1. A self-retracting lifeline would be used when working at which height?

A. 20.5'
B. 16'
C. 19'
D. 21'

Answer :

When working at heights, self-retracting lifelines are commonly used as part of fall protection systems to keep workers safe. Fall protection is generally required at heights above 6 feet, but self-retracting lifelines are often specifically used for greater heights where the risk of falling is more significant.

For this particular question, we're looking for the height at which a self-retracting lifeline would be used. Let's review the options provided:

- A. 20.5 feet
- B. 16 feet
- C. 19 feet
- D. 21 feet

While fall protection is necessary at any height above 6 feet, self-retracting lifelines are more commonly associated with significant heights due to their design to offer maximum safety and control in the event of a fall.

Out of the given options, 20.5 feet is a significant height that typically justifies the use of such equipment to ensure safety. It's a height where the benefits of a self-retracting lifeline would be most apparent due to the increased risk associated with potential falls.

Therefore, the most likely height among the given options where a self-retracting lifeline would be used is:

A. 20.5 feet
