What record is required of miners entering or leaving the mine?

• A. The mines tracking system and the check-in check-out board
• B. The payroll ledger
• C. The safety training log
• D. The emergency contact book

Answer: (D)

Having an emergency contact book on file for each miner is a safety requirement that ensures rapid communication with families or designated contacts during an incident. When someone enters or leaves the mine, this record provides the immediate point of contact for notifying relatives, coordinating rescue or medical actions, and confirming who is underground. While tracking systems or a check-in/check-out board help prove who is present at any moment, the emergency contact information specifically enables quick, organized communication in emergencies. Other records like payroll or safety training logs serve different purposes—pay and training history—not the urgent need to reach a person who can provide or relay critical information during an incident.
