Specific Hazards Arising from the Chemical
Excerpt from ERG Guide 127 [Flammable Liquids (Water-Miscible)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)
Advice for firefighters
Use alcohol-resistant foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Personal precautions, protective equipment and emergency procedures
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Collect leaking and spilled liquid in sealable metal (mild steel) containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.
Environmental precautions

Collect leaking and spilled liquid in sealable metal (mild steel) containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.
Methods and materials for containment and cleaning up
Evacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete. Remove all ignition sources. Establish forced ventilation to keep levels below explosive limit. Absorb liquids in vermiculite, dry sand, earth, peat, carbon, or similar material and deposit in sealed containers. Keep this chemical out of a comfined space ... because of the possibility of an explosion ... It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. If employees are required to clean up spills, they must be properly trained and equipped. OSHA 1910.120(q) may be applicable.
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof. Separated from oxidants.Diethyl ketone must be stored to avoid contact with oxidizing materials (such as peroxides, perchlorates, chlorates, permanganates, and nitrates) Since violent reactions may occur. Store in tightly closed containers in a cool, well ventilated area away from sources of heat. Sources of ignition such as smoking and open flames are prohibited where diethyl ketone is handled, used or stored in a manner that could create a potential fire or explosion hazard. Metal containers involving the transfer of 5 gallons or more of diethyl ketone should be grounded and bonded. Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only non-sparking tools and equipment, especially when opening and closing containers of diethyl ketone. Wherever this diethyl ketone is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings.

Persistence and degradability
AEROBIC: Several investigators have shown that diethyl ketone readily biodegrades in screening tests using sewage or sludge(1-5). Using a standard BOD dilution technique and acclimated sewage inocula, a BOD of 66.4%(1) and 89%(2) of theoretical was observed over a 5 day incubation period. Using a standard BOD dilution technique and unacclimated sewage inocula, BOD values of 50.8%(3) and 38%(4) of theoretical was observed over a 10 day incubation period. The percent theoretical BOD of diethyl ketone in a semi-continuous activated sludge (SCAS) biological treatment simulation test was 38% over a 24 hour incubation period(5).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for diethyl ketone(SRC), using a log Kow of 0.99(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of diethyl ketone is estimated as 82(SRC), using a log Kow of 0.99(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that diethyl ketone is expected to have high mobility in soil.
Other adverse effects
