This practice is intended for use by employers in developing their own specific operation standards for solvent vapor degreasing operations.

Certain vapor degreasing operations are subject to the requirements of the National Emission Standards for Halogenated Solvent Cleaning (Halogenated Solvent Cleaner NESHAP) as found in 40 CFR Part 63, Subpart T. The determination of the applicability of these, or any additional requirements is the responsibility of the user.

This practice is not intended to address all of the requirements contained in the Halogenated Solvent Cleaner NESHAP. Development and implementation of training programs, recordkeeping, and other additional requirements of the NESHAP are the responsibility of the user.

1.1 This practice recommends work practices for conventional vapor degreasing operations utilizing any solvent or solvent blend that has been categorized as nonflammable.

1.2 This practice is not intended for use in vapor degreasing operations utilizing flammable (low flash point) solvents or in vapor degreasing operations utilizing enclosed (sealed, airtight) equipment. For these non-applicable operations, users should consult the solvent or equipment supplier for additional information.

1.3 The values given in inch-pound units are to be regarded as the standard. The values stated in parentheses are for information only.

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.
