If inhaled
Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Following skin contact
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Following eye contact
Rinse with pure water for at least 15 minutes. Consult a doctor.
Following ingestion
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
4.2 Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. (ERG, 2016)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Bath and shampoo with soap and water to remove chemicals from skin and hair. Obtain medical treatment if irritation persists. Individuals with chronic skin disease or known sensitivity to these herbicides should either avoid using them or take strict precautions to avoid contact (respirator, gloves, etc). Flush contaminating chemicals from eyes with copious amounts of clean water for 10-15 minutes. If irritation persists, obtain medical treatment. Chlorophenoxy cmpd
SECTION 5: Fire-fighting measures
5.1 Suitable extinguishing media
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal. FIRE INVOLVING TANKS: 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)
5.2 Specific hazards arising from the chemical

12.2 Persistence and degradability
In soil, the rate of hydrolysis of dichlorfop-methyl followed the order pH 6.4>7.5>5.5(1). Dichlorfop-methyl appears to be hydrolyzed in soil by hydrolase enzymes associated with viable microorganisms(1). As established in model ecosystems or by direct measurements of soils or waters, dichlorfop-methyl undergoes decarboxylation and ether cleavage reactions in biological systems(2). Dichlorfop-methyl undergoes rapid microbial hydrolysis of the ester bond(3). Dichlorfop, the corresponding acid, was formed and was extensively degraded under aerobic conditions, the final product being CO2(3). Under anaerobic conditions, the degradation proceeded to a small extent, at most, where 3% of the applied radioactivity is accounted for by the degradation product 4-(2,4-dichlorophenoxy)phenol(3). No other metabolite, including CO2 was observed implying a lack of any further degradation(3). In a degradation study of dichlorfop-methyl in moist non-sterile heavy clay, silty clay, and sandy loam soils, an initial and rapid hydrolysis to the corresponding acid was followed by a much slower hydrolytic process so that traces of the ester could still be seen after 10 weeks(4). Dichlorfop-methyl showed significantly more degradation in the presence of nonsterile sediment than in the presence of sterile sediment(5). It also biodegraded faster in the presence of sediment than in water alone(5). No racemization of the ester takes place upon hydrolysis in soil, but inversion of configuration of the hydrolysis products is observed (the S-configuration showed a higher inversion tendency than the R-configuration)(6).
12.3 Bioaccumulative potential
Based upon an experimental water solubility of 3 mg/l(1), the BCF of dichlorfop-methyl can be estimated to be approximately 300 from a regression-derived equation(2). This estimated BCF value suggests moderate bioconcentration in aquatic organisms(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indexes, the Koc for dichlorfop-methyl can be estimated to be about 4000(1). The Koc for dichlorfop-methyl can be estimated to be about 2400 based on an estimated water solubility of 3 mg/L(3) and a regression derived equation(2). Koc for dichlorfop-methyl has also been determined to be 16,000(4). According to a suggested classification scheme(5), these estimated and experimental Koc values suggest that dichlorfop-methyl will be slightly mobile to immobile in soil.
12.5 Other adverse effects
no data available
SECTION 13: Disposal considerations
13.1 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. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
