Where are the rules for distribution barriers applied?

• A. <100 m outbye from the face
• B. Within the face zone
• C. <30 m outbye from belt boot or Feeder Breaker
• D. <30 m outbye from trickle duster/ aux fan

Answer: (B)

Distribution barriers are about containing electrical hazards where the risk is highest: at the active face. The face zone is the area immediately around the working face where mining and development occur, and where electrical equipment and power distribution present the greatest potential for hazards to workers. Placing distribution barriers within this zone limits the spread of faults or arcs and protects crews as they operate near the face, without relying on barriers further outbye. Distances outbye from the face or from specific pieces of equipment are not where these rules apply; those distances relate to other safety controls. So the rules for distribution barriers are applied within the face zone.
