Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing will only provide limited protection. (ERG, 2016)
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 permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. 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 be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|SRP: Contaminated protective clothing should be segregated in a manner that results in no direct personal contact by personnel who handle, dispose of, or clean the clothing. Quality assurance procedures to confirm the efficacy of the cleaning procedures should be implemented prior to the decontaminated protective clothing being returned for reuse by the workers. Contaminated clothing (including shoes/socks) should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5). /Ethylenebisdithiocarbamic acid, salts & esters/
Toxicity
/BIRDS and MAMMALS/ In birds, paralysis and muscular and peripheral nerve atrophy have ... been observed. /Dithiocarbamates/|/AQUATIC SPECIES/ Dithiocarbamates have an LC50 of less than 1 mg/L for invertebrates (Daphnia) and between 1 and 4 mg/L for algae (Chlorella). The acute toxicity of dithiocarbamates for fish is rather high. In general, the acute LC50 of dialkyldithiocarbamates for fish is less than 1 mg/L, and that of EBDCs is in the range 1-8 mg/L water. The sac fry and early fry stages of the rainbow trout have a higher sensitivity than other early life stages, and embryotoxic and teratogenic effects are induced by certain dithiocarbamates. However, bioaccumulation is low (bioconcentration factor < 100). The toxicity of /ethylenethiourea/ (ETU) and /ethyleneurea/ (EU) for fish, Daphnia, Chlorella, and two bacteria species is very low, of the order of g/L. /Dithiocarbamates/|/AQUATIC SPECIES/ ... The 60-day toxicity for early life stages was tested on S. gairdneri using a number of dialkyldithiocarbamates, EBDCs, and breakdown products. The LC50s ranged from approx 1 to 9 ug/L for dialkyldithiocarbamates and 211-2100 ug/L for EBDCs, but /ethylene thiourea/ (ETU) and /ethyleneurea/ (EU) were not toxic, even at levels exceeding 1000 mg/L.|/AQUATIC SPECIES/ Embryotoxic and teratogenic effects were also observed for all the /dithiocarbamate/ compounds studied, and there was an overlap between the responses for skeletal malformations and lethality over a wide concentration range. The teratogenic effects in rainbow trout proved to be in agreement with those observed in mammals. Exposure of rainbow trout during embryo-larval development revealed that malformations induced by dithiocarbamates were almost exclusively confined to the notochord, which increased considerably in both length and diameter. As a result, the notochord became twisted and distorted. Ectopic osteogenesis was observed in almost every affected notochord. Other effects, such as the disruption of the integrity of myomeres and organ dislocations, were closely related to the notochordal anomalies. Also, compression and fusion of vertebrae and "waviness" of various skeletal elements were found. Concentration-related changes in the liver were observed in short-term exposure of juvenile rainbow trout, while at high levels proliferation of bile duct epithelial cells and necrosis of hepatocytes were seen. /Dithiocarbamates/|/AQUATIC SPECIES/ Short-term toxicity studies using /dithiocarbamate/ compounds ... were carried out to investigate the effects of prolonged exposure (21-day) on survival, fecundity, and growth of Daphnia magna. Growth and reproduction were not specifically inhibited, since effects on these characteristics were generally detected at levels comparable with the 21-day LC50s. For dialkyldithiocarbamates, the 21-day LC50s ranged from approx 10 to 30 ug/L, for EBDCs, from 80 to 110 ug/L, and, for ETU /(ethylenethiourea)/ and EU /(ethyeleneurea)/, the levels were 18 and 3200 mg/L, respectively ... /Dithiocarbamates/
Ethylene bis(dithiocarbamic acid)'s production may result in its release to the environment through various waste streams; its use in the heavy metal salt form as a fungicide(1) will result in the acid's direct release to the environment(SRC).
TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 600(SRC), determined from a structure estimation method(2), indicates that ethylene bis(dithiocarbamic acid) is expected to have low mobility in soil(SRC). The estimated pKa of ethylene bis(dithiocarbamic acid) is 5.11(3), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of ethylene bis(dithiocarbamic acid from moist soil surfaces is not expected to be an important fate process(SRC) given its pKa(3). Ethylene bis(dithiocarbamic acid) is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 7.5X10-8 mm Hg(2). No biodegradation data are available(SRC, 2010).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 600(SRC), determined from a structure estimation method(2), indicates that ethylene bis(dithiocarbamic acid) is expected to adsorb to suspended solids and sediment(SRC). An estimated pKa of 5.11(3) indicates ethylene bis(dithiocarbamic acid) will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow of -2.7(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). The hydrolysis half-life of ethylene bis(dithiocarbamic acid) was reported as 69 hours at pH 7(8). No biodegradation data are available(SRC, 2010).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethylene bis(dithiocarbamic acid), which has a vapor pressure of 7.5X10-8 mm Hg at 20 °C(2) will exist solely in the particulate phase in the ambient atmosphere. Particulate-phase ethylene bis(dithiocarbamic acid) may be removed from the air by wet or dry deposition(SRC). Ethylene bis(dithiocarbamic acid) contains chromophores that absorb at wavelengths >290 nm(3) and therefore may be susceptible to direct photolysis by sunlight(SRC).
The rate constant for the vapor-phase reaction of ethylene bis(dithiocarbamic acid) with photochemically-produced hydroxyl radicals has been estimated as 2.1X10-10 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 2 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The hydrolysis half-life of ethylene bis(dithiocarbamic acid) was reported as 69 hours at pH 7(2). Ethylene bis(dithiocarbamic acid) contains chromophores that absorb at wavelengths >290 nm(3) and therefore may be susceptible to direct photolysis by sunlight(SRC).
An estimated BCF of 3 was calculated in fish for ethylene bis(dithiocarbamic acid)(SRC), using a log Kow of -2.7(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).
549.54 L/kg|Using a structure estimation method based on molecular connectivity indices(1), the Koc of ethylene bis(dithiocarbamic acid) can be estimated to be 600(SRC). According to a classification scheme(2), this estimated Koc value suggests that ethylene bis(dithiocarbamic acid) is expected to have low mobility in soil.
An estimated pKa of 5.11(1) indicates ethylene bis(dithiocarbamic acid) will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces and moist soil is not expected to be an important fate process(2). Ethylene bis(dithiocarbamic acid) is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 7.5X10-8 mm Hg(3).
Ethylene bis(dithiocarbamic acid) was detected in 10 domestic food products in the US at a max concn of 3 ppm(1). In 282 samples of 22 food commodities, 0.7-4.8 ppm of ethylene bis(dithiocarbamic acid) were detected(2).
Occupational exposure to ethylene bis(dithiocarbamic acid) may occur through inhalation and dermal contact with this compound at workplaces where ethylene bis(dithiocarbamic acid) is produced or used. Monitoring data indicate that the general population may be exposed to ethylene bis(dithiocarbamic acid) via ingestion of food containing residual fungicide. (SRC)
Drug Information
Dithiocarbamates have ... been used to control various dermatophytes ... For example, tetramethylthiuram disulfide, incorporated in various soaps and lotions, has been used since 1942 for the treatment of scabies and other parasitic diseases of the skin in veterinary and human medicine ... Dithiocarbamates also have considerable biocidal activity against a number of protozoa. /Dithiocarbamates/
As a general rule, dithiocarbamates can be absorbed by the organism via the skin, mucous membranes, and the respiratory and gastrointestinal tracts. /Dithiocarbamates/
Dithiocarbamates may decompose under certain circumstances into a number of compounds, such as sulfur, 5,6-dihydro-3 H-imidazol [2,1-C]-1,2,4-dithiazole-3-thione, ethylenethiourea (ETU), and ethylenediamine (EDA). ETU is fairly stable, has a high water solubility, and is of particular importance because of its specific toxicity. /Dithiocarbamates/|The metabolic decomposition of EBDCs in mammals is complex and results in the formation of carbon disulfide, /ethylene diamine/ (EDA), a few ethylene bisthiuram disulfides, hydrogen sulfide, ethylene bisthiocyanate, and /ethylene thiourea/ (ETU). The latter is further broken down to moieties that are incorporated into compounds such as oxalic acid, glycine, urea, and lactose. Dithiocarbamates and their metabolic products are found in certain organs, such as the liver, kidneys, and, especially, the thyroid gland, but accumulation of these compounds does not take place because of their rapid metabolism. After treating plants with dithiocarbamates, a large number of metabolites are found, including ETU, /ethylene urea/ (EU), imidazole derivatives, diisothiocyanates, diamines, disulfides, and other metabolites, that are still unknown. /Dithiocarbamates/
Ethylenethiourea contents of ethylenebisdithiocarbamate formulations (carcinogenic and teratogenic fungicides) were determined by reversed phase chromatography. The method was simple, rapid (25 min) and allowed control of analysis time to minimize ethylenethiourea formation from intermediary degradation products in soln. Analyzed products contained less than 0.2% ethylenethiourea except for greater than 3 yr old formulations. /Ethylenebisdithiocarbamate formulations/
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)
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. (ERG, 2016)
/SRP:/ Immediate first aid: Remove patient from contact with the material. 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. /Dithiocarbamates and Related Compounds/|/SRP:/ Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal ... . /Dithiocarbamates and Related Compounds/|/SRP:/ Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious or is in severe respiratory distress. Use moderate hyperventilation (rate of 20 respirations per minute) if signs of cerebral edema are present. Monitor cardiac rhythm and treat arrhythmias if necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if patient is hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Treat seizures with diazepam or lorazepam ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Dithiocarbamates and Related Compounds/|Gastrointestinal decontamination. If a large amount of the fungicide has been ingested in the last few hours, and if copious vomiting has not already occurred, it may be reasonable to consider GI decontamination. Activated charcoal can be used along with the addition of the cathartic sorbitol to the charcoal slurry. If sorbitol is given separately, it should be diluted with an equal volume of water before administration. No more than one dose of sorbitol is recommended and it should be used with caution in children and the elderly. If contact with the toxicant has been minimal (for example, oral contamination only, promptly flushed out of the mouth), administration of charcoal without a cathartic, followed by careful observation of the patient, probably represents optimal management. /Ethylene bis dithiocarbamates (EBDC compounds)/|For more Antidote and Emergency Treatment (Complete) data for Ethylenebisdithiocarbamic acid (6 total), please visit the HSDB record page.
