Air sampling and analysis is critical in determining exposure to airborne asbestos fibers for both the worker and the unprotected public in the area surrounding an abatement project. Due to the microscopic size of asbestos fibers, air sampling is the only definitive way of determining these exposures as well as to determine if an abatement site can be released for re-occupation. Collection of reliable data requires a thorough knowledge of the techniques and equipment used in air sampling. Area air samples are collected in pre-selected locations using either low volume battery operated or high volume electric sampling pumps.
New York State Code Rule 56 specifies four distinct categories of asbestos abatement project area air monitoring:
- Daily (work-in-progress)
- Final Clearance
OSHA requires that the analytical laboratory successfully participate in a national quality assurance program. For work performed in New York State, the analytical laboratory selected must be accredited/certified by the American Industrial Hygiene Association (AIHA) and the New York State Department of Health Environmental Laboratory Approval Program (NYSDOH ELAP).
