These 10 free CSPR-1 questions are organized by exam domain, so you can see how each part of the Certified Signal Person and Rigger Level 1 blueprint is tested. Reveal the answer and explanation under each question.
During an elevator-machine pick, the signal person extends one arm horizontally, points the thumb upward, and repeatedly opens and closes the fingers. What combination of crane motions is being requested?
Correct answer: A - Raise the boom and lower the load.
The load needs to rise eighteen inches at slow speed, with no change in boom angle. Which spoken sequence correctly directs that movement from start to stop using OSHA's voice-signal order?
Correct answer: B - Hoist up. Eighteen inches, slowly. Hoist stop.
As a fixed-length crane boom is slowly lowered, the load-weight display stays steady but the rated-capacity indicator rises from 62% to 84%. The crane remains level, and the load is clear of obstructions. Which explanation best fits these readings?
Correct answer: B - The larger radius leaves less rated capacity for the same load.
The utility confirms that a nearby energized overhead line is 115 kV. The employer uses OSHA's Table A clearance option and has implemented the required encroachment controls. The crane, load line, load, and rigging will remain at least 17 ft from the line throughout the lift; the route does not pass beneath it. What does Table A establish about this plan?
Correct answer: C - The 15-ft minimum is met; the encroachment controls must remain in place.
For a level, symmetrical lift of a 6,000-lb machine, two equal wire-rope sling legs will each be 45 degrees above horizontal. Rigging weight is negligible, and all connections and bearing diameters are approved. What is the lowest individual-leg working load limit (WLL) listed that passes the static tension check? Use sin 45 degrees = 0.707.
Correct answer: C - 4,500 lb
A wire-rope choker will be formed with a Crosby screw-pin shackle. The sling body must slide at the choke as slack is taken up. The shackle is correctly sized and rated, and its matched pin is fully engaged and tightened. How should the shackle be oriented?
Correct answer: D - Sling eye over the pin; moving sling body centered in the bow.
A pre-use inspection finds a cut in a polyester roundsling's cover that exposes the core yarns. No visible core yarn is severed, and the identification shows adequate capacity for the planned lift. A coworker argues that the cover does not carry the load. How should the rigger assess the sling?
Correct answer: C - Exposed core yarns are sufficient reason to remove the sling from service.
A crane's chart for the verified setup lists 8,000 lb at a 40-ft radius and 6,000 lb at a 50-ft radius. These are total suspended-load limits, including the payload, hook block, and lifting gear. Between listed radii, the manufacturer requires the next larger radius; interpolation is prohibited. The planned path reaches 46 ft. The machine weighs 4,600 lb, the hook block 350 lb, and the lifting gear 450 lb. There are no other deductions. Which entry correctly completes the lift-plan capacity check?
Correct answer: A - Pass: 5,400 lb total suspended load against 6,000 lb available capacity.
At a construction site, a mobile crane is landing an elevator machine on prepared supports. A qualified rigger has secured it against unintended displacement, and the hook has a self-closing latch. One employee is needed to guide the machine from beside it, without standing underneath. An apprentice wants to enter solely to observe. Under OSHA's load-landing rule, who may enter the fall zone during this operation?
Correct answer: D - Only the employee needed to guide and receive the machine during landing.
For a construction lift in an area with caustic cleaning mist, which synthetic web sling is eligible for consideration under OSHA's material restrictions? Suitability for the actual chemical concentration and temperature must still be confirmed with the manufacturer.
Correct answer: A - Nylon webbing with steel fittings.
