Seaworthy is produced by the Directorate of Navy Safety Systems in the interests of promoting

MANY sailors and contractors
undertake procedures such as
inspections, cleaning and repairs
in a confined space. Hazards asso-
ciated with working in confined
spaces can, if ignored, cause fatal
or debilitating accidents.
Typical hazards are accidental
operation of mechanical equipment;
release of harmful gases or liquids;
high ambient temperatures; expo-
sure to asphyxiating, toxic, corro-
sive, flammable or radioactive sub-
stances; explosions; and insufficient
oxygen to maintain life.
A confined space is an enclosed
or partially enclosed space which
is at atmospheric pressure dur-
ing occupancy and which is not
intended or designed primarily as a
place of work. The space may have
restricted means of entry or exit,
and potentially harmful levels of
contaminants or unsafe oxygen lev-
els in the atmosphere.
An unventilated compartment is
defined as any compartment that has
been closed for more than 24 hours
without thorough ventilation. Such
compartments are liable to contain
gases capable of forming explosive
mixtures, or other harmful mixtures.
All unventilated compartments are
to be treated as confined spaces.
Personnel must be competent to
conduct specific aspects of confined
space work. This includes super-
visors, who must be assessed and
further endorsed within each unit/
ship/establishment as a competent
confined space supervisor.
Personnel required to work
within a confined space must be
assessed and further endorsed with-
in each unit/ship/establishment as a
competent confined space worker.
Contractors undertaking physical
work must do so under their own
confined space management system,
with Defence approval.
Service personnel are prohibited
from working under the contractors
system. Contractors conducting sur-
veys or quotes can work under the
RAN confined space management
system once correctly inducted.
Under such circumstances the con-
fined space sentry and supervisor
are to be service personnel.
One of the most well recognised
and often realised hazards associ-
ated with confined spaces within
the maritime sector is toxic hazard,
a scenario for which Navy practices
and exercises regularly.
The investigation of the deaths
of three personnel on board the
emergency response and rescue ves-
sel Viking Islay in September 2007
found a worker passed out due to
insufficient oxygen while work-
ing in the vessel’s cable locker,
with two further workers passing
out while attempting rescue. All
three died of asphyxiation. The
final worker died attempting res-
cue wearing an emergency life sup-
port respiratory device (ELSRD)
equivalent, an escape apparatus not
designed to be worn while perform-
ing rescue operations.
Upon discovering an uncon-
scious person in a confined space,
you should raise the alarm, don an
ELSRD, and evacuate and secure
the compartment as you continue
to raise the alarm. Never attempt to
re-enter a compartment to rescue a
fallen shipmate or contractor until
properly dressed and given com-
mand approval. The reasons we fol-
low these procedures are obvious,
but sadly deaths still occur among
some of our seagoing counterparts.

Not enter a confined space until they have been advised
by the supervisor that a risk assessment indicates that
it is safe do so, signed onto a valid confined space entry
permit; and complied with all other pre entry requirements
eg. personal protective equipment as stated in ABR 5225.
