About This Course

Confined spaces in underground mines add serious risk to an already hazardous environment. This online course prepares underground personnel to recognize, assess, and control confined space hazards. Learners review confined space types (permit-required and non-permit), roles and responsibilities, permit elements, and more.

Designed for operators, supervisors, safety personnel, and all individuals who work at underground mines, the content references 30 CFR Part 48 for underground mining, related MSHA provisions in 30 CFR Parts 56 and 57, and applicable OSHA confined space standards (29 CFR 1910). It can be used within a company’s MSHA-approved training plan. Mine operators remain responsible for any required site-specific hazard training and for recording training on MSHA Form 5000-23 as outlined in 30 CFR §48.23.

If you need confined space training for surface mining operations, please visit our MSHA Part 46 Confined Spaces course.

This course is offered in partnership with Compliance Training Online™, a division of 360training™ company.

What Other MSHA Courses Do Underground Miners Need Besides Confined Space Training?

Confined space hazards are only one part of underground mining safety. 360training offers several other MSHA Underground Mining courses that build a complete understanding of workplace risks. These include:

Together, these courses help miners strengthen hazard awareness, improve response readiness, and reinforce confined space hazard awareness.

How Does the MSHA Underground Mining Confined Spaces Course Prepare Me?

This course prepares miners to safely recognize, evaluate, and control confined space hazards commonly found in underground mining. You’ll learn how to identify permit-required and non-permit-required confined spaces, understand the roles and responsibilities of entrants, attendants, supervisors, and contractors, and follow the elements of a confined space permit from planning through pre-entry preparation.

Training also builds awareness of atmospheric and physical hazards including oxygen deficiency, flammable or toxic gases, engulfment, electrical risks, and temperature extremes.

Should Surface Miners Take the MSHA Underground Mining Confined Spaces Course?

No. This course is designed for underground miners who fall under MSHA Part 48 regulations. Surface miners have different training requirements under MSHA Part 46, which addresses confined space hazards specific to surface mine environments. If you work in surface mining, take our MSHA Part 46 Surface Mining Confined Spaces course to ensure you receive the correct training for your worksite.
