Specific hazards arising from the chemical
Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: 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. Substance may be transported hot. For hybrid vehicles, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. If molten aluminum is involved, refer to ERG Guide 169. (ERG, 2016)
Special protective actions for fire-fighters
Use powder, AFFF, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Collect leaking liquid in sealable containers. 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
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
SECTION 7: Handling and storage

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Oncorhynchus mykiss (previous name: Salmo gairdneri) - > 100 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - > 100 mg/L - 48 h.

- Toxicity to microorganisms: EC50 - activated sludge of a predominantly domestic sewage - > 1 000 mg/L - 3 h.
Persistence and degradability
Pure culture studies showed various isolated species of bacteria(1,2) and yeast(3) were unable to utilize cyclopentanone as a single carbon source. A single 5-day BOD screening test, which utilized activated sludge for inocula, indicates cyclopentanone biodegraded rapidly with acclimation(4). After a 20 day acclimation period. 95.4% COD of an initial concn of 100 mg/L was removed in a closed bottle maintained at 20 deg C and a pH of 7.2(4).
Bioaccumulative potential
Based upon an estimated log kow of 0.24(1), the bioconcentration factor (log BCF) for cyclopentanone has been calculated to be -0.05, from a recommended regression-derived equations(2). This BCF value indicates cyclopentanone should not bioconcentrate in aquatic organisms(SRC).
Mobility in soil
Based on an estimated water solubility of 9175 mg/L(1), a Koc value of 30 for cyclopentanone has been calculated from a regression-derived equation(1,SRC). This Koc value indicates cyclopentanone should be very highly mobile in soil(2).
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.
