To what should lanyards be attached while climbing?
The correct answer is D: Tower legs. Lanyards should be attached to tower legs while climbing. Tower legs are the main structural members and provide the strongest, most secure attachment points.
Tower legs are the primary structural elements of a tower - the vertical members that support the entire structure. They're designed to carry the tower's load and are the strongest points. Lanyards should be attached directly to the tower legs, not to secondary elements like antenna masts, guy brackets, or tower rungs. Legs provide the most secure attachment and won't fail under the load of a falling climber. Attaching to weaker elements like brackets or rungs could fail in a fall. Tower legs are the proper, safe attachment points for fall protection equipment.
Exam Tip
Lanyard attachment = Tower legs. Remember: Lanyards should be attached to tower legs while climbing - the legs are the primary structural members and provide the strongest, safest attachment points.

Real-World Application
You're climbing a tower. You attach your lanyard directly to the tower leg (the main vertical structural member). This is the strongest point and will safely support you if you fall. You don't attach to the antenna mast, guy brackets, or rungs - those aren't designed for fall protection loads. Tower legs are the proper attachment points.

Why Other Options Are Wrong
Option A: Incorrect. Antenna masts are not as strong as tower legs and shouldn't be used for lanyard attachment. Legs are the primary structure.
Option B: Incorrect. Guy brackets are attachment points for guy wires, not designed for lanyard loads. They could fail in a fall.
Option C: Incorrect. Tower rungs are for climbing, not for lanyard attachment. They're not designed to support fall protection loads and could fail.
