Code of practice - Excavation

This publication is for: 
Employee / workerEmployer

This code of practice applies to all workplaces in Western Australia covered by the Occupational Safety and Health Act 1984 where excavation occurs, and to all persons with the potential for exposure to hazards resulting from excavation in those workplaces, including:

  • all areas where equipment is used to excavate; and
  • all areas where processes associated with excavation are undertaken.

The document provides practical guidance to prevent occupational injury and disease in all workplaces where excavation and associated earthworks are performed.
Excavation work may range from shallow trenching and simple foundation excavation to large and complex excavations for buildings and structures and deep sewers where the risk of serious injury is very significant.
