SonoBlaster® Dual Alert™ Work Zone Intrusion Alarm SonoBlaster® is an impact-activated safety device that warns roadway workers and errant vehicle drivers simultaneously to help prevent crashes and injuries in our nation's roadway work zones. The NCHRP 350 accepted SonoBlaster® mounts on typical work zone barricades, cones, drums, delineators, A-frames and other barriers. Upon impact of an errant vehicle, the SonoBlaster's built-in CO2 powered horn blasts at 125 dB to signal workers that their protective zone has been violated, giving them critical reaction time to move out of harms way. 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. Distracted drivers are a major cause of work zone crashes. Often only a soft plastic cone is all that separates workers from danger. The number of people killed per year in motor vehicle crashes has risen to an average of 1,020 fatalities with 53,000 annual injuries.

Many work zone crashes occur when cars and trucks silently drift into roadwork zones, collapsing safety barriers without making enough noise to alert workers of oncoming danger. Work Zone Use The SonoBlaster® unit is cocked using a simple keychain tool. The unit is then placed on the roadway while in "safe" mode. The control knob is then rotated from "safe" to "ready" position. The unit is then "armed" and ready to protect the work zone.Work zone injuries involving workers harmed by their own equipment is a growing problem. SonoBlaster® audibly pinpoints the source of danger by warning workers when heavy equipment enters their "safe" area. |
