Work zone alarm protects workers

SonoBlaster is an impact-activated safety device that warns roadway workers and errant vehicle drivers simultaneously to help prevent crashes and injuries in roadway work zones. The SonoBlaster mounts on typical work zone barricades, cones, drums, delineators, A-frames and other barriers. Upon impact by an errant vehicle, the SonoBlaster's built-in CO2 powered horn blasts at 125 decibels to signal workers that their protective zone has been violated. The SonoBlaster's loud alarm can also alert distracted or drowsing drivers, allowing them to steer clear of the work zone or brake prior to reaching workers or equipment.
