It is critical that the 21st-century rigger acquires the technical skills required to prevent damaged or overloaded equipment. In the worst cases, the rigger with poor training is a threat to the safety of the show. Most professional riggers learn the physical skills they need on the job site using the time-tested methods of the master/apprentice relationship. However, the technical skills of the job are better taught in the classroom environment.
