within which there is a risk of one or more of the

AS 2865 – 2009 does NOT apply to:

underground mining

tunnelling

abrasive blasting

spray painting

trenching

excavation work
7
ATMOSPHERIC PRESSURE DURING ENTRY

Many confined spaces are not at atmospheric
pressure when in service
p

Establishing atmospheric pressure for entry is a
control measure
8
A PLACE OF WORK

All State OH&S statutes contain a definition of a
place of work

Working in a confined space can literally make
the space a “place of work”
9
RESTRICTED MEANS OF ENTRY & EXIT

Some confined spaces have unrestricted entries
/ exits other have not
and/or

The term “restricted” is a subjective judgement

A restricted means of entry & exit may make it
difficult to access and egress and increase
emergency response times
10
ENGULFMENT (AS 2865-2009 definition)
The immersion or envelopment of a person by a solid
or liquid, (which may include grain, sugar, flour, sand,
coal, fertilizer and other substances in a powder or
granular form).

TASK-RELATED HAZARD (AS 2865-2009 definition)
In respect to a confined space means exposure to a
hazard as a consequence of the task being conducted on
or in a confined space.

Confined space task-related hazards are identified &
assessed the same as any other workplace activity.

16
RECLASSIFICATION OF A CONFINED SPACE
For a confined space to be reclassified to a non
confined space it needs to have undergone sufficient
changes in structure or usage to eliminate (without the
need for risk control measures) all possible sources of
inherent hazards that define a confined space.
