Where must directions for resuscitating persons suffering from electric shock be displayed at an underground mine?

Displaying directions for resuscitating persons suffering from electric shock at the surface of the mine where workers assemble before going underground is essential for ensuring that all personnel are aware of the procedures before entering the hazardous underground environment. This location is strategic because it is where workers gather and are briefed about safety measures and emergency protocols. When instructions are visible in this area, it ensures that every employee, regardless of whether they are experienced or new to the worksite, has immediate access to critical safety information before they potentially encounter dangers associated with electric shock.

In contrast, while displaying information in other locations, like underground crib rooms, might seem useful, it would not be the first point of contact for many workers who may not have immediate access to those rooms when entering the mine. Similarly, putting instructions on switchgear associated with portable equipment or in isolated remote control switches does not guarantee that all workers will see them or recall the complex information in a crisis. The primary focus should always be on proactive measures, and ensuring visibility at the surface maximizes the likelihood of that.
