With the advent of every summer comes the renewed threat of bush fires. For those of us living in outer suburban or rural environments the warming weather reminds us that it is time to review our fire safety plans.
In my home state of Victoria, a place with an unfortunate bush fire history, these plans can be formulated with the local fire brigade who not only hold town meetings on fire safety but will send a representative around to your property to advise on specific things you as a home owner can do to safe guard your possessions and loved ones.
Such a plan would usually include measures like establishing a clear area away from the house, removing combustibles, cleaning leaves from guttering and planning an escape route.
You should consider whether you are capable of coping with the stress of fighting a major fire. For those of us who don’t think they are up to the task, we should plan to leave the threatened area as soon as the risk becomes apparent.
This is called the stay or go policy and on the surface it would appear to be a simple matter of common sense as a well defended home offers the safest place to avoid the life threatening danger of radiant heat which causes the majority of bushfire casualties and leaving before the fire front arrives obviously speaks for it’s self.
This policy has been in place in Victoria for many years but last summer was found wanting when an unprecedented bush fire destroyed a number of rural communities.
It is suggested by some global warming advocates that the conditions that led to Black Saturday will become more common as the world heats up. Many people are now calling for new planning measures to be put in place.
One of the most frequently asked for measures is the establishment of both community and private fire shelters. Like the cyclone cellars that many Americans living on the Great Plains have in their homes, a lot of Australians who live in homes bordering the bush are now looking at building fire bunkers to protect their loved ones. There are both pros and cons to building fire shelters and any body thinking of doing so would be wise to do plenty of research before going ahead.
At the moment there is no established building standard for bush fire shelters in this country which means those that are commercially available can vary widely in price, quality and sophistication. Years ago a shelter might have been nothing more than a hole in the ground, lined with logs and then buried under some dirt but there were many instances where these make shift bunkers were sadly inadequate.
The sophisticated shelters of today by comparison come built with fire rated steel doors and concrete and are fitted with independent air and water supplies. This standard of safety does not come cheap.
Below this standard of shelter the consumers choices start to widen and as mentioned before, with no established building standard care must be taken as to the level of safety provided by each type. For example there are a number of proprietors currently offering shipping containers and water tanks featuring various modifications that might satisfy some buyers.
Before purchasing any sort of shelter you must consider the level of threat you might reasonably face. For instance a shipping container might be able to withstand the radiant heat of a grass fire out in a paddock but be unable to withstand the intense convection heat generated by a fierce forest fire.
Regardless of the shelter debate I am certain that many of us will install shelters for our own piece of mind. In closing I would just like to advise anybody thinking about putting in a fire shelter – fire bunker, to do all their home work first and buy the best that you can afford.
