The major hazards encountered in the use and handling of fluoroacetamide stem from its toxicologic properties. Exposure to this colorless, crystalline powder may occur from its manufacture, formulation, and use as a rodenticide. Effects from exposure may include nausea, convulsions, cyanosis, ventricular fibrillation, and death. Effects may be delayed up to 20 hours following exposure. If contact should occur, remove clothing and vigorously wash skin, hair, and nails with soap. Fluoroacetamide should be stored in closed containers in a cool, closed area.

P057; As stipulated in 40 CFR 261.33, when fluoroacetamide, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to federal and/or state hazardous waste regulations. Also defined as a hazardous waste is any container or inner liner used to hold this waste or 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(e)).

In 1988, Congress amended FIFRA to strengthen and accelerate EPA's reregistration program which applies to each registered pesticide product containing an active ingredient initially registered before November 1, 1984. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA '88 were divided into three lists based upon their potential for exposure and other factors, with List B being of highest concern and D of least. List: C; Case: fluoroacetic acid derivatives; Case No.: 3073; Pesticide type: insecticide, rodenticide; Case Status: RED Approved 6/95; OPP has made a decision that some/all uses of the pesticide are eligible for reregistration, as reflected in a Reregistration Eligibility Decision (RED) document. ; Active Ingredient (AI): fluoroacetamide; AI Status: The active ingredient is no longer contained in any registered products. Thus, we characterize it as "cancelled.".

FLUOROACETAMIDE is a fluorinated amide. 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).

This compound is not very flammable but any fire involving this compound may produce dangerous vapors. You should evacuate the area. All firefighters should wear full-body protective clothing and use self-contained breathing apparatuses. You should extinguish any fires involving this chemical with a dry chemical, carbon dioxide, foam, or halon extinguisher. (NTP, 1992)

Use water spray, powder, foam, carbon dioxide.

Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give a slurry of activated charcoal in water to drink. Refer for medical attention .

Caution : Fluoroacetamide is extremely toxic. There is no known antidote. Immediately transport victims to a health care facility. Highly toxic fumes of fluorine-containing compounds and nitrogen oxides will be emitted when fluoroacetamide is heated to decomposition. Avoid sources of extreme heat including fire.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number P057, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.

A potential candidate for rotary kiln incineration at a temperature range of 820 to 1,600 °C and residence times of seconds for liquids and gases, and hours for solids. A potential candidate for fluidized bed incineration at a temperature range of 450 to 980 °C and residence times of seconds for liquids and gases, and longer for solids.

Remove all ignition sources. Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. Carefully collect remainder.

Consider gastric lavage after ingestion, and/or administer charcoal as a slurry. In case of refractory seizures after following ingestion, consider continuous infusion of midazolam, propofol, and/or pentobarbital. Hyperthermia, lactic acidosis and muscle destruction may necessitate use of neuromuscular blocking agents with continuous EEG monitoring. If the exposure occurred through inhalation, move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. In case of acute lung injury, maintain ventilation and oxygenation and evaluate with frequent arterial blood gas or pulse oximetry monitoring. Following eye exposure, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. In case of dermal exposure, Remove contaminated clothing and wash exposed area thoroughly with soap and water. (T36)

Metabolic acidosis, hyperglycemia, hyperuricemia, elevated serum levels of hepatic transaminases, and elevated serum creatinine levels may occur. Tachycardia, ventricular tachycardia or fibrillation, and sudden onset of asystole may occur (T36).

TERRESTRIAL FATE: Based on a classification scheme(1), a Koc of 6.4(2), indicates that fluoroacetamide is expected to have very high mobility in soil(SRC). Volatilization of fluoroacetamide from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.2X10-8 atm-cu m/mole(SRC), using a fragment constant estimation method(3). The potential for volatilization of fluoroacetamide from dry soil surfaces may exist (SRC) based upon an estimated vapor pressure of 0.99 mm Hg(SRC), determined from a fragment constant method(4). The persistence of fluoroacetamide was studied in garden soil by determining its toxicity to aphids(5); at a concn of 50 ppm, toxicity had ceased after 11 weeks of incubation; at a conc of 10 ppm, toxicity lasted only 3 weeks; in a control soil that had been steam sterilized, toxicity was still evident at both concns after 17 weeks suggesting that the degradation was microbial in nature(5).

AQUATIC FATE: Based on a classification scheme(1), a Koc of 6.4(2), indicates that fluoroacetamide is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 2.2X10-8 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). The neutral hydrolysis rate constant for fluoroacetamide at 25 °C was experimentally determined to be 3.3X10-5/hr which corresponds to an aqueous hydrolysis half-life of 2.4 yr at pH 7(8). This indicates that hydrolysis is slow(SRC). It has been suggested that fluoroacetamide should be degradable by biological sewage treatment provided suitable acclimatization can be achieved(9).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), fluoroacetamide, which has an estimated vapor pressure of 0.99 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere(SRC). Vapor-phase fluoroacetamide is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC). The half-life for this reaction in air is estimated to be 7.8 days(SRC), calculated from its rate constant of 2.1X10-12 cu cm/molecule-sec at 25 °C(SRC) determined using a structure estimation method(3).

The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

Inhalation (L1160) ; oral (L1160) ; dermal (L1160) ; eye contact (L1160).

Fluoroacetate produces its toxin action by inhibiting the citric acid cycle. The fluorine substituted acetate becomes incorporated, as a normal acetate, into fluoroacetyl coenzyme A, which condenses with oxaloacetate to form fluorocitrate. Fluorocitrate inhibits the enzyme aconitase and thereby inhibits the conversion of citrate to isocitrate. As a result there is an accumulation of large quantities of citrate in the tissue, and the cycle is blocked. The heart and CNS are the most critical tissues involved in poisoning by general inhibition of oxydative energy metabolism (A640).

Convulsions. Nausea. Vomiting.

MAY BE ABSORBED!

Abdominal pain. Nausea. Vomiting. Pupillary constriction. Muscle cramps. Excessive salivation.

Nausea, vomiting, excessive salivation, abdominal pain, numbness, a tingling sensation, and apprehension are seen initially, and may last for up to 6 hours. Numbness and tingling of the face, excessive salivation, blurred vision, peripheral paresthesias, convulsions, and coma followed inhalation and dermal contact with fluoroacetate (T36).

This substance may be hazardous to the environment. Special attention should be given to birds. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.

At about 1130 hr, an 18-month old girl removed a 120 ml bottle of 1% fluoroacetamide form a low drawer in the family kitchen & drank some of the contents. On the advice of a pharmacist, the child was given olive oil, the white of an egg, & milk at about noon & was made slightly sick. The child remained lively & played in the garden until her usual bedtime, 1830 hr. At about 2330 hr that evening the child vomited but was put back to bed when she appeared all right. Apparently the child was not checked until 1030 hr next morning, when she was found in a semiconscious state. On a physician's orders, she was taken to hospital, but convulsions occurred on the way & the patient arrived about 1130 hr in a shocked state. The child was given about 10 ml acetamide in water once, 3.7 ml of brandy in water each hour, & symptomatic treatment. She continued to have occasional convulsions & remained unconscious until she died almost 96 hr after ingesting the poison. Both the heart & kidney contained 6.3 mg of organic fluoride/g of dry tissue; the citrate content (108 ppm in heart & 23.9 in kidney) was not considered significantly high. From the evidence available, it was estimated that the baby had consumed about 300 mg of fluoroacetamide or 23 mg/kg.

A 2016 publication includes two case reports , one for fluoroacetamide (FAA) and one for TETS. Both patients were initially misdiagnosed and they died. The authors suggest that physicians should consider FAA and TETS poisoning when seeing patients with generalized seizures, especially for cases without a clear cause and diagnosis of disease.

Fluoroacetamide's production and former use as an insecticide and rodenticide(1) may have resulted in its direct release to the environment(SRC). Fluoroacetamide effluents from a manufacturing facility in Great Britain were reportedly responsible for the poisoning of farm animals(2).

FLUOROACETATE PRODUCES ITS TOXIC ACTION BY INHIBITING THE CITRIC ACID CYCLE. THE FLUORINE SUBSTITUTED ACETATE BECOMES INCORPORATED, AS A NORMAL ACETATE, INTO FLUOROACETYL COENZYME A, WHICH CONDENSES WITH OXALOACETATE TO FORM FLUOROCITRATE. FLUOROCITRATE INHIBITS THE ENZYME ACONITASE & THEREBY INHIBITS THE CONVERSION OF CITRATE TO ISOCITRATE. AS A RESULT THERE IS AN ACCUMULATION OF LARGE QUANTITIES OF CITRATE IN THE TISSUE, & THE CYCLE IS BLOCKED. ...

2,4-Dinitrofluorobenzene reacts with glutathione to form a stable product similar to that formed with the model glutathione-S-transferase substrate, 1-chloro-2,4-dinitrobenzene. ... Fluoroacetamide, like fluoroacetate, undergoes no discernable chemical defluorinantion. Its enzymatic defluorination is approx 10% of that observed for fluoroacetate and only 0.2% of the rate for 2,4-dinitrofluorobenzene. An antibody raised to the fluoroacetate specific dehalogenase precipitated both fluoroacetate ad fluoroacetamide defluorinating activity but had no effect on either 1-chloro-2,4-dinitrobenzene or 2,4-dinitrofluorobenzene activity. ... 2,4-Dinitrofluorobenzene is metabolized by the glutathione-S-transferase while fluoroacetamide is metabolized by the fluoroacetate specific dehalogenase.

Fluoroacetate administered ip to rats and mice is defluorinated to give fluoride ion evident in urine and kidney by (19)F NMR. The use of 2-(13)C-, 1,2-(13)C-, and 1,2-(14)C-fluoroacetate, ... reveals a complex mixture of urinary metabolites including an S-(carboxymethyl) conjugate complex in rats and mice and sulfoxidation products ... in rats. ... Bile, following treatment with 2-(13)C- fluoroacetate, shows the presence of S-(carboxymethyl)glutathione or a related conjugate and an O-conjugate of fluoracetate. Incubation of (13)C-fluoroacetate with rat and mouse liver cytosol involves formation of S-((13)C-carboxymethyl) glutathione and fluoride ion. Fluorocitrate is also /detected in/ fluoracetate incubations with mouse liver cytosol. Fluoroacetamide administered ip to rats and mice yields urinary fluoride ion formed via fluoroacetate which is liberated on hydrolysis by an organophosphate-sensitive amidase. (19)F NMR ... of other metabolites of fluoroacetamide are consistent with fluoroacetohydroxamic acid in the liver of mice and fluorocitrate in the urine of rats. Fluoroethanol gives rinary fluoroacetate and fluoride ion in rats and mice and is converted to fluoroacetaldehyde by mouse and rat liver microsomes. (-)- and (+)-erythro- fluorocitrates administered ip to rats yield mostly the parent compounds in urine at 6 hr with increasing amounts of fluoride ion thereafter. ... Rat and mouse liver cytosols defluorinate (-)-erythro-fluorocitrate. Metabolic defluorination and pig heart aconitase also defluorinates (-)-erythro- fluorocitrate. Metabolic defluorination of fluoracetate and its progenitors, fluoroacetamide and fluoroethanol, is therefore attributable to both conjucation of fluoracetate with glutathione and conversion to (-)-erythro-fluorocitrate, which is both an inhibitor of and a substrate for aconitase. ... Urine of rats and mice poisoned with fluoroacetate or (-)-erythro-fluorocitrate show elevated citrate and glucose and diminished urea consistent with disruptions in the tricarboxylic acid cycle and ammonia metabolism.

Fluoroacetamide is metabolized by the fluoroacetate specific dehalogenase (A323).
