A forest products concern retained me to audit the asbestos management program at one of their mills. A consultant had taken over 30,000 bulk samples of thermal system insulation since the mid-1990s and compiled the information in a database. Even with that amount of data, contractors were still encountering unidentified ACM fairly recently. My assignment was to analyze the database and recommend how its reliability could be improved and it could be used more efficiently. Over a four-month period that included a visit to the mill, I produced two reports that detailed quality control problems with the database, including mis-identification of samples and uncertainties in the identification of materials in multi-layer samples. I made recommendations for eliminating unnecessary information in the database and reorganizing the remainder as well as improving the way the information was displayed for the user. Suggestions were also made to improve the markings on pipes and tanks with which ACM was distinguished from non-ACM.
