(a) When using employer procedures instead of manufacturer procedures for assembly/disassembly, the employer must ensure that the procedures:

1. (1) Prevent unintended dangerous movement, and prevent collapse, of any part of the equipment.
2. (2) Provide adequate support and stability of all parts of the equipment.
3. (3) Position employees involved in the assembly/disassembly operation so that their exposure to unintended movement or collapse of part or all of the equipment is minimized.
