Home Front: Home defence and preparedness.

The folks atSimpliSafe home security, have done a lot to help everyone understand the importance of protection. This month, they're having everyone think about the subject and hear how we'd survive if we found ourselves in one of our favorite scary movies or shows. I wanted to give you all my take on what items would you utilize to protect yourself and your home in the case of a zombie apocalypse or lawless nation?"

The idea being how it's hard to find accurate survival movies, and we can all agree there is nothing worse than an incompetent character trying to survive in a film. Being such an avid survivalist myself, or at least a vocal one, I wanted to give my take on protecting my home from the most terrifying of scenarios. Bug-in-style.

So first up, lets talk scenario:
Without going too supernatural, in which a lot of options are right out, I'd like to go for a grounded, realistic and scary situation, the top of my list would sit at the 28 Days later or Dawn of the Dead style zombie apocalypse: mass casualties, civil disarray, utilities slowly winding down as infrastructure collapses, total lawlessness, and fast, savage, infectious and hungry semi-living foes.

Not a lot of lead up, maybe a couple of days at most as the situation escalated from "this just in..." news on the TV to "martial law" and then "....static ..." of the fall of civilisation. Sure it would be possible to talk about "how to best make a fort, but I've covered that kind of thing before. This situation is "hey, the world just ended, how do you make your house safer?"

Aside from providing a secure wireless security system, the folks at SimpliSafe had this cool Layered Defense presentation that made a lot of sense, in a regular world security perspective, and I thought I'd build on that:

1.  The Safe Room: safe, flashlight, mobile phone.
2.  Inside the house: TV & lamp timers, hidden valuables, obstruction under windows, heavy drapes, wireless alarm systems.
3.  Walls, Doors & Windows: Garage with multiple locks, solid reinforced doors, waring signs, security film, keyed window locks.
4.  The Grounds: security lights, gravel, outdoor lighting, prickly plants, dog.
5.  Locked gates: low level fencing, more warning signs.
6.  The neighbourhood: Know your neighbours, street lighting, neighbourhood watch.

So that's a lot of good points. Do we have a "safe room" well, given the layout of the house, the best option is probably Tactical baby's room, which has a single window facing the side of the house next to us, and no access to it elsewhere. Protection through obscurity.

More on the neighbours houses later ...

Inside the house we have a lot of things covered, blinds and locks, including sliding windows blocked with rods dropped into the rails to prevent unwanted sliding, even if unlocked. In this situation, you wouldn't want timers switching lights ON at night, but rather, OFF, to obscure your presence, even if there were still mains power.

Our grounds could do with some serious work, but the solid wall of houses on one side acting as a double protection, the biggest concerns are the bay-window facing the street.

My plan would be to barricade this inside and out, using futon-bed slats as a basis to bar it and layers of cladding to seal it up. Higher windows aren't as much of a concern, except for noise and light discipline.  Our backyard fence is a bit rickety, but can be reinforced from the inside, and materials salvaged from our shed could also assist in reinforcing it, and barricading. In the worst case, we could just fall back, and barricade the back of the house, abandoning the back-yard. If I could rig up hurricane fencing, even on the inside of the wooden slat fence, I'd be a lot happier. as its a rental, the chances of getting the fence replaced is pretty slim.

Our front yard, with its white picket fence, and big windows presents its own problems. Not high enough or strong enough to obscure the home, or repel hordes, it does offer a buffer, and allows you some visibility as to what's going on. By reinforcing and barricading the windows, again, with shed walls, and bed-slats, you could quickly rig up a hurricane and zombie resistant house-front.

We recently replaced the aging fly-wire and aluminium frame screen door, with a steel mesh and framed security door, complete with new wooden beams to fit it to, giving us a much more secure front entrance. Coupled with our Strike Plate lock, the front door is more secure now.

Here's where my plans get devious. Given the scenario laid out, our home isn't great, defensively, but my neighbors house is. Walled in by our house, and their other side neighbors, and again at the back. Walled garden at the back. Solar power, rain tanks. Roof access between their and ours (the gap is only about 1.5m).

If the world came to a horrid, zombie infested end? We'd secure our place as best we could, and make plans to move one house over. Know your neighbors. Know your neighborhood. Be well respected, appreciated and valued. Look out for each other and be ready to help when called, and you'll be welcomed in times of adversity, AND know where the best bolt-holes are.

Home Front: shipping containers

 
I've briefly covered the use of shipping containers as houses, but I wanted to go into them in a little bit more depth. About 80% of the world's containers are either 6.1m, twenty foot or 12.2m, forty foot standard length boxes of the dry freight design. These typical containers are rectangular, closed box models, with doors fitted at one end, and made of corrugated weathering steel (commonly known as CorTen).
 
Weathering steel refers to the chemical composition of these steels, allowing the steel to rust in order to form the protective coating.
 

The containers are typically lined with a plywood floor, but bare walled and ceilinged. Corrugating the sheet metal used for the sides and roof contributes significantly to the container's rigidity and stacking strength, just like in corrugated iron or in cardboard boxes.
 

 
Standard containers are 2.44 m (8') wide by 2.59 m 8'6" high, although the taller "High Cube" or "hi-cube" units measuring 2.90 m (9'6") have become very common in recent years.
 
By the end of 2013, high-cube 40 ft containers represented almost 50% of the world's maritime container fleet, according to Drewry's Container Census report.
 

 
ISO containers have castings with openings for twistlock fasteners at each of the eight corners, to allow gripping the box from above, below, or the side, and they can be stacked up to ten units high. Regional intermodal containers, such as European and U.S. domestic units however, are mainly transported by road and rail, and can frequently only be stacked up to three laden units high. Although the two ends are quite rigid, containers flex somewhat during transport.
 
Their standardised design, high strength and durability materials, makes the use of shipping containers for domestic repurposing quite appealing. They can be stacked, staggered and arranged. The corrugated steel can be welded, cut and shaped, and the heavy beams at each corner and the solid base give you the ability to completely cut away the sides to give a open-plan effect.
 

 
The rest of the stats of the containers give you an idea of their workability, as far as architectural use goes: A 40' container weighs 3,800 kg and has a capacity of 67.5 m³, and are typically rated to have a net load of 26,200 kg. That's a lot of capacity. The internal dimensions are 12.03m x 2.35m x 2.38m, and externally 12.2m x 2.44m x 2.59m.
 

Converting them into homes isn't anything new, and there are loads of resources to review plans and different configurations are widely available.
 
There is also some good advice about what NOT to do with your shipping container, namely burying them, because they are not designed to take loads on the sides or middles of the panels, rather than on their stacking corner posts.
 
There are also the issues with the containers "floating" if buried, let alone at sea, if they fall off the back of a ship, which apparently happens more often than anyone wants, but other than that, they are very versatile, and readily available, rapidly pre-fabricated units.
 

They are, however, not designed to be bulletproof, and the folks from Civil Advantage put them to the test in the following video.
 
However, if you really need that kind of thing going on, there are of course, options. However, all told, it looks like they are robust, resilient and readily available home construction alternative. I think I would really like to do this at some stage, at least a two storied construction, and in my minds eye, a horse-shoe style two-story building, which can be buttoned up securely at the ground level.
 
 
What do you think?
 
 
 
 
 
 
 

Home Front: Modscape house

I came across this interesting house design, by Modscape.com.au which piqued my interest, as I always look out for good fall-back positions, or even first-front positions. I've covered walled security for homes in the past, and walled storage facilities I've also covered my own home and why it's not all that well suited to sticking out a disaster, so it's interesting to see a purpose built place, and not all that far from myself.

The design brief of this home was to "create an airy pavilion that takes advantage of the views while providing a private haven from the busy road below". Rendered brick walls frame the home to create a protective compound which not only the provides the homeowner privacy, but ensures the home is secure. The home’s long, linear form takes advantage of the northern sun and visually connects to the bush and mountain landscape beyond.

Here is the link to the house design brief.

This modular home, in Berry, NSW,  creates a private home behind security walls for the clients who were based in my own home town of Melbourne.

All of the services are concealed from view behind the high walls, with visitors entering via a large pivoting door that penetrates the wall. They then move through a timber battened walkway where dappled light from the surrounding bushland filters through before entering into the double height entrance space. The main living zone opens out to the north-facing courtyard.

Meeting all the functional requirements of modern, sustainable design, the home has a total floor area of 465 sqm and consists of 11 modular sections with a large, open plan kitchen/living/dining area at its heart. A timber joinery core conceals services such as butler’s pantry, laundry and bathroom and houses a staircase leading to an upstairs area. It should be noted that that upstairs area is exposed and visible from the outside of the walls.

The finished palette is minimal and modest with timber, concrete and zinc used in an uncomplicated manner create a design that is humble and nondescript. All landscaping, including the pool, was also coordinated by Modscape.

FEATURES
Open plan kitchen/living/dining
2 bedrooms with joint ensuite
Guest bedroom
Upstairs "music" room
Butler’s pantry + laundry
2 car garage + workshop
Ribbon strip timber cladding
Landscaping including pool
Hydronic heating
Grid connect solar
Built to Bushfire Attack Level (BAL) 29

Looking at the plans, and the layout, including both the property selected, but also the way it sets in to the surrounding areas, offering security through obscurity, I can see the real value in having a property such as this. Putting in extra rain collection reservoirs, solar and/or wind power generation and a fuel reservoir, vegetable beds and perhaps chicken runs to set up a more self-sustainable setup, you have quite a secure (from mundane risks) and off-grid home to fall back on.

Events: Nagasaki 70 years on

What if the 1945 "Fat Man" bomb was dropped on Melbourne today?

Following on from my "Trinity Day" post a few short weeks ago, a chilling reminder. It is now 70 years ago since, on August 9th, 1945, at 11:01:47am the Fat Man bomb exploded some 500m above Nagasaki, Japan, outright killing between approximately 39,000 and 80,000 people. The blast was estimated at around 20kt, and it set fires through the mostly wood and paper construction of the city that left it devastated, even before the radiation effects began to manifest.

What if a 10kt "dirty bomb" was detonated in downtown Melbourne?

Some very clever people at Stevens Institute of Technology, namely nuclear historian Alex Wellerstein developed  “NukeMap” which allows you to overlap various atomic and nuclear events over a regular GoogleMaps view. You've seen this kind of effect with the Sea-Levels which I discussed in my Rising Sea-Levels post. The NukeMap application demonstrates the estimated (and extrapolated from actual tests) effects of these weapons on built-up areas, including "Fireball radius", "20psi Air Blast radius", "5psi Air Blast radius", Radiation Radius" and "Thermal Radiation Radius", each with a descriptor of the kinds of damages you could expect to see, and survivability of those effects.

What if the currently deployed 800kt Russian "Topol SS-25" ICBM munition was dropped on Melbourne?

It also then overlays that with estimated population density in the areas covered by the various zones, and estimates immediate fatalities, and injuries. For explosions of either sufficient size, or proximity to the ground to kick up fallout (high air-busts hit harder, and wider, but don't kick up as much fallout, it's inefficient to do so, apparently), NukeMaps will also plot prevailing winds and density of fallout.

What if the currently deployed 800kt Russian "Topol SS-25" ICBM munition was detonated in downtown Melbourne?

You can pick your location, and from a variety of historically documented devices, from the North Korean tests, Pakistani and Indianweapons, the Trinity and WW2 bombs, all the way up through the Cold War era tests and production weapons, from estimated improvised terrorist weapons to the state-irradiating Tsar Bomba weapon.

Its a very sobering tool to visualize both the destructive capacity we have been capable of for the past 80 years, but also as a reminder of how fortunate we are to have only ever had these forces brought to bare in anger only twice.

Events: Trinity Day

"Trinity Test Fireball 16ms" by Berlyn Brixner

From Wikipedia

Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army on July 16, 1945, as part of the Manhattan Project. The White Sands Proving Ground, where the test was conducted, was in the Jornada del Muerto desert about 35 miles (56 km) southeast of Socorro, New Mexico, on the Alamogordo Bombing and Gunnery Range.


This test, which was found to have a yield of 20 kilotons

"Trinity-ground-zero-men-in-crater". 

ushered the world into the era of atomic weapons. Just 4 weeks later on August 6 1945 the first atomic weapon, Little Boy was used on Hiroshima .

 The people who developed the bomb, and tested it, people like Oppenheimer , Fermi and Feynmen took bets on what the outcome of the test would be, in terms of the expected yield, with bets ranging from 0 to 45kt.

Fermi took it a step further and offered to take bets among the scientists and military present as to if the atmosphere would ignite, and if so whether it would destroy just the state, or incinerate the entire planet.

Oppenheimer was reminded of the Bhagavad Gita; quote 'Now I am become Death, the destroyer of worlds.'. George Kistiakowsky is reported to have said "Oppie, you owe me ten dollars" .

For the first time, humanity was wielding the power of the stars, and producing weapons that were capable of effecting mass destruction on a strategic, geological and generational scale.

The Trinity tests marked the beginning of the era of nuclear warfare, which thankfully we've only ever ventured into in fiction and strategic documentation. And Preppers ....
