ASTM D4297-05(2009)

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:D4297–99 Designation: D 4297 – 05 (Reapproved 2009)
Standard Practice for
Sampling and Handling Bisphenol A
(4,4* -Isopropylidinediphenol)
This standard is issued under the fixed designation D 4297; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1This practice covers procedures for safely sampling and handling 4,48-isopropylidinediphenol, commercially known as
bisphenol A, in various solid forms, and as a liquid at elevated temperatures in a manner which represents and preserves product
quality.
1.2Any person sampling or handling this product should have specific first aid instructions and equipment available for use in
the event of personal contact or exposure.
1.3This 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 appropriate safety and health practices and determine the applicability of regulatory
limitations prior to use. For specific hazard statements, see Sections 4-8 and 9Scope*
1.1 This practice covers procedures for safely sampling and handling 4,48-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 Material Safety Data Sheet (MSDS) 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 inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered 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 appropriate safety and health practices and determine the applicability of regulatory
limitations prior to use. For specific hazard statements, see Section 8.

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 MSDS. The information provided herein cannot be used as a substitute for expert safety and medical advice as
provided in an appropriate MSDS, 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 DOTregulations governing the transportation of hazardous articles. BisphenolAis normally transported in several types
of containers including cloth and paper bags, bulk trucks, and covered hopper cars. (See Table 1.)
This practice is under the jurisdiction of ASTM Committee D16 on Aromatic Hydrocarbons and Related Chemicals and is the direct responsibility of Subcommittee
D16.OJD16.08 on Handling and Sampling Aromatic and Cyclic Hydrocarbons.

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 MSDS.
5. Hazards
5.1 Health—ConsultcurrentOSHAregulationsandsupplier’sMaterialSafetyDataSheetsforallmaterialsusedinthispractice.
5.1.1 Aside from the risk of thermal burns in handling bisphenol A 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 bisphenol ABPA 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:
5.2.1Bisphenol A in both the solid and liquid form is combustible and introduces a potential fire hazard when it is stored,
handled, or used.
5.2.2Bisphenol A vapors or dust can form explosive mixtures with air.
5.2.3Dry chemicals, carbon dioxide, foam, and water can all be used in fighting fires involving bisphenol A.
5.3For chemical emergency (spill, leak, fire, exposure, or accident) call CHEMTREC, day or night at 1-800-424-9300. For
emergency calls outside the United States, call 703–527–3887. (Collect calls are accepted and all calls are recorded.)
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.
5.2.3 Dry chemicals, carbon dioxide, foam, and water can all be used in fighting fires involving BPA.
6. Protective Equipment
6.1EmployeeswhoworkwithbisphenolAshouldbewelltrainedandshouldmaintainsafeworkingconditions.Personshandling
molten bisphenol-A require eye, face, respiratory, body, skin, and hand protection. Handling solid bisphenol A requires hand and
body covering clothing to prevent excessive exposure to dust, safety glasses with side shields, and respiratory protection such as
a dust mask.
6.2Personal protective equipment is not an adequate substitute for good safe working conditions, proper ventilation, and
intelligent conduct. Correct usage of protective equipment requires education in its proper use.
6.1 Employees who work with BPA should be well trained and should maintain safe working conditions. They should be
required to read an appropriate MSDS for BPA in it’s entirety and consult appropriate, local, safety personnel if they have any
questions or concerns. Persons handling molten bisphenol-A need to exercise particular care.
7. First Aid
