5.2 Specific hazards arising from the chemical
Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]: 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)
5.3 Special protective actions for fire-fighters
Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures

6.2 Environmental precautions
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. 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.
6.3 Methods and materials for containment and cleaning up
1. remove all ignition sources. 2. ventilate area of spill or leak. 3. for small quantities, absorb on paper towels. evaporate in a safe place (such as a fume hood). allow sufficient time for evaporating vapors to completely clear the hood ductwork. burn the paper in a suitable location away from combustible materials.liquid sec-hexyl acetate should not be allowed to enter a confined space, such as a sewer, because of the possibility of an explosion.

10.1 Reactivity
Reacts with strong oxidants.
10.2 Chemical stability
no data available
10.3 Possibility of hazardous reactions
MODERATE FIRE RISK.METHYLAMYL ACETATE 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. This compound is incompatible with the following: Nitrates; strong oxidizers, alkalis & acids (NIOSH, 2016).

In aerobic screening tests using an unacclimated sewage seed, 4-methyl-2-pentyl acetate reached 20, 87, 62 and 69% of its theoretical BOD after 5, 10, 15, and 20 days, respectively in freshwater(1). In aerobic screening tests using synthetic seawater with added raw wastewater, 4-methyl-2-pentyl acetate reached 11, 22, 52, and 67% of its theoretical BOD after 5, 10, 15, and 20 days, respectively(1).
12.3 Bioaccumulative potential
An estimated BCF of 66 was calculated for 4-methyl-2-pentyl acetate(SRC), using an estimated log Kow of 2.7(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF suggests that bioconcentration in aquatic organisms is moderate, not high(SRC).
