If the lift is to be out of use for a long period, disconnect the energy supplies, empty the
tank(s) containing operating liquids and protect any parts which might be damaged by dust.
If the lift is to be decommissioned, it must be made unusable by removing the control
unit components (the hydraulic pump and electric motor) from the control unit.
All parts which might be sources of danger must be rendered harmless.
Assess the lift’s category in relation to waste disposal.
Scrap as metal or electronic waste, consigning the various parts of the lift to the appropri-
ate collection centres. If the lift is classied as special waste, dismantle it and subdivide
its parts by type, then dispose of them as required by law.
