1. What is the primary responsibility of a Level I Rigger?
A. Operating cranes
B. Rigging and signaling loads
C. Performing crane maintenance
D. Inspecting electrical systems
Rationale: Level I Riggers are responsible for safely rigging loads and signaling
crane operators, not operating or maintaining cranes.
2. Which factor should always be considered first when selecting a sling for a
lift?
A. Color of the sling
B. Load weight
C. Operator preference
D. Type of crane
Rationale: The load weight determines the sling type and capacity needed to lift
safely.
3. What is the minimum angle a sling leg can safely make with the horizontal
when lifting a load?
A. 15 degrees
, B. 20 degrees
C. 30 degrees
D. 45 degrees
Rationale: Angles less than 30 degrees create dangerously high tension in the
sling leg, exceeding rated capacity.
4. Which of the following is a critical pre-lift inspection for slings?
A. Checking color coding
B. Checking for cuts, frays, or broken wires
C. Measuring sling length
D. Checking operator credentials
Rationale: Sling integrity is essential for safety; visual inspections identify
damage that could cause failure.
5. When rigging a load with multiple legs, the load must be:
A. Pulled evenly
B. Balanced to prevent tipping
C. Lifted from one corner first
D. Wrapped with rope
Rationale: Balancing the load prevents tipping or uncontrolled swinging during
lifting.
6. What is the primary hazard of using a damaged wire rope sling?
A. Sling may slip off the load
B. Sling may fail under load
C. Sling may scratch the load
D. Sling may tangle
Rationale: Damaged wire ropes can break unexpectedly, causing injury or load
damage.
7. What does the term "working load limit" (WLL) refer to?
A. Maximum weight a crane can lift
B. Maximum load a sling can safely lift
, C. Maximum distance a load can travel
D. Maximum number of slings in use
Rationale: WLL specifies the safe load a sling can carry, based on its construction
and design.
8. Which type of hitch involves the load being lifted with the sling wrapped
around it and attached at one point?
A. Choker hitch
B. Basket hitch
C. Vertical hitch
D. Double wrap hitch
Rationale: A vertical hitch uses a single point of attachment directly to the load.
9. When should a rigging plan be developed?
A. Only for large loads
B. Only if requested by the operator
C. Before any lift is performed
D. After lifting begins
Rationale: A rigging plan ensures safe handling of all loads and addresses
hazards before lifting.
10.Which type of sling is typically strongest for heavy industrial lifting?
A. Nylon web sling
B. Chain sling
C. Polyester sling
D. Wire rope sling
Rationale: Wire rope slings have high tensile strength and durability for heavy
lifts.
11.What is the purpose of a tag line during a lift?
A. To support the weight of the load
B. To measure the lift height
