Just went thru training
I just went thru sissors lift training, and the same questions were asked.
If the lift has tie points you must use them.
If the lift don't it is grandfathered in.
If your body leaves the plain of the lift, example reaching over the side you need them.
This was a OSHA certification class.
I don't want to be strapped in a sissors lift when moving, if it gets hit or falls over I want that last chance to grab something and not have the lift drag me down with it.
A cowboy may get thrown , but they always get up and walk forward.
