SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a POTW is acceptable only after review by the governing authority. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must meet Hazardous Material Criteria for disposal.
NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Separated from acids. Keep in a well-ventilated room.Store above 40 deg F, away from feed, foodstuffs, or any body of water.

Dicofol or kelthane is a white crystalline, wettable powder dissolved in a liquid carrier, (water). The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams. It can cause illness by inhalation, skin absorption, and/or ingestion. It is used as a pesticide.

Liquid solvent may be flammable.DICOFOL is an organochlorine bridged diphenyl. Halogenated aliphatic compounds are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms are replaced with halogen atoms. Halogenated aliphatics are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. DICOFOL hydrolyzes in alkali. It is slightly corrosive to metals. Contact with steel at elevated temperatures causes formation of toxic gases. (NTP, 1992).

The substance is irritating to the eyes and skin (technical grade). The substance may cause effects on the central nervous system, liver and kidneys.
Repeated or prolonged contact with skin may cause dermatitis.
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
AEROBIC: Dicofol, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Dicofol degraded with a half-life of 43 days in a silt loam soil(2). The major metabolites were 1,1-(p-chlorophenyl)-2,2-dichloroethanol, p,p'-DCBP, and 3-hydroxy-4,4'-dichlorobenzophenone(2). Volatile residues were 21-22% of the applied, and unextractable residues were 10-15% of the applied after 12 months(2). In a different study, the aerobic biodegradation half-life of dicofol in soil is expected to range from 259 to 348 days based upon a 300 day open bottle experiment with mixed soil (conducted indoors) and a 300 day open bottle experiment with surface soil (conducted outdoors), respectively(3).
BCFs of 8200 and 6100 were measured in carp (Coprinus carpio) exposed for a 60 day incubation period at concns of 1.0 and 0.1 ug/L of dicofol, respectively(1). The BCF of dicofol was measured as 15,000, 18,900, 9,500 and 14,500 in fathead minnow at dicofol concns of 12.38, 1.15, 14.95 and 1.33 ppb, respectively(2). Dicofol residues accumulated in bluegill sunfish with BCFs of 6,600, 17,000, and 10,000 in fillet, viscera, and whole fish, respectively, during 28 days of exposure(3). The estimated elimination half-life was 33 days(3). BCFs in fish were reported as 8050-13,500 based on whole body weight(4). According to a classification scheme(5), these BCF values suggest the potential for bioconcentration in aquatic organisms is very high. In crop areas, the highest mean concns of dicofol measured in the biotic matrices were 1.4 ppm for small mammals (FL), 3.9 ppm for terrestrial invertebrates (CA), and 3.8 ppm for reptiles/amphibians (FL)(3). In non-crop areas, highest mean concns were 0.3 ppm for small mammals (NY), 0.76 ppm for terrestrial invertebrates (FL), 0.38 ppm for reptiles/amphibians (FL), 0.9 ppm for birds (FL), and 0.26 ppm for fish (FL)(3).
The Koc for dicofol is 8,383 in sand, 8,073 in sandy loam, 5,868 in silty loam, and 5,917 in clay loam(1). Other reported Koc values for dicofol are 7,207 in sand (0.2% organic matter, pH 6.5), 6,945 in sandy loam (1.6% organic matter, pH 5.8), 5,017 in silty loam (2.4% organic matter, pH 7.1), and 5,086 in clay loam (2.8% organic matter, pH 7.0)(2). Dicofol shows moderate to low mobility in batch equilibrium and column leaching studies, with little potential to leach to groundwater(3). In batch equilibrium studies, mobility of dicofol was moderate in sand (Koc of 5,868), and clay loam (Koc of 5,917) soil slurries(3). According to a classification scheme(4), these Koc values suggest that dicofol is expected to be immobile in soil.

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.
