HSE has published an Approved Code of Practice (ACOP) and guidance called Rider-operated lift trucks: Operator training and safe use. Approved Code of Practice and guidance.
This sets the minimum standard of basic training people should receive before they are allowed to operate certain types of lift truck - even if they only operate the equipment occasionally. It also provides detailed guidance about how they can meet this standard.
The ACOP covers stacking rider-operated lift trucks, including articulated steering trucks. 'Rider-operated' means any truck that can carry an operator and includes trucks controlled from both seated and stand-on positions.
If you employ anyone to operate a lift truck covered by the ACOP, you should make sure that operators have been trained to the standards it sets out.
The ACOP also includes some sections taken from 'Safety in working with lift trucks' (now withdrawn).
