MSHA recognition for Nett particulate filters

摘要

Nett Technologies Inc. received authoritative recognition by the U.S. Mine Safety and Health Administration (MSHA) for its diesel particulate filter (DPF) technology. This technology is pivotal in assisting retrofit compliance with the newly adopted MSHA rules regarding diesel particulate matter (DPM) emissions in underground mines. It is the first legislation to control miners' exposure to diesel particulate in the U.S. mines.The coal mine rule prohibits heavy duty diesel equipment to emit levels exceeding 2.5 grams per hour of DPM with a phase-in schedule beginning May 21, 2001. The metalonmetal (i.e. non-coal) mine rule establishes stringent DPM exposure limits effective July 19, 2001. Thousands of diesel engines in underground mines will be retrofitted with diesel particulate filters to comply with these regulations.
