1,3-Dichloraceton

The major hazards encountered in the use and handling of bischloromethyl ketone stem from its toxicologic properties. Toxic by all routes (ie, inhalation, ingestion, and dermal absorption), exposure to this crystalline substance may occur from its use as vesicant or in the synthesis of citric acid. Effects from exposure may include contact burns to the skin and eyes, and even death with sufficiently high concentrations. In activities or situations where over exposure may occur, wear a self-contained breathing apparatus and chemical protective clothing which is specifically recommended by the shipper or producer. If contact should occur. immediately flush affected skin or eyes with running water for at least 15 minutes, and remove contaminated clothing and shoes at the site. While bischloromethyl ketone does not ignite easily, it may burn with the production of irritating and poisonous gases. Also, containers may explode violently in the heat of a fire. Fires involving bischloromethyl ketone may be extinguished with dry chemical, CO2, Halon, water spray, fog, or standard foam. Fight the fire from as far a distance as possible, and dike runoff from fire control water. Containers for international shipment by air and water must bear the labels, "Corrosive" and "Poison", respectively. Small spills of bischloromethyl ketone may be taken up and placed into containers for later disposal (liquid solutions are first absorbed by sand or other noncombustible material). Large liquid spills should be diked far ahead of the spill area for later disposal. Prior to implementing land disposal of bischloromethyl ketone, consult with environmental regulatory agencies for guidance.

A halogenated ketone. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

/GUIDE 153: SUBSTANCES - TOXIC and/or CORROSIVE (Combustible)/ Fire or Explosion: Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

/GUIDE 153: SUBSTANCES - TOXIC and/or CORROSIVE (Combustible)/ Health: TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

/GUIDE 153: SUBSTANCES - TOXIC and/or CORROSIVE (Combustible)/ Public Safety: CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover. As an 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. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate enclosed areas.

/GUIDE 153: SUBSTANCES - TOXIC and/or CORROSIVE (Combustible)/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.

PG II: the degree of danger presented by the material is medium

Releases of CERCLA hazardous substances are subject to the release reporting requirement of CERCLA section 103, codified at 40 CFR part 302, in addition to the requirements of 40 CFR part 355. Bis(chloromethyl) ketone is an extremely hazardous substance (EHS) subject to reporting requirements when stored in amounts in excess of its threshold planning quantity (TPQ) of 10/10,000 lbs.
