After any structure repair or modification, what percentage should the platform be tested to?

The correct answer is based on established safety standards related to structural integrity and load testing after modifications or repairs. When a platform or any structure undergoes repairs or modifications, testing it to 150% of its maximum intended load ensures an additional safety margin. This increased testing percentage is crucial because it accounts for unforeseen factors, potential overload conditions, and the integrity of the repairs or modifications made.

By applying a higher load during the test, professionals can verify that the structure can bear more than the expected load during regular operation, thereby ensuring safety and compliance with regulations. It inherently addresses concerns about any weaknesses that might have been introduced during the repair or modification process. This approach is vital to ensure both worker safety and the reliability of the structure, making 150% the standard for testing post-repair or modification.
