ASTM D4297-15(R2020) pdf free download.Standard Practice for Sampling and Handling Bisphenol A (4,4′ -Isopropylidinediphenol)
1. Scope
1.1 This practice covers procedures for safely sampling and handling 4,4′-isopropylidinediphenol, commercially known as bisphenol A (BPA), in various solid forms, and as a liquid at elevated temperatures in a manner which represents and preserves product quality. 1.2 Any person sampling or handling this product should have consulted a safety Data Sheet (SDS) for specific first aid instructions and information on the proper equipment to have available for use in the event of personal contact or exposure. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability of regulatory limitations prior to use. For specific hazard statements, see Sections 3, 4, 5, 6, 7 and 8 and an appropriate SDS. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Significance and Use
3.1 This practice is issued to provide information useful in establishing sampling and handling procedures. It is expected that this information will only be utilized in conjunction with an existing health and safety program and consultation with an appropriate SDS. The information provided herein cannot be used as a substitute for expert safety and medical advice as provided in an appropriate SDS, but rather as a supplement to such advice.
4. Description of Product (See Table 1)
4.1 Bisphenol A (BPA) is not classified as a hazardous chemical by the Department of Transportation, and is, therefore, not subject to DOT regulations governing the trans- portation of hazardous articles. Bisphenol A is normally transported in several types of containers including cloth and paper bags, bulk trucks, and covered hopper cars. (See Table 1.) 4.2 While bisphenol A (BPA) is dangerous when handled improperly, particularly at elevated temperatures, its unloading need not be hazardous provided the hazards are recognized and handling instructions are rigidly observed as detailed here and in an appropriate SDS.
5. Hazards
5.1 Health—Consult current OSHA regulations and suppli- er’s Safety Data Sheet for all materials used in this practice. 5.1.1 Aside from the risk of thermal burns in handling BPA when molten, and a possibility of dermatitis from impurities, particularly in crude grades, industrial use does not present a significant health hazard. However, ordinary precautions must be observed to protect personnel from contact with molten BPA or excessive exposure to dusts or high concentrations of vapor. 5.1.2 Precautions must be observed to protect personnel from excessive inhalation of vapors and dust. 5.2 Fire: 5.2.1 BPA in both the solid and liquid form is combustible and introduces a potential fire hazard when it is stored, handled, or used. 5.2.2 BPA vapors or dust can form explosive mixtures with air.
8. Safety Precautions
8.1 Exercise care to prevent spills and leaks. If they do occur, only properly protected personnel should remain in the contaminated area in accordance with the instructions in an appropriate SDS. All spill-related activities should comply with applicable EPA, OSHA, and local regulations and laws. 8.2 Because of fire and dust explosion hazards, do not permit open flames in the vicinity of tank carriers, other shipping containers, or storage tanks. Provide all electrical fixtures with vapor-proof globes and explosion-proof safety devices. Ground tank carriers by an approved method. Prohibit smoking. All pneumatic conveying should be done with nitrogen or other inert gas. 8.3 Any person sampling or handling these products should have consulted an appropriate SDS for specific first aid instructions and equipment to have available for use in the event of personal contact or exposure. 8.4 Conduct sampling and handling operations in accor- dance with the instructions in an appropriate SDS.
