At what distance should warning lights or reflectors be installed along haulage roads?

The installation of warning lights or reflectors at abrupt changes in clearance is crucial for ensuring the safety of mine haulage roads. These changes in clearance can pose hazards for operators, including the potential for collisions and accidents, especially in dimly lit or poorly marked areas. By placing warning lights or reflectors specifically at these critical junctures, it enhances visibility and alerts operators to potential dangers in the path ahead.

This approach allows for targeted safety measures that address specific risks rather than a blanket solution that might not adequately cover all hazardous areas. While regular intervals could be useful in some scenarios, they may not adequately identify the most dangerous points where immediate attention is required, such as areas with sudden elevation changes or clearance issues. Thus, focusing on those abrupt changes ensures that operators are forewarned about significant risks, promoting safety and preventing incidents in the mine environment.
