We conduct annual Industrial Hygiene Surveys and continue to monitor them on a more frequent, quarterly basis. The most recent survey tested for air quality, including total particulates, respirable dust, silica, and metal. All results were well under the best practice threshold limit values set by the American Conference of Governmental Industrial Hygienists (ACGIH), an independent standards-setting body, and significantly under OSHA-developed threshold limit values. We recently installed a new internal baghouse, an industrial air filter system, to draw off point source potential dust generation areas. We plan to conduct these surveys at our Thomaston Circularity Center.
