Stop and start controls on a belt conveyor not used for miners must be installed at least every how many feet?

• A. At least every 500 feet
• B. At least every 2000 feet
• C. At least every 1500 feet
• D. At least every 1000 feet

Answer: (D)

The safety principle here is that a belt conveyor should be stoppable quickly from any point along its length. To make that possible, controls to stop and start the belt must be placed so that no point on the belt is more than 1000 feet away from a control. This maximum spacing ensures rapid shutdown in an emergency or when the belt needs to be halted for safety, even if miners aren’t working directly on the belt. So, controls should be installed at intervals of 1000 feet or less along the belt run. For a long belt, you’d space them accordingly (for example, at the start and then every 1000 feet). Shorter spacing would still satisfy the rule, while longer gaps would not meet the requirement.
