Identify confined space
Assessment tool
Version 1.0
Issue Date: April 2024
This unit was developed for Defence workers involved in the identification of confined spaces as a workplace responsibility, but is applicable to all individuals who work in this field.
Typically, these individuals must demonstrate the ability to work independently or as part of a team under indirect supervision. They must be able to use discretion and judgement and take responsibility for the quality of their outputs.
All activities are carried out in accordance with relevant legislation, organisational policies and procedures.
This unit covers the competency required to identify actual or potential confined spaces prior to entering a confined space for work purposes.
The unit includes recognising actual and potential confined spaces in one’s work environment and understanding the broad limitations they impose on work practices.
It also covers identifying potential work health and safety (WHS) concerns and seeking further advice and/or applying appropriate/relevant procedures when dealing with WHS issues.
In the context of this unit, a confined space is any compartment or area that has one of the following characteristics:
limited opening for access
no escape route or very restricted means of escape
limited natural ventilation
atmosphere containing more than 23.5% or less than 19.5% oxygen
and has the capability of accumulating a toxic, flammable or explosive atmosphere, or of being flooded.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication. In a Defence context, this means that there is no civilian need to hold this unit in order to meet licensing, legislative, regulatory or certification requirements.
