Question 91: What action must be taken under OSHA standards if a crane is found to have a safety defect during inspection?

The crane must be taken out of service until the defect is corrected (Correct answer)
Operations may continue at 50% rated capacity until repairs are made
The defect must be tagged and repairs completed within 30 days
The defect must be reported to OSHA within 24 hours

Correct answer: The crane must be taken out of service until the defect is corrected

OSHA requires that cranes with safety defects be taken out of service immediately and not returned to service until the defect is corrected.

Question 92: What is the primary purpose of outriggers on a mobile crane?

To increase the boom length for greater reach
To anchor the crane to the ground permanently
To stabilize the crane and increase its lifting capacity (Correct answer)
To lower the center of gravity during transport

Correct answer: To stabilize the crane and increase its lifting capacity

Outriggers extend from the crane's lower works to provide a wider, more stable base, which increases tipping resistance and allows higher lifting capacities.

Question 93: How frequently should ongoing assessments be conducted in Rigger and Signal Person Certification practice?

At regular intervals and as conditions change (Correct answer)
Once annually regardless of circumstances
Only when required by external auditors
Only when problems are reported

Correct answer: At regular intervals and as conditions change

Ongoing assessments should follow established protocols and also respond to changing conditions.

Question 94: What does the ASME/ANSI standard hand signal for 'move slowly' require the signal person to do?

Wave both arms slowly over their head
Point in the direction of movement with one finger
Place one hand motionless above the moving hand signal (Correct answer)
Cross both arms in front of the body

Correct answer: Place one hand motionless above the moving hand signal

The 'move slowly' signal is given by placing a stationary hand above the hand giving the directional motion signal.

Question 95: Which of the following is a common cause of crane overturn during lifting operations?

Lifting a load that exceeds the rated capacity or operating on unstable ground (Correct answer)
Having too much counterweight installed for the boom length used
Operating in ambient temperatures below 40°F
Using a load chart that is two years old

Correct answer: Lifting a load that exceeds the rated capacity or operating on unstable ground

Exceeding the crane's rated capacity or operating on ground that cannot support the crane's loads are the most common causes of crane overturn during lifting operations.

Question 96: How should rigging angles be managed?

Manage angles properly (Correct answer)
Use the widest angle possible
Ignore angles
Use the narrowest angle regardless

Correct answer: Manage angles properly

Rigging angles must be managed properly because they significantly impact the tension and stress on slings and other rigging components. As the angle between the sling legs decreases (becomes wider), the tension in each leg increases dramatically, potentially exceeding the sling's Working Load Limit. Understanding and calculating these forces is crucial to prevent overloading and ensure safe lifting operations.

Question 97: When new equipment is introduced in Rigger and Signal Person Certification, what is REQUIRED before staff use it?

A brief verbal overview
Formal training, competency verification, and documentation (Correct answer)
