How many feet outby the longwall face must first aid equipment be maintained?

First aid equipment must be maintained at a specific distance outby the longwall face to ensure that it is readily accessible in case of an emergency. Keeping it 150 feet outby strikes a balance between being close enough to respond quickly during an incident, yet far enough to avoid potential hazards associated with the immediate area around the longwall face. This guideline is crucial for ensuring the safety of miners working in high-risk environments, where injuries may require prompt medical attention. The 150-foot requirement is established based on safety regulations aimed at protecting workers while ensuring the tools necessary for first response are available without compromising safety.
