the workbox is fully enclosed
    * workers remain within the workbox while they are being lifted or suspended
    * workers do not enter or leave the workbox when it is suspended (except in an emergency)
    * the crane is fitted with the means to safely lower it in an emergency or a power supply failure
    * the crane is suitably stabilised at all times while the workbox is used
    * the crane has 'drive up' and 'drive-down' controls on both the hoisting and luffing motions
      and those controls are used. No declutching allowing free fall is to be used while a workbox
      is in use
    * an effective means of communication between any person in the workbox and the operator
      is provided
    * the crane is fitted with a safety hook and moused (lashed) accordingly
    * the operator remains at the controls of the crane at all times.
For specifications for the use of crane workboxes refer to AS 2550.1 Cranes, Hoists and Winches—Safe Use—General Requirements.
Forklifts with a work box
A workbox fitted to a forklift must be securely attached to the forklift carriage and engineer-designed and constructed in accordance with AS 2359 Powered Industrial Trucks (see Figure 12).

Safety considerations include that:

    * people are not raised on the tynes of forklift trucks or the pallet
    * no other device (for example, ladder or pallets) is used to gain additional height (see Figures 13 and 14)
    * the safety gate is self-locking and kept shut when in the elevated position.

Figure 12: An example of an engineer-designed workbox with safety harness and lanyard assembly, correctly positioned on the forklift tynes.

Figure 13: Using a forklift as a working platform or to gain extra height by standing
on the tynes or a pallet is an unacceptable practice.

Building maintenance units
Designers of buildings should consider the methods by which maintenance, repairs or cleaning
will be undertaken on buildings or structures.
A building maintenance unit is a power-operated suspended working platform that is fixed permanently to a building or structure. It is used for access for building maintenance or window cleaning (see Figure 15).

Figure 15: An example of a building maintenance unit with safety harness and restraint line.

Safety considerations include that:

    * the platform has sufficient, clearly designated safety harness anchorage points designed
      to withstand the forces caused by a fall of any person located anywhere on the platform
    * the units are designed in accordance with AS 1418.13 Cranes (including Hoists and Winches) —Building Maintenance Units and operated by competent persons in accordance with AS 2550.13 Cranes—Safe Use—Building Maintenance Units.
