Air & Water Reactions
Soluble in water.
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
Inorganic oxidizing agents can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). The chemical reduction of materials in this group can be rapid or even explosive, but often requires initiation (heat, spark, catalyst, addition of a solvent). Inorganic oxidizing agents can react violently with active metals, cyanides, esters, and thiocyanates. Explosives often consist of an inorganic oxidizing agent mixed in intimate contact with a reducing agent. Gunpowder is such a mixture. Other examples are a mixture of sugar (an organic compound) plus sodium chlorate and magnesium (an inorganic reducing agent) plus barium peroxide. Compounds that inherently contain a group that is a reducing agent and an oxidizing agent are classed in both Group 44 (Inorganic Oxidizing Agents) and in Group 45 (Inorganic Reducing Agents; for example, ammonium nitrate). The strongly oxidizing elements oxygen and fluorine are classified here. Inorganic oxidizing agents that are also acids (such as nitric and perchloric acids) are not included in this group. They are in Group 2 (Acids, Inorganic Oxidizing).

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)

Physical Properties

Physical Property fields

boiling point, as well as explosive limits and
toxic exposure thresholds
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.
