Standard Practice for Sampling and Handling Bisphenol A (4,4!-Isopropylidinediphenol)
SIGNIFICANCE AND USE
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.

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 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.
