is not demolished should be strong enough to remain safely in position,
or should be guyed or otherwise supported to ensure that it will be stable in any adverse
weather conditions.

Framework members should be lowered in a controlled manner. Tag lines should be used
on loads where necessary to control the load.

5.2 Mechanical demolition
Mechanical demolition involves the use of powered mobile plant, such as excavators, cranes, loaders and bulldozers. There may be a mix of hand and mechanical demolition methods applied.
All powered mobile plant used for demolition work must be fitted with a suitable combination
of operator protective devices.
Operator protective structures should be designed to the appropriate standard that eliminates
or minimises the risk, so far as is reasonably practicable, of operator injury due to:
    * roll over and consequent cabin impact damage
    * objects falling on or over the cabin
    * objects penetrating the cabin, and
    * hazardous noise.
Demolition should be planned to be systematic and sequential. That is, a structure should generally be demolished in the reverse order to which it was constructed.

Working on suspended floors
Suspended floors and their supporting members should not be loaded by workers, plant, falling
or accumulated debris/materials to the extent that there is excessive deflection, permanent deformation or danger of collapse. If water is used, the increased weight of the watered debris should be taken into account.
If powered mobile plant will be operated on a suspended floor, the demolition contractor should ensure that a competent person (for example a structural engineer) verifies and documents:
    * the type, size, weight and usage of any specified plant
    * that the floor is capable of sustaining the static and live loads of the plant (including attachments) and demolished materials, without excessive deformation or collapse, either
          + without additional support from below, or
          + with specified propping to be applied from below so that the loads carried do not exceed their manufacturer's specified rating.
Any powered mobile plant used in demolition work should be moved between suspended floor slabs by hoist equipment or an appropriately fabricated ramp.
If load shifting equipment is to be used on suspended floors as part of the demolition work,
a notification must be made to the regulator (see section 3.1 of this Code).
When using powered mobile plant on suspended floors, the person conducting the business
or undertaking should review the demolition SWMS to confirm that:
    * where plant has been specified in the SWMS, another piece of plant of the same type
      and usage may be substituted for it provided that the substituted equipment is neither larger nor heavier than the specified equipment
    * effective communication will be maintained between the equipment
