Meeting Details:
Description: Home and building owners, who have vermiculite attic insulation (VAI), may want to know whether the vermiculite contains Libby amphibole. The purpose of this day and a half workshop is for a panel of experts to meet and propose a method to determine whether Libby amphibole is present in a sample of VAI. The objective of the method is to be: accurate with respect to identifying Libby amphibole, affordable to the average homeowner, and adaptable to most current commercial fiber analysis laboratories. This method will not identify or measure other non-Libby amphibole components of the VAI and will not make any judgments on potential risk from Libby amphibole or disturbed/undisturbed VAI.
The “Cincinnati Method” addresses measuring Libby Amphibole in vermiculite attic insulation (VAI). The “Cincinnati Method” will most likely be the starting point to propose the new method, which is (a) accurate with respect to identifying Libby amphibole, (b) affordable to the average homeowner, and (c) adaptable to most current commercial fiber analysis laboratories, to determine whether Libby amphibole is present in a sample of VAI.
