Before a spreader bar or beams can be used they MUST have been:

The correct answer, which emphasizes that spreader bars or beams must have been tested and approved before their use, is crucial for ensuring safety and compliance in rigging operations. Testing verifies that the equipment can support the expected loads and meets industry standards regarding structural integrity and functionality. This process helps to identify any potential issues that could lead to equipment failure during operations, which could pose a serious safety risk to the crew and equipment on site.

Testing and approval might involve evaluating the equipment for wear and tear, confirming load capacity, and ensuring that materials have not been compromised. This step is not only a best practice but is often mandated by regulatory bodies to prevent accidents and ensure the safe handling of loads.

Other options mention either repainting, prior use, or upgrades, which, while perhaps relevant in specific contexts, do not fundamentally establish the crucial prerequisite of verifying the safety and reliability of the equipment through formal testing. An item may be repainted or used in the past, but without proper testing and approval, there is no guarantee that it remains in a safe working condition. Upgrading from a previous job does not ensure the equipment's current suitability without confirming its load-bearing capabilities through testing.
