What procedure must outside contractors follow to access the roof?

Outside contractors must provide a fall protection program for approval to access the roof because ensuring safety is critical in environments where there is a risk of falling from heights. The fall protection program outlines the safety measures and equipment that will be used to minimize the risk of injury. It demonstrates the contractor's commitment to adhering to safety regulations and best practices while working on elevated surfaces. This protocol ensures that both the contractors and the facility are safeguarded against potential accidents.

While other options may contribute to safety and communication, they do not specifically address the vital requirement of having a structured plan for protecting individuals from fall hazards, which is why the fall protection program is the necessary step for accessing the roof.
