5.2 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)
5.3 Special protective actions for fire-fighters
Use alcohol-resistant foam, powder, carbon dioxide.

Decomposes on burning. This produces irritating fumes. Reacts with oxidants.
10.2 Chemical stability

10.3 Possibility of hazardous reactions
FIRE HAZARD: Moderate, when exposed to heat or flame.METHYL ACETOACETATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides

12.2 Persistence and degradability
AEROBIC: Methyl acetoacetate, present at 100 mg/L, reached 78% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). Methyl acetoacetate was degraded more than 90% in 2 days at 22 deg C using activated sludge inoculum in a Zahn-Wellens screening test(2).
12.3 Bioaccumulative potential
An estimated BCF of 3.1 was calculated for methyl acetatoactate(SRC), using an estimated log Kow of -0.69(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).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for methyl acetoacetate can be estimated to be 1.0(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl acetoacetate is expected to have very high mobility in soil.
12.5 Other adverse effects
no data available
SECTION 13: Disposal considerations
13.1 Disposal methods
Product
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.
