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, 2024)

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

Response Recommendations

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)]:
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, 2024)

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. If it can be done safely, move undamaged containers away from the area around the fire. 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, 2024)

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, 2024)

The information in CAMEO Chemicals comes from a variety of
data sources.
Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
