FIFRA 요건

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Tetrasodium pyrophosphate is found on List D. Case No: 4053Pesticide type: fungicide, herbicide, antimicrobialCase Status: None of the active ingredients in the case are being supported for reregistration by their registrants. All are unsupported, or some are unsupported and some are cancelled. Cases described as "unsupported" generally are being processed for cancellation.Active ingredient (AI): Tetrasodium pyrophosphateAI Status: The active ingredient is no longer contained in any registered products ... "cancelled."Residues of tetrasodium pyrophosphate are exempted from the requirement of a tolerance when used as a anticaking agent or conditioning agent in accordance with good agricultural practices as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest.

응급 조치	Fresh air, rest. Refer for medical attention.Remove contaminated clothes. Rinse and then wash skin with water and soap.First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.Rinse mouth. Refer for medical attention .

처리 방법	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.

누출 처리	Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.

Preventive Measures	The worker should immediately wash the skin when it becomes contaminated.Work clothing that becomes wet or significantly contaminated should be removed and replaced.Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises.

Allowable Tolerances	Residues of tetrasodium pyrophosphate are exempted from the requirement of a tolerance when used as a anticaking agent or conditioning agent in accordance with good agricultural practices as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest.

It is used in textile dyeingscouring of woolbufferfood additivedetergent builderwater softener and dispersant. HUMAN EXPOSURE AND TOXICITY: Alkaline and irritating. Nausea, vomiting and diarrhea are probable after ingestion. Medical reports of acute exposures show mild to moderate dermal and ocular responses. ANIMAL STUDIES: Tetrasodium pyrophosphate when added to the diets of rats in high concentrations it caused kidney damage. This chemical caused teratogenic effects in chicken embryos. Acute studies show that direct contact causes severe irritation and corneal injury in the rabbit eye and that it may be irritating to skin. This chemical can be considered moderately toxic on ingestion, inducing metabolic acidosis, and hypocalcemia.
