What should be marked on rigging gear to denote its WLL?

The correct answer is that rigging gear should have manufacturer specifications and safety labels marked on it to indicate its Working Load Limit (WLL). These specifications and safety labels provide critical information regarding the maximum load that the rigging equipment can safely handle under specific conditions. This includes details about the material, design, and any relevant safety factors that have been considered during the design process.

Manufacturer specifications and safety labels are essential for ensuring safety on the job. They help riggers and operators assess whether the gear is appropriate for the intended lifting task. If this information were absent, it could lead to the misuse of the rigging equipment, resulting in potentially dangerous situations, equipment failures, or accidents.

Other options such as color-coded tags are useful for identification and organization but do not typically convey WLL information effectively. While the owner's name and contact information are important for ownership identification, they do not pertain to the load capacity of the rigging equipment. Maintenance schedule dates are essential for ensuring gear is in good condition, but they do not include specific information regarding the WLL.
