5.Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: SMALL FIRE: Dry chemical, CO2 or water spray. LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)

10.3 Possibility of hazardous reactions
Flammable when exposed to heat or flame ... .The vapour is heavier than air.2-METHYL-5-ETHYLPYRIDINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. A mixture of nitric acid and methyl ethyl pyridine was placed in an autoclave and heated and stirred for 40 minutes. The emergency vent opened due to a sudden pressure rise, then an explosion occurred after about 90 seconds [Chem. Eng. News 30:3348. 1952].

12.2 Persistence and degradability
BOD: (theoretical) 4.4%, 5 days; 56.6%, 20 days; 0.12-2.14 lb/lb, 5 days
12.3 Bioaccumulative potential
An estimated BCF of 14 was calculated for 2-methyl-5-ethylpyridine(SRC), using an estimated log Kow of 2.4(1,SRC) 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 2-methyl-5-ethylpyridine can be estimated to be 170(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-methyl-5-ethylpyridine is expected to have moderate mobility in soil. The pKa of 2-methyl-5-ethylpyridine is 6.51(3), which indicates that this compound will exist in the protonated form under acidic and neutral conditions. Cations adsorb more strongly to soil surfaces than neutral molecules thus adsorption of 2-methyl-5-ethylpyridine may be greater in acidic and neutral soils(SRC).
12.5 Other adverse effects
no data available
13.Disposal considerations
