What is the maximum distance first-aid equipment must be maintained outby the longwall working face?

The correct distance at which first-aid equipment must be maintained outby the longwall working face is 150 feet. This requirement ensures that workers have immediate access to first-aid resources in the event of an injury, which is crucial in the mining environment where emergencies can occur suddenly. Keeping the equipment within this distance allows for a quicker response to injuries, minimizing the time taken to administer aid, which can be critical for the health and safety of the miners.

This standard reflects the importance of preparing for emergencies and making sure that necessary medical assistance is quickly available. While other distances might seem reasonable, they do not meet the specific safety standards established for the industry that emphasize both accessibility and the urgency of care. Having the first-aid equipment at this specified distance balances practical accessibility with operational safety considerations in the mine.
