(Practice)Standard Practice for Sampling and Handling Naphthalene, Maleic Anhydride, and Phthalic Anhydride
Standard Practice for Sampling and Handling Naphthalene, Maleic Anhydride, and Phthalic Anhydride
SIGNIFICANCE AND USE
3.1 This practice is issued to provide information useful in establishing sampling procedures. It is expected that this information will only be utilized in conjunction with an existing health and safety program and consultation with the appropriate SDS. The information provided herein cannot be used as a substitute for expert safety and medical advice, but rather as a supplement to such advice.
SCOPE
1.1 This practice covers procedures for sampling and handling naphthalene, maleic anhydride, and phthalic anhydride in various solid forms, and as liquids at elevated temperatures in a safe manner that represents and preserves quality.
1.2 Any person sampling or handling these products should consult the applicable 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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Sections 3, 4, 5, 6, and 7 and an appropriate SDS.

classified as hazardous by the Department of Transportation and are subject to DOT regulations. Maleic anhydride has the
classification corrosive material, and naphthalene has the classification flammable solid.
