1. What is the primary purpose of a pre-operation inspection?
A. To speed up equipment start-up
B. To identify hazards or defects before operating
C. To satisfy regulatory requirements
D. To check fuel levels only
Rationale: Identifying hazards or defects early prevents
accidents and equipment failure.
2. Which document outlines the safe way to perform a specific
task with equipment?
A. Site map
B. Job safety analysis (JSA)
C. Load chart
D. Operator’s log
Rationale: A JSA breaks down tasks and identifies hazards and
safety controls.
,3. What should an operator do if a safety alarm on equipment
activates?
A. Ignore it if the machine still functions
B. Continue operating at reduced speed
C. Stop the equipment and investigate the cause
D. Reset the alarm and resume
Rationale: Safety alarms signal conditions requiring
immediate attention to prevent accidents.
4. Which factor most affects equipment stability?
A. Paint color
B. Tire size
C. Fuel level
D. Center of gravity
Rationale: Stability relies on maintaining the center of gravity
within the equipment’s base of support.
5. When lifting with a crane or loader, the operator should
always:
A. Lift quickly to reduce load time
B. Keep the load as low to the ground as possible
C. Lift with attachments fully extended
D. Lift while making sharp turns
Rationale: Keeping loads low improves stability and reduces
tip-over risk.
, 6. What should an operator do before backing heavy
equipment?
A. Rely solely on mirrors
B. Use a spotter when available
C. Back up as quickly as possible
D. Ignore blind spots
Rationale: Using a spotter reduces blind-spot hazards and
improves safety.
7. When operating on a slope, the safest method is to:
A. Travel sideways across the slope
B. Travel straight up and down the slope
C. Reverse up the slope
D. Travel diagonally
Rationale: Traveling straight up/down minimizes lateral tip-
over risk.
8. Which is a sign of hydraulic system failure?
A. Clean hoses
B. Visible fluid leaks
C. Slight dust accumulation
D. Cool operating temperature
Rationale: Hydraulic leaks indicate damaged lines or seals that
can lead to system failure.
