What must occur after structural repairs or alterations of a platform?

Following structural repairs or alterations of a platform, conducting a proof test at 150% of its intended capacity is essential to ensure the safety and integrity of the structure. This proof test serves multiple purposes: it verifies that the repairs have been properly executed, confirms that the platform can withstand loads beyond its design limit, and helps to identify any potential weaknesses that may not have been apparent during the repair process.

Testing at 150% of capacity provides a significant safety margin, which is crucial in construction and rigging environments where the consequences of failure can be severe. This level of testing ensures that any residual stresses or flaws induced during the repair do not compromise the platform's performance. It is a standard practice in rigging and structural engineering to validate the safety and reliability of the structure before it is put back into service, ensuring that it can handle anticipated loads safely.
