Communicate and stay in visual contact with the driver as much as possible.
Be sure the truck bed is down when opening the end gate.
Once the end gate is open, step to the left/driver side of the vehicle where you are visible to the driver in their mirror; this will also prevent injuries if there is a foreign object in the truck which may fall and hit you.
Never hoist the bed slowly to initiate grain flow into the pit.
Remain at the side of the vehicle while the grain is unloading.
Advise employees of potential foreign objects in the grain that could cause serious injury to workers or equipment.
