Abstract
Disclosed is a machinery operator protection system and method, which inhibits the use of machinery unless the operator of the machinery is properly secured with a lanyard and/or body harness to the machinery. The disclosed system includes a lanyard connection detector for detecting proper attachment of at least one lanyard to a machinery operator and a lanyard interlock control for controlling a switch to selectively enable activation of the machinery when the lanyard connection detector indicates that the operator is properly attached to the machinery with the lanyard. The disclosed method includes the steps of: detecting when at least one safety lanyard is properly attached to a between a machinery operator and a piece of machinery; and inhibiting operation of the machinery unless proper operator safety lanyard attachment is detected. Optionally, the method may also include providing an audible or visual warning alarm to advise the machinery operator if he or she attempts to use the machinery without proper safety lanyard attachment.
