In 2022/23 in the UK, moving objects (including falling ones) were the second-highest cause of workplace fatalities, beaten only by workers themselves falling from heights. Moving objects were also the third-highest cause of non-fatal workplace injuries. This goes to show just how dangerous elevated work can be, especially when it involves hand tools.
Dropped object hazard mitigation can involve measures like handrails, toeboards, netting, and exclusion zones (off-limits areas under elevated workers). None of these fully omit the hazard, though, not even exclusion zones, since fallen objects can still bounce and hit someone from a horizontal trajectory.
Safe tool tethering systems ensure that tools never drop in the first place, provided the tethering is secured properly and rated to the tool weight. Also, the materials of tool lanyards can absorb the falling tool’s momentum, thereby protecting the tool operator from the tool snapping back up.
As serious and concerning as workplace injuries and fatalities (and their litigation) rightfully are, equipment damage and time delays are business concerns too. When tools fall, they can damage other materials, become broken and require costly replacement, and force operators to spend time travelling to the ground to retrieve the tool and assess damage. Tool tethering instead turns a tool drop into a loss of a few seconds regripping it.
