What is meant by “100% tie-off” regarding tower safety?
All loose ropes and guys secured to a fixed structure
At least one lanyard attached to the tower at all times✓Respuesta correcta
All tools secured to the climber’s harness
All circuit breakers feeding power to the tower must be tied closed with tape, cable, or ties
Explicación
One hundred percent tie-off means the climber is never disconnected from the structure: two lanyards are used alternately so that one stays anchored while the other is moved past an obstruction. Securing tools or guy lines is sound practice but is a different matter, and it says nothing about the climber's own fall protection.
