OSHA 29 CFR 1926.1412 requires that the annual inspection be performed by a qualified person, meaning someone with specific knowledge and training.

Question 85: A rigger is lifting a steel beam and notices it will pass over workers below. What action is required?

Sound the crane horn twice before hoisting to warn workers
Post a warning sign at the perimeter and continue the lift
Reduce lift speed to minimum to give workers time to move
Clear all personnel from the area beneath and swing path of the load (Correct answer)

Correct answer: Clear all personnel from the area beneath and swing path of the load

OSHA prohibits carrying loads over workers; the entire area beneath the load's path must be cleared of all personnel before and during the lift.

Question 86: What does the hand signal of tapping the top of the head with a fist, then using regular signals, indicate?

Activate the emergency stop
Engage the crane's load line brake
Use the whip line (auxiliary hoist)
Use the main hoist (Correct answer)

Correct answer: Use the main hoist

Tapping the top of the head with a fist before a signal indicates that the main hoist should be used for the following command.

Question 87: What distinguishes a Rigger and Signal Person Certification certified professional from a non-certified practitioner?

There is no meaningful difference
Certified professionals always have more experience
Certified professionals only work in larger organizations
