What must be done after supplies are transported using belts prior to transporting miners?

After supplies are transported using belts, it is crucial to examine for unsafe conditions before transporting miners. This step is designed to ensure the safety and well-being of all personnel involved. The transportation of supplies may lead to potential hazards such as fallen materials, spillage, or equipment malfunction that could pose risks to miners who are about to use the same transport system. Conducting a thorough examination allows for the identification and mitigation of any unsafe situations, ensuring that the environment is secure for those who will be traveling afterward.

While checking for mechanical issues, oiling the belts, and ensuring proper weight limits are all important aspects of equipment maintenance and safety, the priority in this scenario is on assessing the operational environment regarding safety conditions. Addressing these unsafe conditions first helps prevent accidents and injuries, making it a critical step in the process.
