1USING TIMBER IN BUSHFIRE PRONE AREAS
Introduction
For the residents of Australia, bushy fire is a common thing and bushfires are very
frequent in Australia due to hot and dry climate in the months of summer. Every year such
bushfires harms the government property and harms the common people of the area in many
ways and along with it such fires increase the carbon content in the air and pollute the
environment heavily (Smith 2013). It is seen that major fire storms affects heavily and becomes
the reason behind many losses of lives and damage of domestic and government property year.
Sometimes the losses are so destructive that people give names the day when such things happen
like a black Tuesday or Ash Thursday. According to statistics in the year of 2009, a bushfire took
lives of 172 individuals and damaged property over 3 million dollars (Cavallo and Ireland 2014).
Due to massive bushfires in various areas of Australia, each year massive damages are done to
the public and government property, as well as to the wild animals and to the lives of many
individuals. Due to these kinds of devastating bushfires many a time’s crops get burnt and that
increases the prices of the grains in the market (Whittaker, Handmer and Mercer 2012). The
purpose of this report is to highlight that whether the usage of timbers are good or bad near
bushfire prone areas and how strategically people can use timber in buildings near bushfire prone
areas of Australia.
Categories of bushfire
In Australia, the term bushfire originated from ‘the bush’ meaning relatively sparsely
inhabited areas of the land. In Australia people call it bushfire when the fire is uncontrolled and
nonstructural that burns the grassy or forest areas of the land and in Australia two main types of
bushfires are seen.

Mountain fire
The fires in the hilly zones of Australia are generally known as mountainous fire and this
occurs especially in the dense forest areas of the nation (Bradstock, Williams and Gill 2012).
Mountainous fires are seen in places where the land is less accessible for the individuals and not
good for agricultural purposes. In most cases, the steep terrain allows the fire to spread in an
uncontrolled way and makes it very hard to stop using other forces by forest department (Smith
2013).
Flat fire
The bushfires that take place in flat grassy lands are generally known as flat fire. These
types of fires can move freely triggered by uncontrolled wind. In most cases these fires do not
pose many threats as these types of fires are easily controllable and cause lesser harms to life and
property (King et al. 2013).
Bushfire prone zones
In Australia there are some states where the chances of bushfires are generally very high
and in most cases uncontrollable bushfires are seen in those cases. States like Victoria, New
South Wales, Queensland and South Australia are known as bushfire prone zones.

Bushfire threat
If any people reside anywhere in Australia, he or she would definitely be familiar with
the term bushfire. Extremely dry and warm weather at summertime leads to extensive bushfire in
places of Australia (Whittaker, Handmer and Mercer 2012). Many a times, the bushfire prone
areas are densely populated and whenever a densely populated area gets burnt down to ashes,
men rebuild the area and they try to build the place in a way so that the next time fire does not
spread in an uncontrolled manner. One of the most important factors is that people should know
that they have to erect buildings in bushfire prone zones in a way so that the building does not
catch fire easily (Mannakkara, Wilkinson and Potangaroa 2014). It is not an issue that people
cannot use traditional building materials erecting buildings near the bushfire prone zones like
timber window or door frames. Individuals can use timber and wood products which were tasted
to meet the beaming heat and flame contact requirements of the Australian standard AS 1530.
For an example, Stegbar has a variety of timber windows and doors which are being tasted for

the safety reasons and those goods satisfied the Australian Standards to meet the requirements
for bushfire attack level (Macindoe and Leonard 2012).
Australian Standard AS 3959
AS 3959 divides bushfire prone areas into six major bushfire attack levels based on the
severity of the building’s revelation to ember attack, radiant heat and direct contact of the flames.
The categories are provided in this section;
BAL_LOW – very low risks
BAL_ 12.5 – low risk
BAL_ 19 – moderate risk
BAL_ 29 – high risk
BAL_ 40 – very high risk
BAL_FZ – extreme risk (Flame zone)
AS 3959 covers the methodology of determining the BAL for an allotment and further
goes on to provide the construction requirements for every level of BAL including the floors,
external walls, windows, roofs and many more (Groenhart, March and Holland 2012). Meeting
the construction requirements for respective BAL classification the new buildings will meet the
requirements of the NCC. The standard focuses on providing specifications for construction
materials for each of the six BALs and further provides an alternative of using the materials of
constructions that meet the terms with the simulated fire testing provisions according to the
Australian Standards AS 1530 (Mannakkara, Wilkinson and Potangaroa 2014).

Timbers used in buildings near bushfire prone zones
There are seven major bushfire resistant timbers that can be used in the buildings which
are near to the bushfire prone zones and those are Blackbutt, Merbau, Red ironbark, Silvertop
Ash, River Redgum, Turpentine and Spotted Gum. In NSW building regulations depend from the
requirements from the Acceptable Construction Manual within the Building Code of Australia
(BCA) which is AS 3959 Construction of Buildings in the bushfire prone zones standards
(Whittaker, Handmer and Mercer 2012). While erecting the buildings the organizations need to
keep in mind the standards set by the government and in this section those are mentioned.
While building wall enclosing subfloor space, the builders have to use timber framing
that is clad with noncombustible materials like fiber cement or bushfire-resistant timbers (Dufty
2012). While building the subfloor that supports pillars, staircases people can use regular
timbers. Even building deck and joists and even decking and stair treads they can use either
regular timber or bushfire resisting timbers (Bradstock, Williams and Gill 2012). While building
the balustrades or handrails the builders must keep in mind those they should use timbers less
than 125 mm. While building the external walls the builders has to make with less than 400mm
timber and with density of 750kg/m (Fairbrother et al. 2013).
Recommendations
The builders who erect buildings near bushfire prone zones must follow the guidelines set
by the government of Australia (Whittaker, Handmer and Mercer 2012).
The builders should keep in mind that either they have to make sure that they are using
the timbers according to the guidelines set and along with that they have to landscape the

gardens of the buildings in a way so that they are able to fight the bushfire to a certain
extent (Mannakkara, Wilkinson and Potangaroa 2014).
The builders must make it sure that the gaps between the boards must be 5mm and the
spaces below the deck must be enclosed with bushfire resistant timbers and while sealing
the timbers they have to use a non-combustible seal.
The builders should keep the woodchips and the flammable shrubs away from the edge of
the timber deck (Cavallo and Ireland 2014).
Fire resistant plants and stones are very useful to prevent mild bushfires.
The builders have to keep in mind that in the buildings there must be ample source of
water that could be used to fight the bushfire (Whittaker, Handmer and Mercer 2012).
The builders must buy moisture and decay resistant timbers for building decks.
The builders must stock domestic or imported certified hardwoods for erecting buildings
(Dufty 2012).
Conclusion
Thus to conclude, it can be said that the builders must keep in mind that if they start
erecting buildings they have to use building materials those are certified by the government as
per the standards set by the federal government of Australia. It is a fact that government must
deploy a department to supervise the buildings near the bushfire zone proactively in order to
prevent major damages. Lastly, awareness regarding this issue must be raised among the
common people and that would be much more effective. Thus, to summarize the journal, it can
be said that using the right building materials and making proper planning of the structures are to
be made are the main pillars of preventing the damages from the bushfires.
