Should I Take the MSHA Part 48 2-Hour or 8-Hour Refresher?

It depends on your training needs and level of experience. The 2-hour refresher is best for returning underground miners who need a quick review of safety topics or a reminder of recent compliance changes. The 8-hour refresher is required annually for most experienced underground miners to meet full MSHA Part 48 refresher requirements under 30 CFR 48.8 and 48.28.

If you’re unsure which version applies to your situation, start with your mine operator or safety manager. You can also learn more on the MSHA Part 48 8-Hour Underground Mining Refresher course page.

Do You Offer Other MSHA Refresher Courses for Underground Miners?

Yes. 360training offers several MSHA refresher options to meet different underground mining needs. In addition to this 2-hour course, we also provide a comprehensive MSHA Part 48 8-Hour Underground Mining Refresher. Each course supports compliance with MSHA Part 48 training requirements and can be used within your company’s approved training plan.

Is This MSHA Refresher Course Good for Surface Miners?

No. This course is specifically designed for underground miners covered under MSHA Part 48 Subpart A. Surface miners who work at underground mine sites must follow Subpart B training requirements instead. If you need refresher training for surface mining, see our MSHA Part 48 Subpart B Surface Mining Refresher or our Part 48 Subpart B 2-Hour Surface Mining Refresher course.
