    * effective communication will be maintained between the equipment operator and the demolition supervisor while the equipment is operating
    * debris is progressively removed from each floor
    * buffers are used to prevent the plant from falling over the edge where plant is used
      to push/tip materials into a nominated areas, and
    * guarding, hoarding and/or exclusion zones are used to protect persons against the risk
      of being struck by falling debris and materials.
Load shifting equipment should, so far as is reasonably practicable, be located on a beam.
Skid steer loaders using a breaker may not be appropriate on suspended floors with their
limited reach.

It is important to consider the load created when large or multiple pieces of plant are used
for this purpose so as to ensure that any partially demolished structure can support the loads. For example, the use of an excavator with a hydraulic rock breaker or pulverising attachment
to break up walls and floors while other load shifting equipment is used to shift the debris on
a suspended floor will result in a higher load. Because of the weight of the plant, the vibration caused by its operation and the build-up of debris, careful design and planning is needed
to prevent a premature collapse of the structure.

Demolition of walls
When mobile plant (for example an excavator with hydraulic rock breaker) is used to demolish walls, at least 900 mm of the wall being demolished should be left intact above the floor level to provide a protective barrier at the perimeter of the building and around all lift wells, stair wells, light wells and any other places where persons or objects could fall. The remaining wall can later be safely demolished from the floor below. All remaining sections of walls should be identified and highlighted as buffers for edge protection.

Guarding, hoarding and/or the exclusion zones should be used to protect workers and/or the public against the risk of being struck by falling debris and materials.

Walls should not be laterally loaded by accumulated rubble or debris, to the extent that they are
in danger of collapse.

Using plant and attachments
All plant attachments should be pinned and secured as per manufacturer's requirements.
The plant fittings used in demolition should be designed and fit for purpose. To avoid damaging the equipment itself and to prevent the risk of plant overturning, equipment should not be overloaded.

When plant is used to demolish vertical features such as columns or walls, the columns or walls should
