2、.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice covers procedures for safely sampling andhandling 4,4-isopropylidinediphenol,commercially known asbisphenol A(BPA),in var
3、ious solid forms,and as a liquid atelevated temperatures in a manner which represents andpreserves product quality.1.2 Any person sampling or handling this product shouldhave consulted a safety Data Sheet(SDS)for specific first aidinstructions and information on the proper equipment to haveavailable
4、 for use in the event of personal contact or exposure.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibil
5、ity of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For specific hazardstatements,see Sections 3,4,5,6,7 and 8 and an appropriateSDS.2.Referenced Documents2.1 OSHA Regulations:29 CFR Labor,para

7、tion withan existing health and safety program and consultation with anappropriate SDS.The information provided herein cannot beused as a substitute for expert safety and medical advice asprovided in an appropriate SDS,but rather as a supplement tosuch advice.4.Description of Product(See Table 1)4.1
8、 Bisphenol A(BPA)is not classified as a hazardouschemical by the Department of Transportation,and is,therefore,not subject to DOT regulations governing the trans-portation of hazardous articles.Bisphenol A is normallytransported in several types of containers including cloth andpaper bags,bulk truck
9、s,and covered hopper cars.(See Table1.)4.2 While bisphenol A(BPA)is dangerous when handledimproperly,particularly at elevated temperatures,its unloadingneed not be hazardous provided the hazards are recognized andhandling instructions are rigidly observed as detailed here andin an appropriate SDS.5.
10、Hazards5.1 HealthConsult current OSHA regulations and suppli-ers Safety Data Sheet for all materials used in this practice.5.1.1 Aside from the risk of thermal burns in handling BPAwhen molten,and a possibility of dermatitis from impurities,particularly in crude grades,industrial use does not presen
11、t asignificant health hazard.However,ordinary precautions mustbe observed to protect personnel from contact with moltenBPA or excessive exposure to dusts or high concentrations ofvapor.5.1.2 Precautions must be observed to protect personnelfrom excessive inhalation of vapors and dust.5.2 Fire:5.2.1
12、BPA in both the solid and liquid form is combustibleand introduces a potential fire hazard when it is stored,handled,or used.5.2.2 BPA vapors or dust can form explosive mixtures withair.5.2.3 Dry chemicals,carbon dioxide,foam,and water canall be used in fighting fires involving BPA.1This practice is
