SECTION 5: Firefighting measures
Suitable extinguishing media
Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]: When material is not involved in fire, do not use water on material itself. SMALL FIRE: Dry chemical or CO2. Move containers from fire area if you can do it without risk. LARGE FIRE: Flood fire area with large quantities of water, while knocking down vapors with water fog. If insufficient water supply: knock down vapors only. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Cool containers with flooding quantities of water until well after fire is out. Do not get water inside containers. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)
Specific hazards arising from the chemical
Behavior in Fire: Vapors are very irritating to eyes and mucous membranes. May increase severity of fire. (USCG, 1999)
Special protective actions for fire-fighters
Use carbon dioxide, special powder. NO hydrous agents. In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

SECTION 10: Stability and reactivity
Reactivity
Decomposes violently on contact with water. This produces toxic and corrosive fumes of hydrogen chloride, chlorine, chromium trioxide and chromium trichloride. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. Reacts violently with water, non-metal halides, non-metal hydrides, ammonia and certain common solvents such as alcohol, ether, acetone and turpentine. This generates fire and explosion hazard. Attacks many metals in the presence of water. Incompatible with plastics. Can ignite combustible substances.
Chemical stability
no data available
Possibility of hazardous reactions
CHROMIUM OXYCHLORIDE is a powerful and often violent oxidizing agent. Reacts readily with many inorganic and organic materials in the absence of a dilutent. Contact with hydrogen sulfide or phosphine can cause ignition. Contact with phosphorus tribromide, acetone, ethanol, ether, and turpentine causes ignition. Contact with moist phosphorus or with phosphorus trichloride leads to explosive reaction. Contact with ammonia causes incandescence. Reacts with sodium azide to form chromyl azide, which is explosive in the absence of a dilutent. Causes ignition of flowers of sulfur and of urea on contact. [Bretherick, 1979, p. 822-823].

AIR AND WATER REACTIONS: Fumes in moist air. Hydrolyses vigorously in contact with water, Merck, 11th ed., 1989.CHEMICAL PROFILE: Powerful and often violent oxidant of inorganic and organic materials in the absence of a diluent; contact with ammonia causes incandescence; hydrogen sulfide and phosphine may ignite upon contact; acetone, ethanol, ether, and turpentine ignite on contact; moist phosphorus or phosphorus trichloride explodes, phosphorus tribromide ignites, is explosive in contact with the liquid chloride; interaction with sodium azide to form chromyl azide is explosive in the absence of a diluent; contact with flowers of sulfur causes ignition; urea ignites in contact with the chloride(Bretherick, 1979, p. 822-823).

Other Information
Dissolves chromium trioxide, yielding a powerful oxidant.Reacts violently with fire extinguishing agents such as water.Depending on the degree of exposure, periodic medical examination is indicated.The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation are therefore essential.Do NOT take working clothes home.Rinse contaminated clothing with plenty of water because of fire hazard.
