Is it permissible to have a cache located more than 1,000 feet from the face?

The requirement for cache placement is aimed at ensuring the safety and efficiency of mining operations. Generally, having a cache located more than 1,000 feet from the face is not permissible as it could impede quick access to essential tools, equipment, or supplies that miners may need in emergencies or day-to-day operations.

Keeping caches within a specified distance allows for rapid retrieval, which is critical in maintaining operational readiness and safety. This is particularly relevant in situations where quick access to equipment may be necessary during unexpected circumstances, such as equipment failure or emergencies that require immediate response. Therefore, adherence to this guideline is crucial for ensuring compliance with safety regulations in mining operations.

In contrast to this correct situation, the other options suggest varying degrees of flexibility or exceptions that imply a misunderstanding of the strict safety protocols that govern cache placements. It's important for all personnel to understand these limitations to maintain a safe working environment in the mines.
