For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Aromatic hydrocarbons and related compounds

SECTION 5: Firefighting measures

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)

SECTION 10: Stability and reactivity

Reactivity

On combustion, forms irritating and toxic fumes including nitrogen oxides and carbon monoxide. Reacts vigorously with strong oxidants. This generates fire and explosion hazard. Attacks copper and copper alloys.

Chemical stability

no data available

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].

Persistence and degradability

BOD: (theoretical) 4.4%, 5 days; 56.6%, 20 days; 0.12-2.14 lb/lb, 5 days

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).

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).

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.

Contaminated packaging

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.
