New underground employees with no underground mining experience shall receive no less than how many hours of training?

• A. 8 Hours
• B. 16 Hours
• C. 24 Hours
• D. 40 Hours

Answer: (C)

New underground workers with no underground mining experience must complete a baseline amount of training before they’re allowed to work underground. The baseline is at least 24 hours of training.

That training builds a practical foundation in safety and health for the underground environment. It covers general mine safety concepts, common hazards unique to underground work, and how to operate and work with equipment and PPE safely. It also teaches how to recognize hazards, understand emergency procedures, and respond appropriately if something goes wrong—like a fire, gas issue, or roof or ventilation problem. In addition, workers learn their rights and responsibilities and the basics of reporting hazards.

This initial 24-hour training is complemented by site-specific and task-specific instruction as the miner starts work, plus periodic retraining as required. Training shorter than 24 hours doesn’t provide the needed baseline for recognizing and avoiding common underground hazards, while longer programs may be used in other contexts, but the minimum to enter underground is 24 hours.
