1.5
Clause 6 of this Standard provides minimum requirements for initial and ongoing familiarization and upgrade training in the operation of lift trucks, including any of their attachments.

Notes:
(1) Due to the different design of vehicles classified as Class 6, non-powered high lift trucks, and personnel and burden carriers, only certain parts of Clause 6 will be relevant; however, appropriate training for these classes is to be provided to operators of said equipment.
