What is a confined space?
Regulation 3.82 of the Occupational Safety and Health Regulations 1996, defines a confined space as an enclosed or partially enclosed space which: • is not intended or designed primarily as a workplace; • is at atmospheric pressure during occupancy; and • has restricted means for entry and exit; and which either: • has an atmosphere containing or likely to contain potentially harmful levels of contaminant; • has or is likely to have an unsafe oxygen level; or • is of a nature or is likely to be of a nature that could contribute to a person in the space being overwhelmed by an unsafe atmosphere or contaminant. Working in confined spaces must comply with Australian Standard AS 2865. NB The size of a space is not one of the factors used to define a confined space. Therefore, there is no specified minimum or maximum size.
