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)
Advice for firefighters
Use alcohol-resistant foam, powder, carbon dioxide.
NFPA 704
| HEALTH | 2 | Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury (e.g. diethyl ether, ammonium phosphate, iodine) | |
| FIRE | 2 | Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur) | |
| REACT | 0 | Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2) | |

Possibility of hazardous reactions
It/ does not form flammable mixtures with air at room temperature.ACETOPHENONE reacts with many acids and bases liberating heat and flammable gases (e.g., H2). Reacts with many oxidizing agents. Reacts with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. The amount of heat in these reactions may be sufficient to start a fire in the unreacted portion. Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides.

The substance is irritating to the eyes. The substance may cause effects on the central nervous system.
STOT-repeated exposure
The substance defats the skin, which may cause dryness or cracking.
Aspiration hazard
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
Toxicity

- Toxicity to microorganisms: IC50 - activated sludge - > 1 000 mg/L - 3 h. Remarks:Respiration rate.
Persistence and degradability
Acetophenone, present at 100 mg/l, achieved 61-68% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/l and the Japanese MITI test(1). Other screening studies give similar results and acetophenone is confirmed to be biodegradable(2-4). Acetophenone achieved 20-32% of its theoretical BOD using a sewage inoculum over a 5 day incubation period(2,3). Acetophenone reached 59% of its theoretical BOD using acclimated mixed microbial cultures and a 5 day incubation period(4). The biodegradation half-lives of acetophenone in groundwater, river water and lake water were 32, 8 and 4.5 days, respectively(5,6).
Bioaccumulative potential
An estimated BCF of 0.5 was calculated for acetophenone(SRC), using a log Kow of 1.58(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 acetophenone was measured as 10, using an agricultural soil obtained from Northeastern China(1). According to a classification scheme(2), this Koc value suggests that acetophenone is expected to have very high mobility in soil(SRC).
Other adverse effects
