1. Scope
This Practice establishes procedures for assessing the exposure of workers to airborne fibers who perform repetitive tasks of short duration where small quantities of asbestos-containing materials must be disturbed in order to perform maintenance and installation activities.
Work is routinely performed during maintenance and installation of equipment where small amounts of asbestos-containing materials are disturbed for short periods of time. This is not asbestos abatement for the purpose of removing asbestos; the disturbance is incidental but necessary to performing the maintenance or installation task. The OSHA Construction Industry regulations for assessing worker exposure during such tasks are interpreted in different ways by different people, and there is a need to standardize the methodology for conducting tests under controlled conditions, analyzing the air sample data, determining statistical confidence limits for comparison with the OSHA Permissible Exposure Limits and other criteria, and providing guidance to the employers competent person for determining respiratory protection requirements for work covered by Exposure Assessments.
