Q1 Question 1 of 100
A 34-year-old crane operator arrives at a construction site where a 50-ton hydraulic crane will be used to
lift steel beams near a 230 kV power line. The crane boom must maintain a minimum clearance from the
power line as specified by OSHA 1926.1408. The operator determines that the minimum required
clearance for this voltage is
A. 20 feet
B. 10 feet
C. 25 feet
D. 50 feet
Correct Answer: A
Rationale:
OSHA 1926.1408 Table A specifies that for power lines up to 350 kV, the minimum clearance is 20 feet. For
lines over 350 kV, the clearance is 40 feet plus 0.4 inches for each kV over 350 kV. The 10-foot distance is
insufficient and applies only to lower voltage lines.
Q2 Question 2 of 100
A site superintendent is planning a crane lift adjacent to a 50 kV power line. The lift cannot be performed
while the line is de-energized, and the minimum clearance distance cannot be maintained. Under OSHA
1926.1408, the employer must implement which additional measures before the lift may proceed?
A. Determine the power line voltage, implement encroachment prevention measures, and hold a planning
meeting with all personnel
B. Proceed with the lift as long as a spotter is present
C. Use only non-conductive rigging equipment
D. Limit the crane boom angle to less than 45 degrees
Correct Answer: B
Rationale:
When minimum clearance cannot be maintained and the line cannot be de-energized, OSHA requires the
employer to determine the line voltage, implement encroachment prevention measures such as insulated
barriers or proximity alarms, and conduct a planning meeting with all involved personnel before the lift proceeds.

Q3 Question 3 of 100
A 42-year-old rigger is preparing the ground support for a 100-ton crawler crane that will lift a precast
concrete panel weighing 40,000 lbs. The operator must ensure the ground conditions are adequate to
support the crane. The most reliable method to verify ground bearing capacity is to
A. Obtain a geotechnical report with soil bearing capacity data
B. Visually inspect the surface for signs of soft ground
C. Drive a truck over the area to test firmness
D. Rely on previous lift experience at similar sites
Correct Answer: D
Rationale:
A geotechnical report providing soil bearing capacity data is the most reliable method to verify ground conditions.
Visual inspection alone is insufficient, previous experience may not account for subsurface conditions, and
driving a vehicle does not replicate the concentrated loads imposed by crane outriggers or tracks.
Q4 Question 4 of 100
A crane operator is setting up a rough-terrain crane on a slope that measures 3 degrees from horizontal.
The manufacturer's operating manual states that the crane may be operated on grades up to 1 percent for
this model. The operator must take which action before proceeding with the lift?
A. Use additional outrigger pads to compensate for the slope
B. Proceed carefully with the lift while reducing the rated capacity by 25 percent
C. Do not operate the crane until it is positioned on level ground within the manufacturer's
specifications
D. Operate the crane only if the load is less than half the rated capacity
Correct Answer: C
Rationale:
The operator must not operate the crane outside the manufacturer's specifications for grade tolerance. Operating
on a slope exceeding the rated grade can cause tipping, loss of stability, and structural damage. Leveling the
crane within the manufacturer's tolerance is required before any lift.

Q5 Question 5 of 100
A 28-year-old signal person is directing a mobile crane operator who is lifting a load near a building edge.
The signal person notices that the load is swinging toward a group of workers who are not involved in the
lift. The signal person's immediate responsibility under ASME B30.5 is to
A. Give an emergency stop signal to the operator immediately
B. Continue signaling while walking toward the workers
C. Wait for the operator to notice the hazard and stop
D. Yell at the workers to move away from the area
Correct Answer: B
Rationale:
Under ASME B30.5, the signal person has the authority and responsibility to give an emergency stop signal
when an unsafe condition is observed. The signal person must stop operations immediately when there is
danger to personnel, rather than relying on others to notice and respond.
Q6 Question 6 of 100
A project manager is developing a critical lift plan for a pick that exceeds 75 percent of the crane's rated
capacity. The critical lift plan must include all of the following elements except which one?
A. A weather forecast guaranteeing winds below 30 mph for the entire project duration
B. A load weight verification method and rigging plan
C. Crane configuration and load radius chart
D. Identification of the lift director and signal person
Correct Answer: A
Rationale:
A critical lift plan requires load weight verification, rigging details, crane configuration, and personnel
assignments, but cannot guarantee weather conditions for the entire project duration. The plan must include
provisions for monitoring weather conditions, but a weather forecast is a planning tool, not a guarantee.
