Forums : Scissor lifts and fall protection

I thought that a scissor lift did not require a harness if the railings were up and you did not exit the lift when extended?

I know they are required for a boom lift or articulating platform?

Does anyone have the OSHA reference?

I haven't had a problem, but a customer is requiring me to wear one with my lift on Their property, unless I can prove otherwise. It's not a bog deal, but in certain situations it is a PITA.
