Question
What is meant by “100% tie-off” regarding tower safety?
Answer Options
- A) All loose ropes and guys secured to a fixed structure
- B) At least one lanyard attached to the tower at all times
- C) All tools secured to the climber’s harness
- D) All circuit breakers feeding power to the tower must be tied closed with tape, cable, or ties
Correct Answer: B
Explanation
The most important safety rule when climbing or working on an antenna tower is fall protection. A standard safety harness alone is insufficient; the climber must be positively attached to the structure at all times to prevent a fall, which can be fatal.
“100% tie-off” is the safety mandate that means At least one lanyard attached to the tower at all times. The climber should use two lanyards: as they move past a structural obstruction, they attach the second lanyard before unhooking the first, ensuring that there is never a single moment when they are not securely attached to the tower, thereby eliminating the risk of free fall.
