SCBA).

Ventilation: Material may form a fine dust. If possible, handle the material in an efficient fume hood.

Small spills and leaks:

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

  • 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.
