Hazards and Protection.
Storage
Protect from physical damage. Store at in cool, dry place. Protect personnel from radiation emanation if present. Separate from other readily oxidizable or combustible materials.
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
Approved dust respirator self contained breathing apparatus; goggles or face shield; protective clothing.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Stability
No data.
Incompatibilities
Can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers) Can react violently with active metals, cyanides, esters, and thiocyanates.

Fire.
Fire fighting
Use appropriate media to suppress exposure fire. Contain runoff.

Health.
Exposure limit(s)
OSHA: PEL (8 h TWA): 0.05 mg
Exposure effects
Supralethal radiation doses may result in headache, acute brain syndrome, alterations in mental status including coma, and (rarely) seizures within minutes of exposure. Prenatal ionizing radiation exposure may cause congenital anomalies, mental retardation, and an increased incidence of seizures.
   Ingestion
Gastrointestinal syndrome (nausea/vomiting) commonly occurs after doses of 9 to 20 gy and may occur following doses as low as 5 gy. Initial vomiting is followed by persistent diarrhea, which may be bloody.
   Inhalation
Pulmonary radiation injury may result in radiation pneumonitis and radiation pulmonary fibrosis.
   Skin
Thermonuclear burns may occur. If erythema is produced by a penetrating radiation, serious systemic injury is certain.

First aid
 
   Ingestion
Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
   Inhalation
Monitoring exposed patients for contamination and decontamination procedures should be started. All personnel involved in handling patients should wear disposable protective clothing. The patient should be completely undressed and given a soap and water bath or shower (if the patient's condition permits and if the facility exists). Acute inhalation of radionuclides presents some difficult problems.
   Skin
Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse.
   Eyes
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.
