should:
    * remain level and plumb at all times
    * be kept well clear of powerlines, open floor edges and penetrations
    * never be accessed until all castors are locked to prevent movement
    * never be moved while anyone is on the scaffold.

Trestle scaffolds
Trestle scaffolds are generally not suitable for working at 2 metres or above. If they are used at heights greater than 2 metres, guardrailing should be used so as to prevent persons from falling off the open side or end of the work platform (see Figure 2). The system (including planks) should be assembled according to the manufacturer's specifications.
Some trestle ladder scaffolds include outriggers. Trestle ladder scaffolds are only suited to light duty tasks, such as painting and rendering.

When adjusting the height of a brick layer's trestle scaffold, make sure that only the purpose-designed pins are used. Do not use nails or pieces of reinforcing bar.
Work should only be performed between the trestles. Where a trestle scaffold is more than one bay in length, heavy loads should be placed directly over the trestles.

Scaffolding checklist

Control measures include the following:
          If scaffolding is to be erected from which a person or object could fall more than 4 metres,
  the scaffold must be erected, altered and dismantled by a licensed scaffolder
          An unlicensed person must not alter scaffolding without authority from a competent person
          Prefabricated scaffolds must be of the same type and not mixed components, unless the mixing of components has been approved by the manufacturer. AS/NZS 4576 sets out the assurances that are needed before the components of different prefabricated scaffolding systems can be mixed in a scaffold. Unauthorised mixing of components from different manufacturers has resulted in scaffold incompatibilities and failures, posing significant risks
  to persons using the scaffolding
          Mobile tower frame scaffolds can be used to provide safe working platforms
          Scaffolding that is incomplete and left unattended should have danger tags and warning signs attached at appropriate locations to prevent use
          Scaffolding exceeding a deck height of 4 metres must be inspected and tagged by a competent person before use, after any alteration or repair, and at intervals not greater than
  30 days
          Only a licensed person or a trainee under direct supervision of a licensed person may modify the height of a scaffold exceeding a deck height of 4 metres
          Additional inspections must be carried out by a competent person following an occurrence that may affect the stability such as impact from mobile plant or a severe storm
          Safe access
