National Occupational Exposure Survey (1981 - 1983)
Acute Toxicity: Exposure to thermal decomposition products can cause serious hydrogen fluoride burns and corrosion.
Fire Hazards: Thermal decomposition may produce an irritating mixture of smoke and highly toxic gases. Fluoride emissions may be significant. Fire fighters should wear full protective gear including self-contained breathing apparatus with full faceplate and full protective clothing.
Hazardous Products of Combustion: Toxic and irritating fumes and gases including hydrogen fluoride.

US EPA List of Inerts. This substance is on List 3.

Note: US EPA allows so-called "Inert" ingredients to be commonly mixed with the "active" pesticidal ingredient to create a formulated pesticide product. According to EPA, "The term `inert' is not intended to imply nontoxicity; the ingredient may or may not be chemically active." "Inert" ingredients include solvents, emulsifiers, spreaders, and other substances mixed into pesticide products to increase the effectiveness of the active ingredients, make the product easier to apply, or to allow several active ingredients to mix in one solution. Both US EPA and California Department of Pesticide Regulation require pesticide manufacturers to identify inert ingredients in their products but do not disclose this information to the general public because the pesticide industry considers product formulations trade secrets, protected by law and by the US EPA. The US EPA category of Inerts (as of September 2003):

List 1 - Of Toxicological Concern
List 2 - Potentially Toxic / High Priority for Testing
List 3 - Of Unknown Toxicity
List 4A - Generally Regarded as Safe
List 4B - EPA states it has Sufficient Information to Reasonably Conclude that the Current Use Pattern in Pesticide Products will not Adversely Affect Public Health or the Environment
List 4 (all)

Extractables from PVDF piping systems conveying high-purity waters

Authors: Meltzer TH

Author Address: Capitola Consulting Co., 1805 Crystal Dr., Unit 318, Arlington, VA 22202-4402, USA

Abstract: IPA COPYRIGHT: ASHP A study evaluating the nature of extractables leached by high-purity waters from polyvinylidene fluoride (PVDF) piping systems via a model consisting of a PVDF-lined pump and a PVDF tank through which 20 liters of high-purity water was circulated for 2 h at a rate of 5 ft/sec is described; anions, cations, and total organic carbon were measured against current standards for high-purity waters used in pharmaceutical operations. Results indicated that most of the substances were extracted only to levels approaching the limits of analytic detection.

Evaluation of Emission Control Options at Leeds Architectural Products.

Authors: Bolstad JN

Author Address: Engineering Science, Fairfax, VA.

Abstract: TD3: The U.S. Environmental Protection Agency's Control Technology Center evaluated feasible alternatives to control emissions of volatile organic compounds (VOC) from a specialty aluminum coating facility in CT. The facility desired to increase its use of high VOC content liquid polyvinylidene fluoride (PVF) Kynar(R) coatings. The report examines several options for emission control by incineration of spray booth and bake oven exhaust gases. The report also discusses the development of Kynar(R) powder coatings, other PVF powder coatings and triglycidyl isocyanurate (TGIC) polyester powder coatings with performance characteristics similar to liquid Kynar(R) coatings.
