Description:
This paper discusses the strategy, accomplishments and current direction of a highly experienced engineering-control effort incorporating diversified monitoring and advanced analytical instrumentation directed primarily towards eliminating airborne asbestos emissions in buildings. he paper draws from ten years of field monitoring, release episodes and abatement failures and successes. he advantages as well as certain disadvantages of using the Transmission Electron Microscopy (TEM) for clearance after an abatement action is addressed as is the effectiveness and usefulness of visual inspection to reduce both the cost of TEM analysis and the effectiveness of the removal process. n-site performance evaluations of "negative-air" High Efficiency Particulate Air (HEPA) cleaners required in abatement operations have provided interesting findings, as has the long-term effectiveness (of non-contaminated air) for various ACM (asbestos-containing materials) removals. peration and maintenance practices are critiqued based on experiments involving EPA vacuuming including the bag-changing practices, and stripping (wax removal) and buffing practices for vinyl asbestos tile (VAT).
