Mines employing fifty or more men underground at any one time shall maintain which of the following organizations capable of sustaining operation during an emergency until outside help is available?

• A. Mine Rescue Organization
• B. Emergency Response Unit
• C. Safety Committee
• D. First Aid Team

Answer: (A)

The key idea is that a specialized on-site capability is needed to handle underground emergencies long enough for outside help to arrive. A mine rescue organization is built exactly for this role: trained to operate in hazardous conditions underground, with the equipment, procedures, and coordination skills to search, rescue, control the scene, monitor gases, manage ventilation, and sustain operations until external responders can take over. They can stay on scene, work safely in dangerous environments, and ensure survivors and trapped miners are found and protected while outside help is en route.

Other groups serve important safety functions—an emergency response unit may handle initial containment and coordination, a safety committee focuses on preventive measures and policy, and a first aid team provides medical care—but none are specifically trained or equipped to operate underground for extended periods during a mining emergency. The mine rescue organization uniquely fills that critical, sustained capability requirement.
