A qualified rigger, under OSHA, is a worker whom the employer has verified can safely rig loads for crane lifts, either by holding a recognized degree, certificate, or professional standing, or by having extensive knowledge, training, and experience, and who can demonstrate the ability to solve problems that come up when rigging the specific loads on the job. OSHA does not issue a rigger license or card. The qualification is a determination the employer makes, tied to the actual work in front of the rigger, and federal regulations require that determination in two situations: crane assembly and disassembly, and any lift where workers are in the fall zone of the load.
How OSHA Defines the Role
The regulatory definition sits in 29 CFR 1926.32. A “qualified person” is someone who, by possession of a recognized degree, certificate, or professional standing, or by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems related to the subject matter, the work, or the project.1Occupational Safety and Health Administration. 29 CFR 1926.32 – Definitions
The demonstration piece is what separates a qualified rigger from someone who has simply taken a class. Qualification attaches to the job, not to the person in the abstract. A rigger with years of experience hoisting steel beams is not automatically qualified to rig an oddly shaped piece of mechanical equipment with an off-center center of gravity. The employer has to evaluate whether the individual can handle the particular loads, equipment, and conditions of the project at hand.2Occupational Safety and Health Administration. Subpart CC – Cranes and Derricks in Construction: Qualified Rigger
When OSHA Requires a Qualified Rigger
Two scenarios trigger the requirement under federal construction standards.
The first is crane assembly and disassembly. All rigging performed during those operations must be done by a qualified rigger.3Occupational Safety and Health Administration. 29 CFR 1926.1404 – Assembly/Disassembly General Requirements
The second is any lift in which workers are in the fall zone while hooking, unhooking, or guiding a load, or making the initial connection of a load to a structure. When that condition exists, three requirements apply together: materials must be rigged to prevent unintentional displacement, hooks must have self-closing latches, and the load must be rigged by a qualified rigger.4eCFR. 29 CFR 1926.1425 – Keeping Clear of the Load
Outside those two triggers, rigging still has to be done safely, but the specific “qualified rigger” mandate is what OSHA will look for during those operations.
Qualified Person vs. Competent Person
OSHA uses two labels that sound similar and carry different weight. A qualified person has demonstrated technical problem-solving ability through credentials or experience. A competent person is one who can identify existing and predictable hazards in the work environment and has authorization to take prompt corrective action to eliminate them.1Occupational Safety and Health Administration. 29 CFR 1926.32 – Definitions
Some tasks call for both. Crane assembly and disassembly must be directed by a person who meets the criteria for both a competent and a qualified person, or by a competent person assisted by a qualified person.3Occupational Safety and Health Administration. 29 CFR 1926.1404 – Assembly/Disassembly General Requirements Daily sling inspections have to be performed by a competent person the employer designates, who may or may not also be doing the rigging.
What a Qualified Rigger Actually Does
Assessing the Load and Planning the Lift
Before anything leaves the ground, the rigger estimates the load’s weight and identifies its center of gravity. Those two numbers govern everything else. Get the center of gravity wrong and the load shifts or tips once airborne, overloading one side of the rigging or swinging the load into workers and structures. The rigger also has to account for environmental factors like wind and for overhead obstructions along the planned path.
From that assessment, the rigger selects the right hardware: the type and capacity of slings, shackles, and hooks. Undersized gear is the obvious hazard. Oversized gear brings its own problems, including harder load control and a false sense of safety margin.
Inspecting the Rigging
Every sling and its fastenings must be inspected for damage each day before use, with additional checks during use when service conditions warrant. Any sling found damaged or defective is removed from service immediately.5Occupational Safety and Health Administration. 29 CFR 1926.251 – Rigging Equipment for Material Handling Wire rope develops broken wires and kinks. Synthetic slings degrade from UV exposure and chemical contact. Alloy chain links stretch under repeated loading. Skipping the inspection is not a paperwork failure; it is the moment a lift becomes dangerous.
Rigging and Running the Lift
The rigger attaches the load using the appropriate hitch, padding or protecting slings wherever they contact sharp edges on the load, since sharp edges cut through slings faster than most people expect.5Occupational Safety and Health Administration. 29 CFR 1926.251 – Rigging Equipment for Material Handling
During the lift, the rigger coordinates with the crane operator using the standardized hand signals in federal regulations, covering hoist, lower, swing, stop, emergency stop, boom movements, and travel.6Occupational Safety and Health Administration. 29 CFR Part 1926 Subpart CC Appendix A – Standard Hand Signals When the operator cannot see the load or the landing area, a designated signal person is required on site to relay directions.7Occupational Safety and Health Administration. 29 CFR 1926.1419 – Signals General Requirements Anyone on site who sees a safety problem can give the emergency stop signal, and work halts until the issue is resolved.
How to Become a Qualified Rigger
There is no single mandatory path. OSHA does not require certification from any particular organization, and employers are allowed to qualify riggers through their own internal evaluation. Most employers still look for a mix of formal training, hands-on experience, and third-party certification, because it simplifies the documentation burden and gives them an objective baseline to point to if OSHA asks how they made the determination.2Occupational Safety and Health Administration. Subpart CC – Cranes and Derricks in Construction: Qualified Rigger
Training programs typically cover rigging principles, load dynamics, hardware ratings, hitch types, and OSHA standards, paired with supervised hands-on work across different load types and lift configurations.
NCCCO Certification
The most widely recognized third-party credential comes from the National Commission for the Certification of Crane Operators (NCCCO), which offers two rigger levels. To sit for either exam, candidates must be at least 18 years old, comply with the organization’s substance abuse policy and code of ethics, and pass both a written and a practical examination.8NCCCO. CCO Rigger Candidate Handbook
Level I covers straightforward, repetitive rigging tasks where load weight, center of gravity, and rigging configuration are already known or provided. A Level I rigger inspects rigging before use, attaches basic hitch configurations, and recognizes common hazards.
Level II builds on Level I and adds the ability to estimate weight and center of gravity when calculations are needed, identify lift points, select rigging based on loading, and account for load dynamics. Level II riggers are expected to work without direct supervision on complex lifts.
Candidates who pass one exam have 12 months to pass the other. A rigger already holding Level I can move up to Level II at any time by passing the Level II written and practical exams.8NCCCO. CCO Rigger Candidate Handbook
Recertification
NCCCO rigger certifications are valid for five years. All recertification requirements must be completed during the 12 months before the expiration date. Recertification requires only a written exam, not a practical one, and passing the Level II written exam maintains both levels for a rigger who holds both.8NCCCO. CCO Rigger Candidate Handbook
There is no grace period. Let the certification lapse and the abbreviated route is gone; you retake both the full written and practical exams as if certifying for the first time.
The Employer Makes the Final Call
The employer carries the legal obligation to determine whether each rigger is qualified for the specific tasks on a given project. That assessment has to account for the nature of the load, the lift, and the equipment, matched against the individual’s knowledge and experience. A blanket “qualified for all rigging” designation does not meet the standard.2Occupational Safety and Health Administration. Subpart CC – Cranes and Derricks in Construction: Qualified Rigger
OSHA does not require the employer to use any third-party body. Internal evaluation is permitted. But if an accident happens and OSHA investigates, the employer has to show how the qualification decision was made. Records of training completed, certifications held, types of loads the rigger has worked with, and any internal assessments give the employer something to hand over. For the rigging equipment itself, federal standards require that proof-test certificates for certain sling types be kept and made available for inspection.9Occupational Safety and Health Administration. 29 CFR 1910.184 – Slings
For a rigger looking to build a career, the practical takeaway is that certification alone will not carry you. Employers hire and assign work based on the mix of your credential, your documented experience with the kinds of loads on their projects, and their own confidence that you can solve the problems a lift throws at you.
