## Abstract

The Mine Safety and Health Administration (MSHA) is correcting an amendatory instruction in a final rule that was published in the Federal Register on April 18, 2024. The document amended the Agency's existing standards to better protect miners against occupational exposure to respirable crystalline silica, a significant health hazard, and to improve respiratory protection for miners from exposure to airborne contaminants.
