What must all personnel ensure when working near the low point?

Maintaining a distance of 25 feet when working near the low point is crucial for ensuring the safety of all personnel involved. This distance serves as a buffer zone that helps to prevent accidents and protects individuals from potential hazards associated with the Skycoaster's operation, particularly during launch and landing phases. The low point is where the coaster finishes its ride and is a critical area where the risk of injury can be heightened due to the motion and the interaction with the flight crew and the equipment. Keeping this specified distance allows workers to avoid any potential collisions or entrapment issues, ensuring that they are not in the path of the Skycoaster as it approaches the ground.

While wearing safety gear is always recommended and informing the flight crew of one’s presence are also important safety measures, the specific requirement of maintaining a distance of 25 feet is a standard protocol that directly addresses physical safety in that specific operational context. Staying out of sight is less relevant since personnel still need to be visible to the crew to communicate effectively about the operation.
