In safety factor calculations for rope handling, which document provides the minimum factor?

• A. 2
• B. Naval Engineering Manual
• C. 5
• D. 10

Answer: (B)

In rope handling, you establish a margin between what the rope can carry and the load you expect to impose. That margin is expressed as a safety factor, which is the rope’s strength divided by the anticipated load. To ensure a consistent baseline across operations, the Navy codifies a minimum safety factor in an official document. The Naval Engineering Manual is the authoritative source for rigging and rope-handling practices, and it specifies the minimum factor to be used in calculations. Because it’s a document, it provides a standardized baseline that numbers alone don’t establish. In practice, you can use a higher factor if the risk assessment calls for it, but the minimum comes from the Naval Engineering Manual.
