MSHA training, explained.
What it is, who needs it, when it's required, and why it matters.
What is MSHA?
The Mine Safety and Health Administration (MSHA) is the federal agency that regulates safety in U.S. mines. They write the rules, inspect the sites, and require that every miner — and every contractor on a mine site — receive specific training before they start working and every year after.
Who needs MSHA training?
- New miners (before they start)
- Experienced miners (every 12 months for refresher)
- Newly hired experienced miners (when they switch operations)
- Contractors, vendors, and anyone visiting a mine site
- Supervisors and mine operators
Part 46 vs. Part 48 — which one do I need?
| MSHA Part 46 | MSHA Part 48 |
|---|---|
| Surface mines — sand, gravel, surface stone, clay, limestone, colloidal phosphate, shell dredging | All underground mines, surface coal mines, certain surface metal/nonmetal |
| 24 hours new miner training | 40 hours new miner training (underground) |
| Online OR in-person allowed | Must be in-person with MSHA-approved instructor |
| 8 hours annual refresher | 8 hours annual refresher |
How often is MSHA refresher training required?
Every miner must complete at least 8 hours of refresher training every 12 months. The clock starts at the end of the previous training. Miss the deadline and the miner must be pulled from work until they're current.
Is MSHA stricter than OSHA?
Yes, in several ways. MSHA's standards are more detailed and specific, penalties for similar offenses tend to be higher, inspections happen more frequently, and twelve specific types of accidents must be reported within 15 minutes (vs. OSHA's 8-hour or 24-hour windows).
Can I take MSHA training online?
Part 46 — yes, online is acceptable. Part 48 — no, federal law requires Part 48 training to be delivered in person by an MSHA-approved instructor.
Why choose in-person training over online?
- Real discussion and Q&A with a working miner
- Site-specific stories that actually stick
- Hands-on demonstration
- Engagement that retains — boring online modules don't save lives
- A trainer who can answer your specific questions on the spot
How do I prove I've been trained?
MSHA Form 5000-23 — the official Certificate of Training. Stone MSHA Training provides this on completion of every course. Keep a copy. Your employer is required to keep a copy on file for the duration of employment plus 60 days.
What happens if I'm not current?
Federal law requires that you cannot legally work as a miner without current MSHA training. Mines that allow untrained miners to work face significant fines, citations, and shutdown risk. It's not worth it. Stay current.
