The Occupational Safety and Health Administration (OSHA) has issued a final rule to curb lung cancer, silicosis, chronic obstructive pulmonary disease, and kidney disease in America's workers by limiting their exposure to respirable crystalline silica. This rule requires engineering controls to keep workers from breathing silica dust.
Dust extractor must provide the airflow recommended by the tool manufacturer, or greater, and have a filter with 99% or greater efficiency. DEWALT extractors ship with dual HEPA filters, which have an efficiency of 99.97%. They provide necessary airflow for drilling and hammering.
Operate and maintain tools in accordance with manufacturer's instructions to minimize concrete dust exposure. To minimize dust exposure, use recommended shroud or cowling, and dust extractor.
ACCESSORIES & SHROUDS
Use drill equipped with commercially available shroud or cowling with dust collection system. All DEWALT shrouds and dust collection systems are commercially available.
