Workers on foot around excavators, loaders and trucks are at serious risk. Here is how to reduce it.

Why blind spots kill
Excavators, loaders, dump trucks and rollers have large areas the operator cannot see. Workers on foot walk into those zones every day, often assuming the operator knows they are there. Struck-by and caught-between incidents with equipment are among the most serious on construction sites.
Know the blind spots
Train crews on where each machine's blind spots are. A walk-around with the operator in the seat shows how little can be seen behind and beside the machine.

Eye contact rule
Never approach a running machine until the operator sees you and signals. If you can't see the operator's eyes, assume they can't see you.
Swing radius
Barricade the swing radius of excavators and cranes. Nobody stands inside while the machine is working.
Spotters
Use trained spotters for backing and tight areas, with agreed hand signals and radios when needed.
Alarms and cameras
Backup alarms, cameras and proximity sensors help but don't replace procedures.
Site layout
Separate pedestrian walkways from equipment routes. One-way traffic for trucks reduces backing.
High visibility
High-visibility clothing helps operators see workers, especially at dawn, dusk and in dust.
Toolbox talk
"Today the excavator is loading trucks on the north side. Walk the marked path, never cut behind the trucks and wait for the operator's signal."
Common mistakes
Shortcuts behind backing trucks, spotters standing in blind spots and assuming alarms are enough.
Where to start
Mark equipment zones and walkways on the site plan this week, and do a blind-spot walk-around with every crew.
Know your numbers
Track near misses involving equipment and people. Each one shows where the layout or procedures need adjusting.

Frequently asked questions
How can workers stay safe around heavy equipment?
Stay out of blind spots and swing radius, make eye contact with the operator before approaching, use spotters for backing and keep foot traffic separated from equipment routes.
