Expert 2762 was responsible for selecting analytical methodology, setting up and validating all
analytical procedures, supervising the performance of company chemists and field operations, and quality
assurance of all work performed for.  For approximately 18 years, company routinely inspected buildings and
other facilities, analyzed bulk, air filter and other environmental types of samples for asbestos content,
designed and monitored asbestos abatement projects while usually working for the building owner, and
performed in-house research and development of asbestos surface sampling and testing procedures, as well
as creation of an asbestos product identification database, utilizing authenticated samples of various asbestos
products.  Consulted with, and/or testified for many governmental, educational, industrial and individual clients
over the period of approximately 1979 to the present on a broad range of aspects involving asbestos
exposure, best industrial hygiene practices, asbestos inspection and management planning, asbestos
abatement specification writing, conducting project supervision/worker training, asbestos control technology,
negative air glove bag / glove box technology, surface contamination monitoring practices, surface cleaning
practices, abatement project design and performance practices, OSHA regulations and
compliance/interpretation, EPA regulations and compliance/interpretation, laboratory analytical methodology,
and asbestos technology/regulatory state-of-the-art. Performed retrospective asbestos contamination surveys
and using dust exposure risk-estimating models for toxic/carcinogenic particulates which were developed in
house, calculated the worse-case asbestos exposures to certain occupants.  These models have successfully
been utilized in casework involving asbestos fiber exposures from generalized building contamination and
have been accepted in at least one court case to date.

During the period of approximately 1970 to the present, Expert 2762 has also performed research on asbestos-related issues and testified as a expert in asbestos product liability and worker/occupant exposure cases.  He has also performed original research and published this work in dealing with the development of methods and models to calculate the release and movement of hazardous dust particulates in building environments for exposure risk assessment.  He has been a paid peer reviewer and consultant to the U.S. Environmental Protection Agency and to the National Institutes of Occupational Safety and Health in those subject areas as well as in the development of new control methods for safe dust control during abatement of hazardous construction materials.  He has also been a paid consultant/trainer to Virginia Occupational Safety and Health Administration to train their compliance officers and in-house training personnel in long-term, low-level asbestos hazard and exposure assessment procedures. Expert 115 created, presented and sponsored the first asbestos training seminar courses in the United States in 1980 after seeing a need for such information.  They were well attended by various governmental officials, including representatives of the EPA and OSHA and some federal legislators.  Subsequently, the EPA adopted the course design and information content as the primary requirements when they promulgated asbestos training requirement regulations several years later.

During this period of operations, Expert 2762 performed a number of comprehensive industrial hygiene surveys of military bases, industrial and manufacturing plants in which asbestos exposure was detected and monitored.  Various forms of asbestos products were located, sampled, analyzed and evaluated relative to OSHA and other government regulations and air and surface contamination from free asbestos fiber were measured to determine the levels of maximum exposure.
Expert 2762 has been an EPA-certified asbestos inspector, management planner, project designer, and contractor/supervisor for many years after AHERA regulations were enacted and licensed as such in the state of Virginia.  He trained many of the state of Virginia and EPA regulatory and research personnel prior to enactment of their respective asbestos regulations.  He has conducted numerous asbestos hazard surveys (both residential and workplace) from approximately 1980 to the present.  He is also American Board of Industrial Hygiene-certified as an industrial hygienist in comprehensive practice, including toxicology practice.  In that capacity as noted above, he has performed numerous industrial and environmental evaluations of overexposure to asbestos and other hazardous substances in the workplace.

Among thousands of clients involving asbestos related issues include the U.S. Navy (first asbestos consultant to this military service, helping in development of asbestos detection and abatement program), the U.S. General Services Administration (asbestos contamination and abatement in government buildings), the Veterans Administration, the state Attorneys General of Virginia and Massachusetts (asbestos hazard assessment and expert witness services in cost recovery litigation), the school districts of Washington, DC, Philadelphia, PA and Norfolk, VA, along with hundreds of other schools and school districts across the U.S., various city and county governments (Norfolk, VA, Portsmouth, VA, Virginia Beach, VA, Arlington, VA, Philadelphia, PA, Washington, DC, Chesapeake Bay Bridge Tunnel Authority (design and monitored the longest asbestos abatement project to date – 21 miles of asbestos removal work), numerous high rise office type building inspections and abatement project design/monitoring services,  Lloyds of London (asbestos-contaminated cargo and decontamination procedures), IBM,  and many law firms involved in asbestos litigation. Expert 2762 has rendered a considerable number of affidavits, depositions and testimony regarding the “inherent danger’ of asbestos products, the ease of exposure to free asbestos fibers in environments and buildings containing these products, and the ease of transport (“asbestos fiber drift”) nature of asbestos in buildings and their associated locales.  His asbestos fiber drift testimony has met the Daubert criteria for admissibility in Ohio state court.
Expert 2762 has published numerous papers and articles on many aspects of asbestos technology and the related science, control technology and management issues.  These publications are available upon request, as is an extensive case list file.
