Before use on ATON vessels, blocks without a safe working load stamp must be what?

Explanation:
Blocks used on ATON vessels must have a known safe working load. If a block arrives without that stamped rating, you can’t assume it will hold any particular load. The correct action is to proof test the block before use. A proof test subjects the gear to the specified load or an over-limit load to confirm it can withstand service without deformation or failure, thereby validating its strength and allowing a safe working load to be assigned. Repainting could hide a stamp, photographing doesn’t verify strength, and daily inspections, while important, don’t establish the actual load-carrying capability.
