According to OSHA, how should power supply to the runway be controlled?

The correct approach according to OSHA regarding controlling the power supply to the runway is through the use of a switch or circuit breaker. This ensures that there is a means to safely and quickly disconnect the power supply in case of an emergency or maintenance situation. Using a switch or circuit breaker provides a reliable and safe way to manage electrical supply; it allows for clear visibility and accessibility, ensuring operators can take action without unnecessary risks.

In addition, reliance on just the main power switch alone may not offer the same level of flexibility and safety, especially if the switch is remote or hard to access in an emergency. While operating remotely from a control room provides a measure of distance from the equipment, it may delay response time in critical situations where immediate power disconnection is needed. Lastly, manual control by the operator is not an ideal method, as it can introduce errors or delays, especially under stressful conditions. Prioritizing safety and efficiency is crucial, which is why the switch or circuit breaker is the preferred method for controlling the power supply.
