Section 6. Accidental Release Measures

ANY HANDLING OF FLUORINATED ESTERS /INCL ETHYL FLUOROACETATE/...SHOULD BE DONE ONLY AFTER...PREPN FOR ALL POSSIBLE MEANS OF PREVENTING INTAKE INTO THE BODY.

Section 8. Exposure Controls / Personal Protection

8 hr Time Weighted Avg (TWA): 2.5 mg/cu m. /Fluorides, as F/

Excursion Limit Recommendation: Excursions in worker exposure levels may exceed 3 times the TLV-TWA for no more than a total of 30 minutes during a work day, and under no circumstances should they exceed 5 times the TLV-TWA, provided that the TLV-TWA is not exceeded. /Fluorides, as F/

A4; Not classifiable as a human carcinogen. /Fluorides, as F/

Biological Exposure Index (BEI): Determinant: fluorides in urine; Sampling Time: prior to shift; BEI: 3 mg/g creatinine. Determinant: fluorides in urine; Sampling Time: end of shift; BEI: 10 mg/g creatinine. The determinant may be present in biological specimens collected from subjects who have not been occupationally exposed, at a concentration which could affect interpretation of the result. Such background concentrations are incorporated in the BEI value. The determinant is nonspecific, since it is also observed after exposure to other chemicals. /Fluorides/

Section 11. Toxicological Information

A4; Not classifiable as a human carcinogen. /Fluorides, as F/

Neurotoxin - Other CNS neurotoxin

Occupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.

Lacrimator (Lachrymator) - A substance that irritates the eyes and induces the flow of tears.

...MAJOR TOXIC EFFECTS OF FLUOROACETATES IN MAN INVOLVE CNS & CARDIOVASCULAR SYSTEM. SEVERE EPILEPTIFORM CONVULSIONS ALTERNATE WITH COMA & DEPRESSION; DEATH MAY RESULT FROM ASPHYXIA DURING CONVULSION OR FROM RESP FAILURE. /FLUOROACETATES/

MOST PROMINENT FEATURES /OF FLUOROACETATE TOXICITY/...ARE CARDIAC IRREGULARITIES...VENTRICULAR FIBRILLATION & SUDDEN CARDIAC ARREST...USUALLY PRECEDED BY...LATENT PERIOD OF UP TO 6 HR CHARACTERIZED BY NAUSEA, VOMITING, EXCESSIVE SALIVATION, NUMBNESS...EPIGASTRIC PAIN & MENTAL APPREHENSION... /FLUOROACETATES/

...OTHER SIGNS & SYMPTOMS WHICH MAY DEVELOP SUBSEQUENTLY INCL MUSCULAR TWITCHING, LOW BLOOD PRESSURE & BLURRED VISION. /FLUOROACETATES/

...LITERATURE GIVES LITTLE INFORMATION ON IRRITANT PROPERTIES, IT APPEARS... ETHYL FLUOROACETATE...LACK/S/ INTENSE LOCAL EFFECTS ON EYE OF BROMO- & IODOACETATE ESTERS.

SIMPLE DERIV OF FLUOROACETIC ACID ARE GENERALLY HIGHLY TOXIC TO WIDE VARIETY OF VERTEBRATES & INVERTEBRATES. MODE OF ACTION INVOLVES IN VIVO CONVERSION OF FLUOROACETATE TO FLUOROCITRIC ACID SO THAT FLUOROACETIC ACID ESTERS...& OTHER SIMPLE COMPD...HYDROLYZED OR OXIDIZED IN VIVO TO FLUOROACETATE ARE ALSO HIGHLY TOXIC.

ETHYL FLUORORACETATE, HAS LD50 OF 6-10 MG/KG IN MICE, VERY SIMILAR TO FLUOROACETIC ACID. ...2-FLUOROETHYL ACETATE...IS ONLY SLIGHTLY LESS TOXIC, HAVING LD50'S OF 18 MG/KG (THESE ACTIVE FLUORO COMPD HAVE ALMOST IDENTICAL LD50'S BY ANY ROUTE OR ADMIN).
