With interhalogens

There have not been any accidents recorded that have mentioned metal halides (except with interhalogens , which are very reactive anyway). Nevertheless, it seems important that calcium should not be in contact with such halides without taking any precautions. It was noticed that calcium starts glowing when it is heated with boron trifluoride. 

Carbon monoxide is a highly flammable and poisonous gas. Its flammable limits in air are 12.5 to 74.2% by volume, and the autoignition temperature 700°C. It explodes when exposed to flame. Reactions with interhalogen compounds, such as, bromine pentafluoride or halogen oxides can cause explosion. It forms explosive products with sodium or potassium that are sensitive to heat and shock. 

SAFETY PROFILE A human poison by an unspecified route. Poison experimentally by inhalation. An eye, mucous membrane, and systemic irritant by inhalation. Mutation data reported. A common air contaminant. Difficult to ignite. Explosion hazard when exposed to flame or in a fire. NH3 + air in a fire can detonate. Potentially violent or explosive reactions on contact with interhalogens (e.g., bromine pentafluoride, chlorine trifluoride), 1,2-dichloroethane (with liquid NH3), boron halides, chloroformamideium nitrate, ethylene oxide (polymerization reaction), magnesium... 

SAFETY PROFILE Inhalation of the fumes can produce a febrile reaction and leucocytosis in humans. Questionable carcinogen with experimental tumorigenic data. Violent reaction or ignition in contact with interhalogens (e.g., bromine pentafluoride, chlorine trifluoride). Incandescent reaction with phosphorus pentachloride. See also MAGNESIUM COMPOUNDS. 

Flammable gas. Very dangerous fire hazard when exposed to heat, flame, or powerful oxidizers. Moderate explosion hazard when exposed to flame and sparks. Explodes on contact with interhalogens (e.g., bromine trifluoride, bromine pentafluoride), magnesium and alloys, potassium and alloys, sodium and alloys, zinc, Potentially explosive reaction with aluminum when heated to 152° in a sealed container. Mixtures with aluminum chloride + ethylene react exothermically and then explode when pressurized to above 30 bar. May ignite on contact with aluminum chloride or powdered aluminum. To fight fire, stop flow of gas and use CO2, dry chemical, or water spray. When heated to decomposition it emits highly toxic fumes of cr. See also CHLORINATED HYDROCARBONS, ALIPHATIC. 

Bimodal rotational energy distributions have been observed [267] for the HCl product from the reaction H + SQ2, indicative of the existence of both a direct and migratory mechanism as was observed in the reactions of H atoms with interhalogen molecules [see Sect. 3.1.1(c)]. The internal energy disposal was determined to be = 0.42 and >...
