Taking Shelter Safely

WHEN THE BUSHFIRE EMERGENCY MESSAGE IS 
“It Is Too Late To Leave, You Should Take Shelter And Stay Indoors” 
WHAT SHOULD YOU ACTUALLY DO?

IF YOU CANNOT SHELTER IN A BUILDING
* Shelter behind a wall, beside a large bare-ground, fire resistant tree; in nor beside a car; in a dam (if no vegetation is near either) or crouch beneath a pure wool blanket on a bare or already burnt area.


IF YOU CAN SHELTER IN A BUILDING
BEFORE YOU GO INSIDE:
* Shut off gas and electricity at the mains.
* Put pets inside: dogs on leash, cats in covered cages.
* Take in outdoor furniture, doormats, hanging baskets, plastic pot plants.

WHEN YOU ARE INSIDE:
* Make sure all doors and windows are securely shut. 
* Turn off air conditioners; cover their internal vents.
* If windows are unshuttered, cover with pure wool blankets, heavy quality quilts, foil or wet towels. Move flammable furniture away from windows. (See Post December 1 What Renters Can Do, for ideas for emergency shutters.)
Wear protective clothing, nose mask, drink often, have pure wool blankets handy and cool off when possible
* Watch the conditions outside through a small window or peephole. When flaring shrubs have blackened it’s safe to go out again. Burning tree trunks do not generally emit killing radiant heat.


PASSIVE SHELTERERS
* Close internal doors to limit fire spread if embers enter and ignite inside.
* Stay by an exit door, in protective clothing and with blanket. 
* Do not shelter in an inner room. Not in the hallway. Not in the bath. If you shelter in ANY kind of inner room – no matter how many doors it has – you could be trapped. Embers may have ignited in ceiling space, sub-floor or wall cavities. Flaming walls or ceiling could collapse on you. Or toxic fumes from smouldering cushions or wall linings could overcome you.
* It is vital for passive shelterers to exit as soon as the potentially killing radiant heat from flames has died down. 


ACTIVE SHELTERERS
* Take hose, sprayers and ladder inside with you. 
* Fill bath & troughs with water, immerse towels, roll up and place at door gaps and window ledges. Plug keyholes with play dough, blue-tack or soap.
* Fill containers (e.g. garden sprayers) with water; put these, with dippers, mops etc, in each room.
* Watch for invading embers. Particularly in the ceiling space, through windows, gaps under doors. Quickly spray or hit with wet mop any sparks, embers or smouldering furnishings. 
* If any ignition cannot be extinguished, close the door of that room.
* Maintain easy access to an exit door. 
* Never go outside during a flame front to douse an outside ignition.


EXITING

* Exit with great care, preferably from a door that is sheltered from the wind.
* Wear protective clothing & nose cover, cover yourself with your blanket, crouch, lower your eyelids and open the door gradually.

Post-2009 research by bushfire scientists revealed that although 2/3 of Black Saturday fatalities died while sheltering in or near the house, they did not die BECAUSE they were sheltering. They died because they did not know how to shelter safely.

Safely evacuating

If you want to evacuate be aware that the proportion of evacuated homes destroyed is far higher than those with defenders. 

Reduce the possibility of loss by ember and flame-proofing your home as much as possible before you leave: tightly close all windows and doors, shield windows, remove flammable plants from against windows and flammable cladding (pull them out if need be), mow grass, clear ground beneath trees, put outdoor furniture, toys, pot plants, mats etc inside, and cut back any branches close to the house. 

When you leave, dress in protective clothing, including wide brimmed hat and strong shoes, take drinking water & pure wool blankets. 

It is safer for your precious possessions to bury those you can in the garden than to take them with you.

Forced evacuation during bushfire is illegal

Anyone Wanting To Defend Their Home From a Bushfire Threat Needs To Know This:
THE LAW SPECIFICALLY ALLOWS YOU TO STAY.

Neither police nor fire officers (at least in Victoria) have a legal right to order anyone 
to leave a threatened or burning premises if they have any monetary interest in it. 
This, of course, includes renters who own anything within the property.  
Such persons cannot legally be forced to evacuate.

 The Emergency Services Legislation 2012 and The Country Fire Authority Act 
that give police & fire officers power to order 
‘withdrawal’ from ‘land, building or premises 
that is burning or threatened by fire’
 expressly excludes  
‘any person having any pecuniary interest therein or in any goods or valuables 
whatsoever thereon.’

WHAT CAN RENTERS DO

Renters can be greatly restricted in preparing their home to be safer from a bushfire, because of not being allowed to make alterations to buildings. But there is still much you can do.

Remember, the 3 core aspects of a house vulnerable to ember entry are the subfloor area, windows, and roof space. See earlier post on this.

The SUBFLOOR area is a danger when there is a space between the ground and floorboards: especially if this part enclosed by timber gap-boards. Burning debris can be carried through this.
Metal flywire can protect both subfloor and windows. Nail it over gap-boards, and the outside of window glass. This stops burning leaves and spark entry, and hinders cracking by radiant heat.

Cover gap-boards with metal flywire. remove shrubs and flammable woodchip mulch.

WINDOWS may need stronger protection if you are in an area close to forest and subject to strong winds. Protect them from being smashed and letting in a massive ember shower by making removable shutters. Attach these on days of high fire danger, as a precaution.
Temporary Shutter Ideas:
* Make a sandwich of fibreglass/mineral-wool batts or foil, pressed between sheets of 9 mm plasterboard, 19 mm hardboard, fibre-cement, corrugated iron, steel mesh or chicken wire. Attach by screws, hooks or velcro.
* Use a strong old aluminium security door.
* A roller blind of heavy duty foil protects from radiant heat and mild impact.
* If criss-crossed with adhesive tape, glass stays intact if cracked by radiant heat.
Each of these will withstand a short burst of high fire-front heat.

 
Bamboo blinds catch embers and can lead fire into the roof space.

The ROOF-CEILING SPACE is vital. It needs a thorough preparatory clean out, and careful watch for ember entry during a threat. This can be difficult to achieve when a rent house does not have any inspection trapdoor. Explain to your landlady or agent the dire potential for house destruction from this area and the great protection to their asset by installing an inspection trapdoor. 

GOOD GARDEN MANAGEMENT is usually possible. It will reduce potential radiant heat. Slash, mow, rake, prune, tidy. Replace wood chip mulch with compost, earth or pebbles. Move woodheaps and rubbish away from house and put under cover.


YOUR PRECIOUS POSSESSIONS can be left with a friend in the suburbs, put in storage, a hole in the ground. Copy computer files to an external hard drive or high-GB memory stick. 

For YOUR PERSONAL SAFETY, whether defending or evacuating, wear protective clothing and have a pure wool blanket.

Note that not even renters can legally be forced to evacuate. In Victoria, at least, if people have any monetary interest in a property or its contents, neither police nor fire officers have a legal right to order anyone to leave.

Please 'Like'my Facebook page, ‘BUSHFIRE SAFETY AWARENESS’

Stay and Defend or Leave Early'.

LINK to my talk at the Daylesford Bushfire Forum: 
"Is 'Stay & Defend or Leave Early' still relevant?" 
'Stay and Defend or Leave Early'. Is this slogan still relevant?
Is any slogan relevant? Few inform. Few are factual. Few save
lives or homes. They are seldom science-based. Often
nonsensical.












 So many slogans over the years. We’ve had:
‘People save houses. Houses save people.’
‘People and houses are safer together.’ ‘Stay in your house’
‘Stay and Defend or Leave Early’
‘Prepare, Stay and Defend or Leave Early’
‘Prepare, Act, Survive’.
And now: ‘Leave and Live’
Here are just a few of the non-factual, non-sensical new
mini-mantras spawned by the ‘Leave and Live’ slogan.
Far from raising consciousness, they increase ignorance and compound confusion. 
They contradict science, obscure facts, and immortalize errors.
