a good rule of thumb is to stay 6 feet or more away from the centerline of an active antenna. T or F
- correct answer True
when you are using synthetic rope for lifting loads everyday, how often should it be inspected?
- correct answer daily
at minimum, how often should a competent rigger have refresher training?

if a synthetic rope has a breaking strength of 7,600 lbs, what is the maximum gross load that can be
lifted?

when must a hard hat be worn?
