Standard Practice for Asbestos Exposure Assessments for Repetitive Maintenance and Installation Tasks
SIGNIFICANCE AND USE
4.1 Work practices, engineering controls, personal protective equipment and other precautions to minimize exposure to airborne asbestos fibers have been extensively documented in regulations, training manuals and other publications. The work described in these publications ranges from large-scale abatement projects to minor disturbances and clean-up. Practices E1368 and E2394 address these issues within the context of their subject matter.
4.2 This practice applies to specific types of asbestos work where the same task is performed by various persons without substantial deviation from a documented procedure and with material containing the same type and similar content of asbestos fiber. The exposure from such operations can be expected to remain fairly consistent as long as these parameters do not vary substantially and the workers have received the required training to perform the task.
4.3 Because of the variability in field conditions under which large-scale work such as asbestos abatement is performed, the opportunity to collect sufficient personal air samples under conditions similar enough to establish statistical confidence can be questioned. For this reason, this practice does not address the collection of such samples and their use for determining exposure data to apply on other projects. Users with such requirements are referred to the applicable regulations for guidance.
4.4 There are many tasks, however, that are of short duration and amenable to testing under controlled conditions for assessing worker exposure. These tasks are performed by equipment installers and other tradesmen in the course of their ordinary duties in what this practice refers to as the current job. The following list of potential tasks where ACMs can be disturbed is by no means inclusive and the feasibility of conducting an Exposure Assessment is the responsibility of the user:

SCOPE
1.1 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.
1.2 This practice describes the facilities and equipment for performing the tasks under controlled conditions for the express purpose of collecting personal air samples to determine worker exposure. The tasks are performed on actual asbestos-containing materials during Exposure Assessment tests and precautions are taken for personal protection and avoiding contamination of adjacent spaces.
1.3 This practice describes the air sample collection procedures, the analytical methods for the air samples, and the calculation of worker exposure including the use of statistical confidence limits. This practice differentiates between the test to obtain exposure data and the current job to which the data are applied, and describes the duties of the individuals who conduct these separate activities.
1.4 The results are applied to the current job as defined herein for determining worker protection such as respiratory protection or for other purposes as determined by the competent person responsible for the current job. The results of the tests shall not be applied to current jobs that are expected to differ substantially from the test conditions in work practices, material properties or other factors that might affect the concentration of airborne asbestos fibers.
1.5 This practice is not intended to be used for asbestos abatement work for which the objective is the removal of asbestos-containing materials. It is designed to assess exposures for short-term repetitive tasks. Compliance with regulatory requirements as to the purpose of the work and limits on the quantity of asbestos-containing materials disturbed is the responsibility of the user.
