There is a wide range in the size, location and complexity of underground mines in Western Australia and, consequently, varying degrees of risk associated with these operations. However, there is the potential in all underground mines for an irrespirable atmosphere to be generated as a result of fire, outburst of toxic gases, or concentration of diesel emissions in poorly ventilated headings.

Since oxygen is vital for life, access to breathable air is critical and the bulk of controls must always be aimed at preventing the creation of an irrespirable atmosphere. However, until the sources of this hazard can be eliminated, a means of protecting persons from exposure must be provided.

This guideline provides information on the management and use of refuge chambers designed to protect people from exposure to irrespirable atmospheres underground during an emergency. Click here to download the guideline.
