General Description
Yellow crystals with a slight odor of vinegar. Density 2.89 g / cm3.

The Hazard fields include special hazard alerts, air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.
Reactivity Alerts
  • Radioactive Material
Air & Water Reactions
Water soluble, reacting to give a milky solution. The reaction is not hazardous.
Fire Hazard
Excerpt from ERG Guide 161 [Radioactive Materials (Low Level Radiation)]:

Some of these materials may burn, but most do not ignite readily. Many have cardboard outer packaging; content (physically large or small) can be of many different physical forms. Radioactivity does not change flammability or other properties of materials. (ERG, 2016)
Health Hazard
Inhalation of dust may irritate nose and throat. Contact with eyes causes irritation. (USCG, 1999)
Reactivity Profile
URANYL ACETATE reacts weakly as an acid. Usually does not react as either oxidizing agents or reducing agents but such behavior is not impossible. May catalyze organic reactions.
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

No information available.

The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources.
Isolation and Evacuation
Excerpt from ERG Guide 161 [Radioactive Materials (Low Level Radiation)]:

As an immediate precautionary measure, isolate spill or leak area for at least 25 meters (75 feet) in all directions.

LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet).

FIRE: When a large quantity of this material is involved in a major fire, consider an initial evacuation distance of 300 meters (1000 feet) in all directions. (ERG, 2016)
Firefighting
Excerpt from ERG Guide 161 [Radioactive Materials (Low Level Radiation)]:

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 FIRE: Dry chemical, CO2, water spray or regular foam.

LARGE FIRE: Water spray, fog (flooding amounts). (ERG, 2016)
Non-Fire Response
Excerpt from ERG Guide 161 [Radioactive Materials (Low Level Radiation)]:

Do not touch damaged packages or spilled material. Cover liquid spill with sand, earth or other non-combustible absorbent material. Cover powder spill with plastic sheet or tarp to minimize spreading. (ERG, 2016)
Protective Clothing
Approved dust respirator; goggles or face shield; protective clothing (USCG, 1999)
DuPont Tychem® Suit Fabrics

First Aid
Get medical attention after all exposures to this compound.

INHALATION: move to fresh air.

INGESTION: give large amount of water; induce vomiting.

EYES: flush with water for at least 15 min.

SKIN: flush with water. (USCG, 1999)
