Question 598

To what should lanyards be attached while climbing?

Antenna mast
Guy brackets
Tower rungs
Tower legsCorrect answer

Explanation

The legs are the primary load-bearing members of a tower, carrying loads down into the foundation, and they are the point the official pool names for lanyard attachment. Rungs and step bolts are climbing aids rather than designated fall-arrest anchorages, and guy brackets and the mast sit outside the tower's main load path.

Pool question E0A11. Standard practice: on a lattice tower the legs are the primary structural members, and the legs are what the official question pool identifies as the lanyard attachment point, rather than rungs, guy brackets or the mast. For context, 29 CFR 1926.502(d)(15) requires an anchorage for personal fall arrest equipment to be capable of supporting at least 5,000 pounds (22.2 kN) per attached worker unless it is designed, installed and used under the supervision of a qualified person as part of a system with a safety factor of at least two — a requirement that points towards structural members rather than fittings, without in itself certifying any particular tower leg.
