Fire Hazards · 2 items

When heated to decomposition, it emits highly toxic fumes of chlorides. This material may burn but does not ignite readily. Container may explode in heat of fire. (EPA, 1998)

· Combustible material: may burn but does not ignite readily.

Health Hazards · 2 items

It may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases. Runoff from fire control or dilution water may cause pollution. (EPA, 1998)

· TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury or death.

Hazards Summary · 1 item

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.

Safety & protection

Fire Fighting · 1 item

Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Wear positive pressure breathing apparatus and special protective clothing. Remove and isolate contaminated clothing at the site. If water pollution occurs, notify appropriate authorities.

Accidental Release Measures · 2 items

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

First Aid · 2 items

Warning: Bis(chloromethyl) ketone may be fatal if inhaled, swallowed, or absorbed through skin.
