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. Cover powder
spill with plastic sheet or tarp to minimize spreading. Contact radiation
safety officer.
Stability No data.
Fire.
Fire fighting 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.
Health.
Exposure effects
Ingestion 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.
Skin See Inhalation.
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 Apply artificial respiration if victim 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.
