What is the required temperature setting for the dryer?

The correct choice of 60 Degrees Celsius for the required temperature setting for the dryer is based on ensuring that the drying process is effective for equipment and materials used in mining rescue operations. This temperature is typically sufficient to remove moisture efficiently without risking damage to the materials. Setting the dryer at this temperature ensures that the equipment is sanitized, as higher temperatures can effectively eliminate harmful bacteria and mold that could compromise the safety and functionality of the gear.

In contrast, temperatures that are too low, such as those in the other options, may not entirely dry the equipment, leading to potential issues such as mold growth or equipment malfunction. Selecting a temperature that is not optimal could also impact the overall preparation and readiness of the rescue team, which is crucial in emergency situations. Therefore, setting the dryer to 60 Degrees Celsius balances efficiency and safety for mine rescue operations.
