Intrusion warning improves workzone safety

Transpo Industries launched a unique concept in work zone intrusion protection last year. The SonoBlaster impact-activated safety device warns both roadway workers and errant vehicles simultaneously. When impacted, the unit's built-in CO2-powered horn blasts loudly (125 dB) for 15 seconds, signalling crews that their work zone has been violated.

Transpo Industries launched a unique concept in work zone intrusion protection last year.

The SonoBlaster impact-activated safety device warns both roadway workers and errant vehicles simultaneously. When impacted, the unit's built-in CO2-powered horn blasts loudly (125 dB) for 15 seconds, signalling crews that their work zone has been violated. This provides critical reaction time to move out of harm's way. The company says there are also resultant safety benefits for the driver, who may be able to take evasive action.

 Since its launch, Transpo says that as a result of customer feedback from deployments in over 27 US states as well as seven different countries, a stackable cone bracket has been added to the device so the Sonoblaster can remain mounted and ready to use on a work truck.
