General Description
A purple-colored crystalline solid. Less dense than water. May ignite organic materials upon contact. Contact may irritate skin, eyes, and mucous membranes. Toxic by ingestion. Used to make other chemicals.
Hazards
Reactivity Alerts
Air & Water Reactions
Soluble in water.
Fire Hazard
Excerpt from 141
[Oxidizers - Toxic]:
These substances will accelerate burning when involved in a fire. 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. (ERG, 2020)
Health Hazard
Excerpt from 141
[Oxidizers - Toxic]:
Toxic by ingestion. Inhalation of dust is toxic. Fire may produce irritating, corrosive and/or toxic gases. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause environmental contamination. (ERG, 2020)
Reactivity Profile
Self-reactive. Chromium nitrates may be shock sensitive. Mixtures of metal/nonmetal nitrates with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures of nitrate with phosphorus, tin (II) chloride or other reducing agents may react explosively [Bretherick, 1979 p. 108-109].

Response Recommendations
Isolation and Evacuation
Excerpt from 141
[Oxidizers - Toxic]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet).
FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)
Firefighting
Excerpt from 141
[Oxidizers - Toxic]:
SMALL FIRE: Use water. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control.
LARGE FIRE: Flood fire area with water from a distance. Do not move cargo or vehicle if cargo has been exposed to heat. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2020)
Non-Fire Response
Excerpt from 141
[Oxidizers - Toxic]:
Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk.
SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.
LARGE SPILL: Dike far ahead of spill for later disposal. (ERG, 2020)
Protective Clothing
Excerpt from ERG Guide 141 [Oxidizers - Toxic]:
Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE. Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. (ERG, 2020)

First Aid
Excerpt from 141
[Oxidizers - Toxic]:
Call 911 or emergency medical service. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air if it can be done safely. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. Contaminated clothing may be a fire risk when dry. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Keep victim calm and warm. (ERG, 2020)
