4.2 Most important symptoms/effects, acute and delayedExcerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryImmediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Organic acids and related compounds/
5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaThis chemical is a combustible liquid, but does not readily ignite. Poisonous gases include phosgene, hydrogen chloride, carbon monoxide are produced in fire. Use dry chemical, carbon dioxide, or alcohol or foam extinguishers. Vapors may travel long distances to ignition sources and flashback. Vapors in confined area may explode in fire. Storage containers and parts of containers may rocket great distances, in many directions. If materials 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.
5.2 Specific hazards arising from the chemicalExcerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. 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)
5.3 Special protective actions for fire-fightersWear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures 6.1 Personal precautions, protective equipment and emergency proceduresUse personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautionsPersonal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Cautiously neutralize remainder. Then wash away with plenty of water.
6.3 Methods and materials for containment and cleaning upEvacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete. Remove all ignition sources. Ventilate area of spill or leak. Absorb liquids in vermiculite, dry sand, earth, or a similar non-organic materials and deposit in sealed containers. Keep this chemical out of a confined space, such as a sewer, because of the possibility of an explosion, unless the sewer is designed to prevent the build-up of explosive concentrations. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. If employees are required to clean-up spills, they must be properly trained and equipped.
7.Handling and storage 7.1 Precautions for safe handlingAvoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.
7.2 Conditions for safe storage, including any incompatibilitiesSeparated from metals, combustible substances, reducing agents, strong oxidants, strong bases and food and feedstuffs. Well closed. Ventilation along the floor.Prior to working with dichloroacetic acid you should be trained on its proper handling and storage. Store in tightly closed containers in a cool, well-ventilated area away from incompatible materials listed above. Metal containers involving the transfer of this chemical should be grounded and bonded. Where possible, automatically pump liquid from drums or other storage containers to process containers. Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only non-sparking tools and equipment, especially when opening and closing containers of this chemical. Sources of ignition such as smoking and open flames are prohibited where ethylene oxides is handled, used, or stored in a manner that could create a potential fire or explosion hazard. Wherever this chemical is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fitting.

AEROBIC: The biodegradability of dichloroacetic acid, at 10 ppm, was measured in both river water and seawater using the cultivation method; 14 and 8% degradation was reported for river water and seawater, respectively, after 3 days incubation(1). Based on these results, this compound was determined to be difficult to degrade(1). 0, 27, and 68% of the theoretical BOD in a BOD test was reached in 2, 5, and 10 days, respectively, following inoculation with sewage(2). Dichloroacetic acid was not biodegraded during a 5 day BOD test using a sewage inoculum(3). Dichloroacetic acid at 20 mg/L was >95% degraded in a 20 day BOD test; in a second screening test, this compound was 83% degraded after 30 days(4). Dichloroacetic acid, present at 100 mg/L, reached 97% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(5). Pure culture experiments show that aerobic degradation occurs via dehalogenation(6).
12.3 Bioaccumulative potentialAn estimated BCF of 3.2 was calculated for dichloroacetic acid(SRC), using a log Kow of 0.92(1) 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 soilThe Koc of dichloroacetic acid is estimated as 75(SRC), using a log Kow of 0.92(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that dichloroacetic acid is expected to have high mobility in soil. The pKa of dichloroacetic acid is 1.26(4), indicating that this compound will primarily exist in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
