Class D mines and service contractors shall have at least which personnel?

• A. 1 part time Safety Engineer and 1 full time Safety Inspector
• B. 1 part time Safety Engineer, 1 part time Safety Inspector
• C. 2 part time Safety Engineers and 1 full time Safety Inspector
• D. 1 full time Safety Engineer and 1 part time Safety Inspector

Answer: (A)

Minimum staffing for Class D mines and service contractors centers on providing both engineering safety oversight and on-site safety supervision. You need a Safety Engineer to handle engineering aspects of safety—design reviews, hazard analysis, and verification that safety systems meet standards. That role is covered part-time, reflecting that engineering oversight can be scaled with the operation’s needs while still ensuring essential checks are in place. On the other hand, a Safety Inspector must be on-site full-time to conduct ongoing safety inspections, enforce rules, identify hazards in daily operations, and respond promptly to safety concerns. Together, this pairing—part-time Safety Engineer and full-time Safety Inspector—gives essential engineering controls plus continuous on-site oversight, which is the minimum required. Other patterns either add more personnel than necessary or place the time commitments differently (for example, a part-time inspector or two part-time engineers), which do not meet the stated minimum.
