Alcohol foam, dry chemical or carbon dioxide
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)
Special protective actions for fire-fighters
Use alcohol-resistant foam, carbon dioxide, powder. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Environmental precautions
Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
Remove all ignition sources. Ventilate area of spill or leak. For small quantities of liquids containing cyclohexanone, absorb on paper towels and place in an appropriate container. Place towels in a safe place (such as a fume hood) for evaporation. Allow sufficient time for evaporation of the vapors so that the hood ductwork is free from cyclohexanone vapors. Burn the paper in a suitable location away from combustible materials.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Above 44°C use a closed system, ventilation and explosion-proof electrical equipment. Prevent build-up of electrostatic charges (e.g., by grounding). 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 strong oxidants.Keep containers closed; prohibit open flame. Store in cool and dark plane.

Persistence and degradability
Cyclohexanone is readily biodegradable according to most aerobic screening tests reported in the literature. Cyclohexanone was found to be significantly biodegradable using the Japanese MITI test protocol(3,4). The Japanese Chemical Testing and Inspection Institute obtained 97% of theoretical BOD in a 4-week test using 100 mg/L test concentration and a 30 mg/L sludge inoculum(1). A 5-day 32% theoretical BOD was determined using the AFNOR T 90/103 test (screening biodegradation test) and microbes from 3 polluted surface waters(5). A 96% removal (based on COD) in a mineral salts solution was observed using an acclimated activated sludge inoculum(6). Five-day BODs of 68.2% and 62.4% of theoretical were obtained using standard and seawater dilution methods, respectively(7). In Warburg respirometer studies, 50% of theoretical BOD was observed in 20 and 50 hours using adapted and nonadapted cultures, respectively(8). Fifty percent of theoretical BOD was obtained in a 5-day test using mixed microbial cultures(2).
Bioaccumulative potential
The bioconcentration factor (BCF) for cyclohexanone can be estimated to be 2.4 based on the log Kow of 0.81(1) and a recommended regression equation(2). This BCF indicates that cyclohexanone will not bioconcentrate in aquatic organisms(SRC).
Mobility in soil
The Koc for cyclohexanone estimated using structure activity relationships (SAR) is 15(1). A Koc of 17 can be estimated from the water solubility, 23,000 mg/L(2), using a recommended regression equation(3). According to a suggested classification scheme(4), these Koc values indicate that cyclohexanone will be highly mobile in soil.
Other adverse effects
no data available
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.
