fire management
Fuel management
While every effort is made to prevent fires from
starting, Victoria will always experience bushfires
from either natural or human causes. These
bushfires can threaten human life, property, assets
and, at times, the environment. One way of
protecting assets and also limiting the spread and
severity of bushfires is by strategically reducing the
‘fuel’ in our parks and forests. Fuel reduction burns,
are fires of low intensity used to remove the fine,
more flammable fuel from parts of forests and
parks. By reducing these fuels, a bushfire that
either burns into a fuel reduced area or starts in
one will have lower flame height, reduced intensity
and will spread at a slower rate, making fire fighting
easier.
The term ‘prescribed burning’ refers to the use of
fire to achieve planned land and resource
management objectives:
> fuel management: protecting life and property
from uncontrolled wildfire through the
development and implementation of strategies
for fire prevention and suppression;
> flora and fauna management: active use of
controlled fire to alter habitat structure and plant
and animal community composition to achieve
biodiversity conservation outcomes.
Prescribed burning at Anglesea
On March 1st a prescribed burn was carried out in
the Anglesea Heath in a sector bounded by
Coalmine Road, Pipeline Track and Raven Track.
At approx. 16:00, Alcoa Anglesea was informed by
Parks Victoria that the control burn had moved
beyond its nominated perimeter. An investigation
into the Coalmine Road burn indicates the cause
was a spot over approx. 200 metres ahead of the
fuel reduction burn. Embers from the planned burn
dropped outside the burn perimeter and burnt an
additional 75 hectares running parallel with Alcoa
Boundary track and extending the west boundary
towards Harrison Track South. Approx. 40
hectares of this area was identified in the current
Barwon - Otways Fire Operations Plan for planned
fuel reduction burning in the next two years.
The result is excellent protection for the Power
Station from wildfire and over the coming months
small burns will be carried out to further
consolidate the area by bringing the burn
boundary out to strategic tracks.
Conducting prescribed burns is not without risk.
However, the risks associated with fuel reduction
burning under controlled conditions are far
outweighed by the increased risk of bushfire if no
fuel reduction has occurred.
Within the community there exists a range of views
regarding the role of fire. These range from the
belief that there should be no interference to
natural fire patterns through to the belief that,
because fire is a natural part of the forest’s
ecology, it should be used freely as a management
tool. The perceptions by Australians of their
environment continue to evolve. Fire was, is, and
will remain, part of ecological Australia.

OUR ENVIRONMENT AND OUR EMPLOYEE
Welcome to Anglesea Nick - what have you been up to since
you left Pt Henry in 2006? We moved to WA in February 2006
for my role as Environmental Scientist at the Kwinana Refinery.
This role was focussed on consulting to the site departments on
environmental issues including compliance with environmental
licence and ISO14001 certification, as well as driving
improvements in environmental performance.
Your new role is in ABS - how does that relate to your
environmental background? There is a real similarity in the role
as an Environmental Scientist with that of an ABS Consultant in
that the work involves influencing people to do their work
differently to achieve improvements in performance.
What are your impressions of Anglesea and what will be
your focus first up? I’ve been working at Anglesea since just
after Easter and I’m thrilled to be working in a plant where you
can learn everyone’s name within a couple of weeks, and form
strong relationships with a large proportion of the site people.
There has been a very positive response to my role, and I’ve
encountered an attitude generally that is open to the prospect of
doing things differently. The main focus in the first couple of
months will be to try and get key activities and processes
displayed visually in order to highlight and solve problems.
...NICK BROCKMAN
