Back Up and Warning Alarms

Select the right back up alarm and warning alarm to overcome blind spots

The rear blind spot is a huge problem for commercial vehicles and machines – in fact reversing vehicles now account for a quarter of all workplace deaths. With 90% of reversing accidents occurring off-road (loading bays, lorry parks, quarry sites and warehouses) there has never been a greater necessity to carry out effective risk-assessments of vehicle reversing processes.

A back up alarm can be installed in any commercial vehicle to warn people in the vehicle’s path that it is moving backwards. Introduced in the 1970s, beeping alarms provided a vital step forward in safety, yet over time they have been shown to have several inherent issues; from their environmental impact to concerns about safety and ability to prevent accidents. There is now a much better alternative to the back up beeper with the development of white noise alarms.



Developed by Brigade, the bbs-tek® multi-frequency back up alarm uses a wide range of White Sound® frequencies. This enables the listener to instantly locate where and what direction the sound is coming from. The broadband noise also gives workers wearing hearing protection devices (HPDs) and people with hearing difficulties a better chance of detecting the alarm.

Heard Only Where it Matters

The bbs-tek® White Sound® back up alarm creates a “ssh-ssh” sound which is gentle on the ear and dissipates quickly, meaning the alarm can only be heard in the danger zone reducing the environmental impact of work sites.
