Demolition Work

Hazard, Risk and Remedy information herein adapted from Safe Work Australia material.

Work connected with the demolition of a structure 1 is classified as ‘construction work’ under the Work, Health and Safety Regulations 2011 (WHS Regulations) therefore regulatory construction requirements must be followed.

Demolition work that’s notifiable under the WHS Regulations refers to structures that are at least six metres in height and is defined as work to demolish or dismantle a structure or part of a structure that is load-bearing or otherwise related to the physical integrity of the structure 2. Demolition work involving load-shifting machinery on a suspended floor or involving explosives is also notifiable.

The demolition of an element of a structure that is load-bearing or otherwise related to the physical integrity of the structure is also ‘high risk construction work’ which comes with additional responsibilities under the WHS Regulations such as the preparation of safe work methods statements (SWMS) prior to work taking place.


Numerous risks exist within demolition work which must be controlled- these include but aren’t limited to; unplanned structure collapse, falls from one level to another, being struck by falling objects, interruption or damage to essential services such as gas, water, sewerage, telecommunications, electricity, chemicals, fuel and refrigerant in pipes or lines, injury due to hazardous chemicals, hearing and property damage.


A targeted risk management process following an approved code of practice in conjunction with legal consultation to best align the nature of demolition work with regulatory obligations is the best method of ensuring risks are controlled for properly. Numerous factors should be considered when assessing risks involving demolition work which include but aren’t limited to;

  • The structure to be demolished and its structural integrity
  • Method and sequencing of demolition
  • Scheduling of work
  • Workplace layout and fall hazard identification
  • Plant and equipment used as well as competency of workers involved
  • Exposure hazard identification (Eg noise and UV)
  • Quantity of people involved
  • Weather and environmental conditions
