Introduction
Houses, sheds and other buildings or structures that
are burnt in a bushfire can leave potential health
hazards in the remaining rubble and ash.
Hazardous household materials that may be present
after the fire include asbestos, ash from burnt treated
timbers (i.e. copper chrome arsenate or ‘CCA’),
medicines, garden or farm chemicals, other general
chemicals (e.g. cleaning products, pool chlorine
etc.), metal and other residues from burnt household
appliances as well as ash and dusts.
Before visiting your property (to recover personal items
or arrange cleanup activities), consider the following
precautions to protect your health. For safety reasons,
access should be limited to adults.
Before going on-site
- Electrical hazards may exist such as “live”
powerlines that may be down. Do not enter your
property until you are advised that it is safe to do
so (by officers from emergency services, utilities
or local council).
- Buildings and other structures may be unstable to
enter or walk over. Therefore before attempting
to recover items or start any cleanup works,
seek advice from your Council Building Section to
make sure it is safe to enter.
- Be aware that hot, smouldering coals and other
potentially hazardous materials may be hidden
under the rubble. For example, if you think
buildings on your property may contain asbestos
cement sheeting, take extra care when handling
building wreckage.
Protective clothing
- Wear sturdy footwear and heavy duty work
gloves to protect you from cuts from broken
glass, standing on sharp objects or getting burnt
by smouldering coals.
- Wear protective overalls (with long sleeves
and trousers). If convenient, wear disposable
coveralls and throw them out with the site waste
after use. Any non-disposable clothing should
be cleaned/laundered prior to reuse (including
shoes).
What about wearing a facemask?
- Ordinary paper dust masks, handkerchiefs or
bandannas do not filter out fine ash or dusts or
any asbestos fibres that may remain. Therefore
they are generally not very useful in protecting
your lungs.
- Special masks (called ‘P1’ or ‘P2’) should be worn
to filter out fine particles, including asbestos
fibres. They are available at most hardware
stores. ‘P2’ Masks filter out a slightly higher
proportion of fine particles than ‘P1’.
- Wearing a facemask can make it harder for you
to breathe normally. If you have a pre-existing
heart or lung condition seek advice from your
doctor before using one.
- It is also important to note that these types of
masks are much less effective if there is a poor
seal around the face and mouth. Men with
beards can have difficulty getting a good seal.
Handling wastes
- Building rubble should not be buried on-site,
or in nearby gullies, as hazardous materials in
the waste may contaminate surrounding land,
harming the environment and the community.
- Don’t spread ash around your property,
particularly if asbestos materials were used in
your home or other structures, or CCA-treated
timber was burnt.
- Make sure you wear protective clothing /
equipment before handling any debris, ash or
other waste.
- Moisten the ash with water to minimise dust.
Do not use high-pressure water sprays for this
purpose, as this can stir up the dust/ash.
Asbestos hazards – cleanup and disposal
- Buildings built before 1988 may contain asbestos
cement (or ‘AC’) sheeting in walls, roofs, floor
underlays, eaves, some flues or backing of some
vinyl floor tiles. These sheeting materials are
not generally a health risk unless they are cut
up, broken up or ground, when they may release
asbestos fibres.
- During a bushfire, the amount of asbestos fibres
released into the air is likely to be low.
- After a bushfire, fibres may become airborne
when excavation and cleanup works disturb the
asbestos clumps. If asbestos is likely to be
present on your property, a licensed asbestos
removalist should be engaged to do the cleanup
work. The waste must be transported in an EPAapproved
vehicle and taken to an EPA-approved
landfill for disposal.
- If you are present during cleanup works wear a‘P2’ facemask.
- If asbestos-containing material on your site is not
burnt, and limited to only a few AC sheets, wrap
it securely in two layers of heavy duty plastic
(or double bagged in two plastic bags for small
fragments) and take to a landfill, approved by
Council or Victorian EPA.
Ash from burnt CCA-treated timber – cleanup and disposal
- “CCA” stands for copper chrome arsenate, a
preservative that protects the timber from
insects. CCA-treated timber is commonly used in
pergolas, decking, cubby houses, cladding, posts,
gates, fencing and landscaping. After a fire,
the remaining ash/char contains up to 10% (by
weight) arsenic, copper and chromium.
- Young children are more likely to put things in
their mouths. Eating only a few grams can be
harmful. Animals may also lick or eat the salty
ash residue leading to poisoning. Therefore,
children, pets and other animals must be kept
away from these ash areas until cleanup is
completed.
- Ash can be double-bagged, sealed and taken
directly to your local landfill. Damaged timber
can also be disposed of to landfill. Contact your
Council for advice on local requirements or EPA
for further advice on the environmental effects of
CCA-treated timber.
