MSHA Guarding Machinery at Metal & Nonmetal Mines

As a reminder, providing proper guarding of machinery is required per MSHA regulations.  This guide provides compliance information to help the metal and nonmetal mining industry meet current requirements of the Mine Safety and Health Administration’s (MSHA’s) guarding standards addressing machinery.   This document is also intended to enhance awareness of guarding compliance for miners, mine operators, miners’ representatives, independent contractors, equipment manufacturers, and MSHA’s Metal and Nonmetal enforcement personnel with compliance issues related to guarding machinery.  This guide should be used to supplement existing guarding guidance contained in “MSHA’s Guide to Equipment Guarding” published in 2004, and in MSHA’s existing Program Policy Manual.
