Powerline hazards for dumptrucks
There are increasing numbers of power line contact incidents with dump trucks. With that said it is critical to know best practices around loading and unloading trucks safely.
Types of electrical hazards:
- When raising the truck box there is a risk of directly contacting an energized line which also energizes the truck and ground around the truck
- When raising the truck box near an energized line there is a risk of the electricity bridging to the truck box energizing the truck and surrounding ground
- There is potential for bringing down the truck box onto wires of any kind which can result in pulling down the poles or electrical wires onto the truck
Ways to avoid these hazards:
- When arriving onto the job site visually locate all overhead lines
- There are safe limits of approach for different voltage; know your limits
- Having a designated signaler is vital when working around overhead lines
- When possible create a designated drop zone away from all power lines
- Ensure the truck box is lowered before moving the vehicle
If your truck becomes energized:
- Remain inside the vehicle
- Call 911 and inform them of the situation
- Inform others to stay away
- Wait for help and do not exit the vehicle
The only exception to staying in the truck is if it is on fire. In this case it will be necessary to jump from the truck landing on both feet. Do not touch the truck and ground at the same time. Then shuffle both feet as close together as possible for at least 30 feet.
