Work Health and Safety (Confined Spaces) Code of Practice 2011 - Australian Capital Territory


You may be required to comply with this code if you intend to operate a business where your employees are required to work in confined spaces. For the purpose of compliance with this code, a confined space is determined by the hazards associated with a set of specific circumstances.

A confined space means an enclosed or partially enclosed space that is not designed or intended primarily to be occupied by a person, and could be a risk to health and safety from an atmosphere that does not have a safe oxygen level or contaminants, including:

  • Airborne gases, vapours and dusts, that may cause injury from fire or explosion;
  • Harmful concentrations of any airborne contaminants; or
  • Engulfment.

Trenches are not considered confined spaces based on the risk of structural collapse alone, but will be confined spaces if they potentially contain concentrations of airborne contaminants that may cause impairment, loss of consciousness or asphyxiation. Please consult the Contact Officer for more information and to ascertain the level of compliance (if any) that may be required.
