What is the safety factor for all other types of rigging?

• A. 5 to 1
• B. 4 to 1
• C. 3 to 1
• D. 6 to 1

Answer: (A)

In rigging practice, the safety factor is the ratio of the gear’s breaking strength to the maximum load you expect to lift, providing a margin for shock, dynamic forces, and wear. For all other types of rigging, the standard safety factor is five to one. This means the equipment used should have a breaking strength at least five times the anticipated load, helping to prevent failure under real-world conditions.

The other options would either reduce the margin too much (three to one or four to one), risking overload, or be more conservative than necessary (six to one) for general use. Sticking with five to one keeps a practical, widely accepted balance for most rigging scenarios.
