Currently, I am dealing with a particular operator who thinks it is fine to navigate tight areas with the forks 10+ feet in the air with a load. Trying to find a regulation that says you should not do that.

Our own internal and external training we have received for driving forklifts says we should not travel at more than 8 inches.

Osha states you should travel at a safe height and that height is 4 to 8 inches but doesn't actually state a regulation.

Any help would be appreciated.
