Specific hazards arising from the chemical
Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: Combustible material: may burn but does not ignite readily.

Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. (ERG, 2016)
Special protective actions for fire-fighters
Use carbon dioxide, powder, water spray.

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating. This produces carbon monoxide and vinyl chloride. Reacts violently with strong oxidants and strong bases.
Chemical stability
no data available
Possibility of hazardous reactions
COMBUSTIBLE /DICHLOROTOLUENE/As a result of flow, agitation, etc., electrostatic charges can be generated.Simple aromatic halogenated organic compounds, such as 2,4-DICHLOROTOLUENE, are very unreactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Persistence and degradability
2,4-Dichlorotoluene was found to be susceptible to anaerobic metabolism in soil slurry microcosms under methanogenic conditions. 2,4-Dichlorotoluene, at an initial concentration of 800 uM was completely degraded after 130 days; 50% degradation required about 90 days. The predominant product of this reaction was 4-chlorotoluene, a small amount of 2-chlorotoluene was also produced(1).[(1) Ramanand K et al; Appl Environ Microbiol 59: 3266-3272 (1993)] Full text: PMC182447
Bioaccumulative potential
An estimated BCF value of 1000 was calculated for 2,4-dichlorotoluene(SRC), using a measured log Kow of 4.24(1) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will be an important fate process(SRC).
Mobility in soil
The Koc of 2,4-dichlorotoluene is estimated as approximately 4,800(SRC), using a measured log Kow of 4.24(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that 2,4-dichlorotoluene will have only slight mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
