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/leaks Do not touch damaged packages or spilled material. Cover
liquid spill with sand, earth or other noncombustible absorbent material.
Dike to collect large liquid spills. Cover powder spill with plastic sheet
or tarp to minimize spreading.
Stability No data.
Incompatibilities  
Fire.
Fire fighting Presence of radioactive material will not
influence the fire control processes and should not influence selection of
techniques. Move containers from fire area if you can do it without risk. Do
not move damaged packages; move undamaged packages out of fire zone.

SMALL FIRES: Dry chemical, carbon dioxide, water spray or regular foam.

LARGE FIRES: Water spray, fog (flooding amounts). Dike fire-control water for
later disposal.

Fire potential Material itself does not burn or burns with
difficulty.
Hazards Some of these materials may burn, but most do
not ignite readily. Uranium and Thorium metal cuttings may ignite
spontaneously if exposed to air. Extremely flammable; will ignite itself if
exposed to air. Burns rapidly, releasing dense, white, irritating fumes.
Substance may be transported in a molten form. May re-ignite after fire is
extinguished. Nitrates are oxidizers and may ignite other combustibles. May
explode from heat or contamination. Some may burn rapidly. Some will react
explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper,
oil, clothing, etc.). Containers may explode when heated. Runoff may create
fire or explosion hazard.
Health.
Exposure limit(s) OSHA PEL: 0.05 mg/m3
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.
   Eyes See Inhalation.
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 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 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.
