Final answer:
In rigging, master links, shackles, wire rope, and all other rigging hardware must be capable of supporting at least 5 times the maximum intended load without failure. This is known as the safety factor.
Step-by-step explanation:
In rigging, master links, shackles, wire rope, and all other rigging hardware must be capable of supporting at least 5 times the maximum intended load without failure. This is known as the safety factor. The safety factor ensures that there is a margin of safety to account for any unforeseen factors or stress on the rigging equipment.
For example, if the maximum intended load is 1000 pounds, the rigging hardware must be capable of supporting at least 5000 pounds without failure. By having a safety factor of 5, it helps to prevent accidents and ensures the stability and reliability of the rigging system.
