Your May 18 letter to Mr. Jim Knorpp, the Occupational Safety and Health Administration (OSHA) Area Director for Fort Worth, was forwarded to this office for response. I apologize for the delay in replying to your inquiry as to OSHA's interpretations of the terms certified and qualified as used in ANSI standards for aerial lifts.
Pole bending. Pole bending is a timed event that features a horse and one mounted rider, running a weaving or serpentine path around six poles arranged in a line.
Combined driving. Horses can race in harness, pulling a very lightweight one-person cart known as a sulky. At the other end of the spectrum, some draft horses compete in horse pulling competitions, where single or teams of horses and their drivers vie to determine who can pull the most weight for a short distance.
