What is the minimum length required for tails used in rigging knots?

The minimum length required for tails in rigging knots is typically set at 100mm. This length is important because it ensures that there is enough excess rope to provide a secure knot, reducing the risk of accidental loosening or slipping. Adequate tail lengths also facilitate easier inspection of the knot and allow for a more effective hold when under tension. The choice of 100mm balances the need for security with practicality, as excessively long tails can be cumbersome and lead to tangling, while insufficient tail lengths may compromise the integrity of the knot itself. Proper knot tying is crucial in rope access work, making adherence to these guidelines essential for safety and performance.
