The Asbestos Worker refresher training recertifies individuals to remove, encapsulate, enclose, repair, or disturb friable or non-friable asbestos, and to handle asbestos material in any manner which may result in the release of asbestos fiber on an asbestos abatement project. EPA certified asbestos classes have a one-year certification with a one-year grace period. If you fail to take the refresher class by the expiration date you cannot perform the AHERA job duties until you take a refresher class. If you go longer than one year past your expiration date without taking a refresher class, you are required to retake the initial certification class. If you did not take your last course from Pinnacle, please provide in advance a copy.
