What should be provided where miners are required to cross moving belts?

The correct choice emphasizes the importance of ensuring safety and accessibility for miners when they need to cross moving belts. Providing suitable crossing facilities, such as walkways or bridges, allows for safer passage over potentially hazardous areas with moving equipment. These structures are designed to minimize the risk of accidents by keeping the miners away from the moving parts of the belts while offering a designated pathway that maintains both safety and efficiency in the mine’s operations.

In this context, other options may address safety, but they do not specifically maximize the safe crossing of moving belts. Safety nets, for instance, could be useful in preventing falls, yet they do not provide a means for crossing. Stop signs might alert workers to the danger but do not offer a practical solution for crossing hazards safely. Manual overrides could allow workers to stop the equipment, but this does not fundamentally address safe crossing. Overall, suitable crossing facilities are critical in allowing miners to navigate the worksite safely and efficiently.
