Application
Many categories of contract labor may be present at a jobsite; such
workers may actually operate the facility or do only a particular
aspect of a job because they have specialized knowledge or skill.
Others work only for short periods when there is need for increased
staff quickly, such as in turnaround operations. PSM includes special
provisions for contractors and their employees to emphasize the
importance of everyone taking care that they do nothing to endanger
those working nearby who may work for another employer.
PSM, therefore, applies to contractors performing maintenance or
repair, turnaround, major renovation, or specialty work on or adjacent
to a covered process. It does not apply, however, to contractors
providing incidental services that do not influence process safety,
such as janitorial, food and drink, laundry, delivery, or other supply
services.
