How can we keep workers safe near reversing vehicles and equipment? Along with backup alarms, we need more solutions for preventing injuries.
Struck-by incidents are a leading cause of injuries and fatalities in B.C. workplaces. From 2001 to 2018, 16 workers died when they were pinned, struck, or run over by mobile equipment or vehicles that were reversing.
According to the Occupational Health and Safety Regulation, mobile equipment needs to have an “audio warning device” if the operator can’t see immediately behind the equipment.
The most common type of audio warning device is the “beep-beep-beep” tonal alarm — the kind of alarm you hear on emergency vehicles. But in the last few years, broadband alarms (BBAs) have been making their way onto worksites. BBAs sound noticeably different (some say they sound like a bird or like broken equipment) and are more difficult to tune out.
In 2017, I wrote about a survey conducted by WorkSafeBC’s Risk Analysis Unit (RAU) exploring the effectiveness of BBAs. Recently, I followed up to find out what they learned.
“The survey showed that, overall, BBAs are effective in capturing attention and cautioning people that a vehicle is backing up,” says Heather Kahle, a human factors specialist in the RAU.
“But with reversing incidents still so prevalent, the survey findings also point to a need for more solutions — in addition to alarms.”
Elimination the best step in prevention
So what else can employers do to prevent reversing incidents?
Heather suggests turning to the hierarchy of controls as a starting point. Elimination — physically removing the hazard — is the first choice when thinking about how to reduce risk. (Visit WorkSafeBC’s Controlling risks page to learn more about the hierarchy of controls.)
Here are some examples from Heather that may help employers reduce the risk from reversing mobile equipment:
- Schedule work tasks (like surveying) when mobile equipment isn’t in use
- Give drivers feedback by installing backup camera systems inside their cabs
- Implement detection systems, such as having workers wear radio frequency identification badges (RFIDs) that provide a signal to equipment drivers when workers are in the area
