This unit of competency involves the skills and knowledge required to undertake rescues in confined spaces as a member of a single organisation or team involving multiple organisations.
A confined space is determined by the hazards associated with a set of specific circumstances and not just because work is performed in a small space. A confined space means an enclosed or partially enclosed space that
- is not designed or intended primarily to be occupied by a person, and
- is, or is designed or intended to be, at normal atmospheric pressure while any person is in the space, and
- is, or is likely to 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, or harmful concentrations of any airborne contaminants, or engulfment.
The unit is applicable to a range of confined space rescue situations undertaken by personnel from the emergency services, volunteer organisations and/or organisations where confined space work is performed. Permits may be required to perform work in a confined space in various jurisdictions.
