I am familiar with MSHA (Mine Safety and Health Administration) regulations, particularly as they relate to underground mining operations. These regulations cover various aspects of safety, including diesel-powered equipment 1, 4, ventilation [1], fire prevention 2, 5, and emergency response [2].

For example, MSHA regulations are referenced in the context of diesel-powered equipment used in underground mines, requiring certification or compliance with specific standards 1, 4. Additionally, for mobile diesel-powered equipment used underground, compliance with MSHA provisions in 30 CFR 57.5067 is required [1].

Keep in mind that specific requirements can vary based on the type of mine and the operations conducted. Always consult the most up-to-date MSHA regulations and any relevant state or local regulations to ensure full compliance.
