SECTION 5: Firefighting measures
Suitable extinguishing media
This chemical is not flammable, but may support combustion. Stay upwind of fire. Use dry chemical, carbon dioxide, water spray, or foam extinguishers. Poisonous gases are produced in fire including nitrogen oxides and chlorine. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors, or shows any signs of deforming), withdraw immediately to a secure position. If employees are expected to fight fires, they must be trained and equipped in OSHA 1910.156. If employees are expected to fight fires, they must be trained and equipped in OSHA 1910.156.

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and on burning. This produces toxic fumes including hydrogen chloride (see ICSC 0163) and nitrogen oxides. Reacts with strong oxidants. Corrosive to iron and steel.
Chemical stability
Indefinitely stable; not sensitive to light or heat
Possibility of hazardous reactions
Dust explosion possible if in powder or granular form, mixed with air.A halogenated acetamide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Conditions to avoid
no data available
Incompatible materials
Strong oxidizers. Corrosive to iron and steel.
Hazardous decomposition products
When heated to decomposition it emits very toxic fumes of /hydrogen chloride and nitrogen oxides/.

- Toxicity to microorganisms: no data available
Persistence and degradability
Soil incubation studies suggests that alachlor is biodegraded rapidly in soils but that very little ring-labeled (14)c alachlor is converted to (14)co2. majority of radioactivity could be recovered from soil only after alkaline hydrolysis, suggesting that herbicidal metabolites were bound to soil org matter. ... 2-chloro-2',6'-diethylacetamide was formed in alachlor-treated air-dried soils incubated @ 46 deg c. this product ... believed to result ... from acid-catalyzed hydrolysis ... on mineral surfaces.
Bioaccumulative potential
Biological concentration factors of 2.8 and 10.3 mg/L were measured in fish for alachlor, using bluegill sunfish which were exposed in an ecosystem treated with 2.5 and 10.3 kg/ha, respectively; substantial amounts of residue were present in fish up to 20 days(1). Whole body bioconcentration factor (BCF) for alachlor in fathead minnow (Pimephales promelas) was measured to be 6(2). According to a classification scheme(3), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC). Alachlor was rapidly eliminated upon transfer of fish in uncontaminated water with 81% and 98% being eliminated after 24 hr and 14 days, respectively(2). This rapid elimination was also found in rainbow trout (Salmo gairdneri)(2).
Mobility in soil
Log Koc values for alachlor have been reported by various authors to range 2.08 (Koc = 120) to 3.33 (Koc = 2,138)(1,2). According to a classification scheme(3), this estimated Koc value suggests that alachlor is expected to have high to low mobility in soil(3). Experimental results confirm that alachlor adsorbs weakly to moderately to soil and the leaching of alachlor from soil is high to medium(4,5). The adsorption of alachlor increases with an increase in organic content, clay content and surface area of soil(4). Alachlor was not detected in groundwater from a soil with high organic and clay content(5). This is probably due to longer residence time in this soil allowing the degradation of alachlor before it reached the water table. The presence of continuous pores or channels in soil will increase the mobility of alachlor in soil(6,7).
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.
