Qualified Rigger: A rigger who meets the criteria for a qualified person.
Qualified Person: A person who, by possession of a recognized degree, certificate, or professional standing, or who by extensive knowledge, training and experience, successfully demonstrated the ability to solve/resolve problems relating to the subject matter, the work, or the project.
In October 2010, OSHA released a FactSheet to expand upon their definition of 'qualified rigger.' Essentially, you may have many years of rigging experience, but if asked to rig an atypical load (unstable, unusually heavy, multi-crane lift, etc.) you may no longer fall under the definition of 'qualified rigger.' OSHA puts the responsibility on the employer for selecting a rigger capable of performing such rigging operations
