The subject standard is a performance oriented standard and therefore, it would not be appropriate for OSHA to evaluate your set of specific procedures to determine if they apply to all workplaces covered by the PSM standard. The only requirements OSHA specifies in the subject standard is that the PHA update and revalidation be conducted at least every five years by a team which meets the requirements of 1910.119(e)(4).
Even though OSHA does not specify other requirements for this standard, 1910.119(e)(6), OSHA does require employers to insure that PHAs are current and accurately reflect covered processes. To determine if a PHA can be revalidated and updated, employers must make evaluations of existing PHAs using the specific requirements to be addressed in a PHA as defined in 29 CFR 1910.119(e)(3). After employers evaluate existing PHAs using the 29 CFR 1910.119(e)(3) criteria and have made updates when necessary, then employers may revalidate their respective PHAs as being
