Hazardous weather stop

Definition

The federal rule that stops rope work in wind and deliberately names no number.

Why It Matters

The rope descent standard says no employee uses the system when hazardous weather such as storms or gusty or excessive wind is present, and it stops there: no miles per hour appears anywhere in it, and the call belongs to a qualified person. The number the trade repeats is not from that rule at all. Twenty-five miles per hour is a DESIGN figure in the consensus standard for stabilizing hardware on long descents, which is a specification for equipment and not a stop-work trigger. So the threshold this business actually runs on is whatever its own written plan says, which makes that document the thing to read. A company with no number of its own has left the decision to whoever is on the roof.
