For those who have already mastered basic climbing skills, aerial lift operation, and cutting techniques, The Art and Science of Practical Rigging DVD series and accompanying book provide advanced training in equipment and ropes, rigging knots, limb removal, rigging techniques and principles, and top removal. The DVD series is hosted by Ken Palmer and Rip Tompkins and consists of eight lessons as described below. The supplemental book, written by Sharon Lilly and the late Peter Donzelli, includes plenty of illustrations and a glossary of terms. A total of eight CEUs* toward ISA recertification may be earned by completing the tests in the book, sending them to ISA for grading, and receiving scores of 80% or greater on each.
