It provides both audible and visual warning signals to alert the operator and attendant ground personnel when the boom comes within proximity of an energized high-voltage power line. SIGALARM is a solid-state electronic safety system used for detecting the electrostatic field of any AC power line. "And all truck personnel must be trained and periodically re-trained on the proper procedures to follow should they find themselves in potentially dangerous electrical circumstances. Proponents of ENG truck safety insist that such accidents are preventable by using safety devices, such as D-TEC and SIGALARM, which activate audio and visual alarms when they detect electrical danger.ĭeveloped by Will-Burt Co., the D-TEC Mast Monitor provides AC field detection, object sonar detection, tilt sensor, above the mast illumination and an anticollision system that automatically stops mast extension for protection from overhead hazards.īut just as seatbelts can only save lives if they're worn properly, "It's imperative that truck crews be trained to understand and respect the truck's safety systems," says Steven Pinkley, sales manager for Will-Burt in Orrville, Ohio. When the mast hits a power line, people on or around the truck can suffer severe electrical burns when they touch the truck, pavement or any other surface that becomes electrified. ![]() This fact has been borne out by a slew of horrendous electrical accidents, which resulted in the untimely death or lifelong injuries suffered by truck personnel.Įlectrical accidents occur when the truck's mast-which can raise an antenna as much as 56 feet from the truck roof for line-of-sight transmission-is elevated in close proximity to power lines. ![]() ENG truck makers say safety alarms must be combined with trainingĮNG truck safety is not just a good idea it's a matter of life and death. ![]()
