Cover your webcam

Cameras  are showing up more and more on different kinds of electronics we are using; smart TVs. computers, tablets, phones, etc. Most of these will be connected to the internet and there for will be venerable for hackers. Although common sense (don’t click on certain things) and antivirus suites help, it’s certainly not a guarantee that nobody will be able to access your webcam. Even LED indicator lights from webcams can be disabled by hackers. So one sure way to stop others from watching you using your camera’s is to tape it off.

Here are some links about this subject: From the Norton website:

The Washington post did a article about this. Which is also a warning for Apple users whom thing they are invaluable to viruses.

My car kit

If you have a car it’s good to carry some additional equipment with you. Not only useful when something happens while you were traveling, but also useful when you are somewhere and need something.

There are many methods to carry emergency equipment in your car. I prefer to stick everything in all the little pockets, nooks and crannies I can find. I do have a small cooler (winter only) and toolbag in the trunk. My car is in the ‘mini’ category, so there is limited cargo space and having equipment place in something prevents it from becoming a projectile during an accident. Here is what I carry in my car:

Emergency equipment:

Emergency lighting at home

Emergency lights can be found on commercial or high occupancy buildings. Different countries have different law regarding to emergency lights. Some country’s require a combination of emergency lighting and lit emergency exit signs, while others only require lit emergency exit sign lights. Some countries want emergency exits light mounted high, while other low. In some cases the emergency exits light are always  turned on and sometimes it’s lit when the power fails.



On private residential structures, there generally are no rules for emergency lighting. The same challenges does exist when the power goes out. You need to be able to see to safely move around and in emergency's to find a way out safely. People should be aware that external lights from neighbors or streetlights will not be on, if the power interruption is not limited to your house. This means the little light from outside that allows you to see in the dark, is not there. So putting flashlights on a fixed location, might not be a great solution without any additional markings. Using commercial emergency lighting can be a bit expensive for regular consumers, there are a two options consumers can take:

- There are rechargeable flashlights  available, which will automatically turn on when the power goes out and when the light is pulled from the holder/socket. Often these lights are also equipped with an indicator/night light, so you can find them for normal use. (For example: Eton ARCBB200W DBL Blackout Buddy (USA), Olympia LED NL300 (German) or Alecto LED ATL-120W (Dutch / Belgium)). The advantage and disadvantage is that they will turn on, when they power goes out. They are usually aimed at the ceiling and the light will reflect of the ceiling and illuminate the room.


- Other options would be a flashlight with glow in the dark markings (make sure these are exposed during the daylights) or a Beta-Marker. This option does not require a power socket and does not continuously consume power (although a trickle charger does not use that much).

The flashlight with automatic turn on switch are probably the best option as a home emergency lighting. However sometimes you don't need a light when the power goes down. If you are sleeping, there is not much you can do if the powerline goes down and in most cases (in my country) the power is restored pretty quickly. So you might as well continue to sleep (a backup battery in your alarm clock is always nice) and find a light when you do need light. So choose the appropriate option for different rooms.

Tape over 9V batteries

A good tip about fire safety and batteries. Tape over or cap the terminals of batteries when they are loose!

Starting a fire with a 9 Volt battery and steel wool is a quite know trick. 9 Volt batteries are easy to short, both terminals are right next to each other. So any piece of metal can touch them and short them out.  Even if the materials shorting the terminals might not catch fire, the batteries does get extremely hot and can cause combustibles nearby to burn. So remember when tossing 9 Volt batteries in a bag of other batteries or in your junk draw, tape or cap them!


A far more detailed rapport about 9V battery issues can be found here at Richard Friedrich lab journal: http://friedrichengineering.com/web_documents/9volt%20Battery.pdf

Simple workable solutions

I have mentioned keeping things simple before, but I found a great example when this applies. The Nigerian Dr Awojobi Oluyombo makes medical devices him self, which he can repair himself and does not require any power. A great example how people adept to a situation and finds a simple low tech method to his needs:

His paper: THE TRAVAILS OF RURAL SURGERY IN NIGERIA AND THE TRIUMPH OF PRAGMATISM:
http://www.ifrs-rural.com/THE%20TRAVAILS%20OF%20RURAL%20SURGERY.pdf

Some articles by the media:

http://www.who.int/bulletin/volumes/88/5/10-040510/en/

Often I think why there no not more simple, easy serviceable equipment out there. Items should be built to last and if they break it should be easy to fix.

If you are interested in medical care in extreme environments, the book'Improvised Medicine: Providing Care in Extreme Environments', by Kenneth Iserson  is a great book.

Insulation, what to use for a emergency kit.

One of most impotent things to keep you alive are clothing and other form of insulation like a blanket of sleeping bag. Proper closing can in extreme conditions mean the difference between life and dead. In our modern world the primary role of clothing; protecting you from the environment, is of less important. There are heated cars and buildings everywhere. A lot of people cloth them self's fashionable, but not necessarily practical.

There are many article on the internet about outdoor clothing. This is a very good place to start when you are setting up clothing for your emergency preparedness. The basics are a three layer system:
- Under layer to wick away moisture from the skin
- Insulation to keep warm
- Wind proof and water proof/resistant layer to keep the weather out

There is however a important difference with the outdoors. For emergency kits, you need clothing that can be stored compacted for long periods of time and preferable durable enough to be used in less than optimal conditions.

There isn't much difference between outdoor under layers and emergency clothing. Insulation layer is a different story. With a move to ever lighter and smaller equipment, synthetic fiber or down filled jackets have been appearing as a insulating layer, replacing the traditional wool or fleece. In a preparedness point of view this lighter and smaller alternative to wool and fleece is not a solution. Emergency equipment is generally stored in kits or containers for years. This means equipment is compressed for longer periods of time. Synthetic or down require the fibers to loft to create insulation. Compressing them for long periods of time will reduce there lofting ability and making them less insulating (we are talking years on end here). Compressing fiber insulation for the first time, will cause the most reduction in loft. The compression after that are still harmful in the long term, but not as bad as the first time. If you are planning to replace them every few years, than you could use fiber based insulation. Not compressing them is also a option when space is not a issue. Wool and fleece do not compress well, but they do retain there insulating value in long term storage. They are also generally a lot more hard wearing than the insulating or down filled jackets (these generally have super thin and light outer shells).

I would also recommend fleece over wool. Fleece is much cheaper, lighter and dries out far quicker. Wool itches, stays wet for long periods of time and make you smell like a wet dog. Wool does however protects against spark, while fleece doesn't.

For the outer layer, the ultralight exteriors (Pac-lites, etc) are to vulnerable. Choose a stronger version, preferable with reinforcements on hard wearing locations. Thicker, more durable outer layers generally don't breath as well, so choose one with ventilation zips to get moisture out.

The problem with the insulating jackets not only apply to clothing, but also to sleeping bags and blankets. Synthetic and down sleeping bags are also not suitable for long term compressed storage. So use fleece or wool blankets, unless you want to replace the bag every few years. One other note, if sleeping bags are store in a reasonable accessible location (compressed or not), they will probably be abused and used a moving blankets. Things need to be moved in warehouses and moving blankets can be hard to find...

Marking your equipment

Marking your gear has many (useful) purposes:
- Identify what is yours
- Find the gear (brightly colored equipment helps)
- Put indicators or 'red flags' on your gear 


First of all make sure whatever you use does not affect your equipment in a negative way. Pay particular attention to personal protective equipment. The glue in stickers/tape and solvents in markers/paint can have effect on certain materials (especially plastics and textiles). Sometimes manufactures will sell specific stickers or markers to mark their products (helmets , rope, slings). Preferably mark your equipment on a part which is not safety related. If you have doubts, you can choose to tie strings or add zip ties with a tag to your equipment, which means there is no solvents of other chemicals interacting. (unless the string was contaminated)  

Second, make sure the markings does not get in the way. It can block the sight to parts of your equipment, both in operating the equipment, as well for inspections of your equipment (wear and tear, damages, etc). If string is used, make sure it won’t cause entanglement or choking hazards.

Third, make sure the markings can handle the environment it is being subjected to. This can be extreme temperatures, temperature swings, exposure to abrasion or even chemical exposure. For example; adding (reflective) tape to firefighting equipment can simply mean that the tape melts the first time you get close to a fire. Meaning you have to clean of the melted goo.

You can make your markings have additional function. Strategic markings can act like warning flags. For instance a visible red line when something is forgotten or a switch is set on life. Markings can also be zipper tabs, making it easier to locate and open a certain compartment. Or just a loop, so you can hang your equipment in storage. 

For finding and identifying equipment I use the following to make my gear stand out:
- Bright neon yellow reflective tape (a thick high quality version, which is also very abrasive resistant).
- Bright red cordage with reflective threads in it.
- Glow in the dark and reflective cordage. (white)
- Glow in the dark and reflective zipper pull tabs.

For safety markings or surfaces which does not allow tape of anything attach to it, without creating problems:
- Permanent markers (works best on rough surfaces, specialist markers are available for certain equipment)
- Nail polish (works best on smooth surfaces)

Note that sometimes you just can’t mark your equipment without causing a problem and sometimes you can only mark things on the inside.

Keysafes

Need to leave keys out for somebody else or can't carry the key with you? Everybody know the usual hiding place;  under the doormat, behind a plant, in the bumper, on a car tire, etc. Obviously not the most safe methods.

So what do we do when we need to leave a key at a door or car without having the keys stolen? One method of safely leaving a key for somebody else is a keysafe with a number lock.

Keysafes are available in different sizes and shapes. There are versions which are design to bolt on to a structure and those that look like a giant padlock, allowing you the secure the keysafe to a object. There is a obvious risk that people see such keysafes and attack them for the keys. So hide them can't hurt.

Padlock style keysafe.

Training rescue personel; the old fashion way

Some things are sometimes best kept simple. One of these things is training people what to do. Sometimes it's explaing structures, how they are made and how to deal with them. Sometimes you want to explain how to follow procedure and why. One simpel methode is the use of models. 

Here is a nice example of a model to explain thatched roof construction and how to fight fires with thatched roofs. Patches of canvas is used to simulate the strips of thatching and is removable from the model to reveal the interieur structure. 


Or just scale models of environments with various kind infrastructure. This is very usefull on teaching how to approach a scene and how to locate everything. Nice things about this particulair setup is the fact that these are actually puzzels. Multiple models can be joint to make a bigger envionment. 


But when do you get a birds eye view of a situation in real life? One way to get the right point of view is have people crawling inside a classroom, but thats not very user friendly for the student. Another simple, yet effective solution is to just put in on top of a extra high table.
