Vehicles & Heavy Equipment Case Study
|These case studies
are part of tailgate/toolbox talks that were developed for use under
California OSHA regulations. The American Conference of Government
Industrial Hygienists (ACGIH) has adapted these talks to apply to

Killed by Backing Dump Truck
A 36-year-old construction inspector for the county died when an asphalt
dump truck backed over him.
The truck was bringing hot asphalt to a new road being constructed in
a housing project. The inspector was wearing an orange reflective vest
and hard-hat at the time of the incident. The dump truck had a back-up
alarm that was functioning properly.
The truck traveled approximately 770 feet in reverse before backing over
the inspector. The inspector had his back to the vehicle at the time.
The truck driver stated he was traveling approximately 5 to 10 miles per
hour when the incident occurred, and that he never saw the inspector.
Emergency medical personnel responded within seven minutes and pronounced
the inspector dead at the scene.
What should have
been done to prevent this accident?
Cal/OSHA investigated this accident and made the following recommendations.
- Require use of
a second person as a spotter when backing heavy equipment with blind
- Minimize the
distance heavy equipment needs to back up to gain access to the work
- Consider using
additional safety devices on heavy equipment to warn workers of a backing
vehicle and to warn drivers when someone is in their blind spot.
