SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating. This produces phosgene. Decomposes on contact with water. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163). Attacks many metals in the presence of water or moist air.
Chemical stability
no data available
Possibility of hazardous reactions
COMBUSTIBLEBENZYL CHLOROFORMATE decomposes slowly in water forming benzyl alcohol, HCl, and CO2. Gives off HCl fumes in moist air. Reacts with bases, both organic and inorganic. Attacks many metals especially in humid atmosphere [Handling Chemicals Safely 1980. p. 476]. Catalytic impurity incidents involving the iron catalyzed decomposition of benzoyl chloroformate have caused several explosions. The iron presumably comes from corrosion of steel storage tanks [Loss Prev. Bull., 1975, (003), 2]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
Conditions to avoid
no data available
Incompatible materials
Forms hydrogen chloride (hydrochloric acid) with water; reaction is very vigorous in cold water
Hazardous decomposition products
Emits highly toxic phosgene fumes when heated to 100 deg c.

SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

Other Information
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 is therefore essential.Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
