This 1999 image showed a worker, using a power sander equipped with a high efficiency particulate air filter exhaust system that collected paint particulates, as he removed paint from a door, during an exterior residential renovation method, where lead-based paint was present. This was found to be a low-exposure method present. Due to the use of a HEPA vacuum filter, this was classified as use of a low-exposure renovation method. The University of California, Berkeley, and local members of the Painting and Decorating Contractors of America conducted the demonstration. These organizations requested that industrial hygienists at the National Institute for Occupational Safety and Health (NIOSH), conduct a health hazard evaluation in order to assess workers’ lead exposures, inherent in performing various tasks. Note that this worker was appropriately attired so as to avoid skin, or inhalation exposure to possibly dangerous airborne particulates.
