Back Up and Reverse Warning Alarms

Why Back Up and Warning Alarms?

The rear blind spot is a huge problem regardless of vehicle/machine with reversing vehicles now accounting for a quarter of all workplace deaths. With 90% of reversing accidents occurring off-road (loading bays, lorry parks, quarry sites, warehouses etc.) there has never been a greater necessity to carry out effective risk-assessments of reversing processes.

Back up alarms are devices to warn anyone in a vehicle’s path that it is moving backwards. Beeping alarms were introduced to Europe in the 1970s. They provided a vital step forward in safety, yet over time they have been shown to have a number of inherent issues; specifically concerning their environmental impact, but also in terms of safety – the exact reason they were introduced in the first place. There is now a much better alternative.

Brigade bbs-tek® Alarm

Instantly Locatable Sound

bbs-tek® multi-frequency back up alarms use 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 sound also gives workers wearing hearing protection devices (HPDs) and people with hearing difficulties a better chance of hearing the alarm.

Heard Only Where it Matters

bbs-tek® White Sound® reverse alarms create a “ssh-ssh” sound which is gentle on the ear and dissipates quickly, meaning the alarm can only be heard in the danger zone.

Pioneering Back Up and Warning Alarms

Over the decades reversing beeper alarms became standard on almost every commercial vehicle. However, concerns began to be raised about their effectiveness in an urban environment or on a work site, where several alarms could sometimes sound at once, making it difficult to establish where the danger was coming from. Additionally, the piercing beeps caused by high-pitched tonal alarms generated countless complaints about noise pollution.

The answer has come in the form of Brigade’s bbs-tek® White Sound® Reversing and Warning Alarms – a revolutionary new generation of alarms that have rapidly superseded the ‘beep beep’ products of the past.
