Dated records of inspections must be made and kept by the platform user for the duration of what operation?

The correct choice highlights that dated records of inspections must be maintained by the platform user for the duration of personnel lift operation. This is essential because personnel lifts, such as aerial work platforms, are used in environments where the safety of workers is paramount. Keeping detailed inspection records ensures that the equipment is in good working condition and meets safety standards, which directly impacts the safety of personnel using the lift.

Regular inspections are critical for identifying potential hazards, ensuring compliance with safety regulations, and safeguarding against accidents. Documentation serves as proof that proper maintenance procedures have been followed and allows for accountability. In environments where personnel lifts are operated, having accurate records readily available can be vital during safety audits or inspections by regulatory bodies.

For the other choices, while equipment maintenance, safety training sessions, and load testing schedules are all important aspects of operational safety, they do not specifically emphasize the necessity of maintaining dated records for the ongoing operation of personnel lifts. Instead, they relate to general practices surrounding equipment and personnel safety rather than the continuous documentation required for lift operations.
