Some things can go on keychains and therefore you may want to consider making a little keychain kit as well.
Third Part: Backpack.
You can place the following in the backpack. Well actually I'll refer you to another page for this one. But please read on for more information first.
Now here is the thing about the backpack. It should be similar to that of a 72 hour kit. However, it doesn't need to be. You can make what is called a get home bag (GHB). This bag is usually for up to a day or two, enough to get you home.
I'll ask you to check out the link for Get Home Bags Kit to get the information you are looking for.
Just a note here, that you can till put some food and water rations in the trunk of your car, even though the GHB will have some. If your ordeal requires you to stay in your car, or you are more than two days from your home or other safe haven for supplies, you will have food and water in the car to carry you through a little longer.
Please have a look at the pointers I placed in the sidebar to the right for some pertinent information on car emergencies.
Before considering to leave your vehicle, think it through carefully particularly in the winter and in the desert areas. In the winter people have died due to the cold, not making it to their destination. And in the desert areas, it has happened that people have left their car to go to a distant highway or town, only to succumb to dehydration and heat stroke.
Sometimes you are better off remaining in your car which can act as a shelter until help arrives.
Remember the Elements of Survival (Priorities of Survival), in that they may apply to an urban scenario as well as a wilderness scenario, and everything in-between for that matter as well. This means that you may need to signal your presence to others to let them know you are in trouble and need assistance.
Emergency communications are important, therefore it can be good to have a ham radio, FRS/GMRS or even a CB if that is all you have with you in the car as well.
Have a fully charged cellphone with a power bank and/or a 12 V accessory adapter for the cigarette lighter socket to recharge from there. It won't drain your car battery that much for light use of your smartphone, however if for any reason your battery dies, it would be good to have a power bank. Use your car batteries power sparingly, especially if you had run out of gas and may need to signal using the headlights, or honk the horn etc.
Spare the gas that is left in your car if you went off the road by not leaving the car on continually, even in the winter. Use the dome light sparingly. It is preferable to use a headlamp or flashlight instead. Glow sticks can be used for this as well as for signaling. Make a light windmill by attaching the glow stick to the end of a rope about two or three feet long, and twirling it in the direction you want to attract attention from.
Leaving your car hood up, placing an orange cloth on the antenna, using your hazard lights or a sign in the window or side of the road, are all methods of attracting attention. Flashing your lights and honking the horn are others.
If you use a candle in the car, or you are stuck in the snow and use the engine to warm you up, crack the windows just a bit for fresh air and to ventilate any carbon monoxide that may build up in the cabin. Be certain that the muffler isn't blocked by snow, and if you know you have a muffler leak and/or a hole in the floor, carbon monoxide can enter all the more easily. Open the window a bit less on the upwind side, and a bit more on the downwind side. This is so that you do not lose all the warm air in your car. However, make a judgment call according to your circumstances.
Smartphones are notorious for being power hungry, unlike the 'dumb phones' of old.
you know that if you have an old phone lying around that isn't
connected to a specific carrier, that in some places it is required by
law to still have access to 911 emergency calls? Just leave the old SIM
card in there, but it isn't necessary to. Check your region to see if
this is available to you. Some people do not want a mobile phone but
they may consider having an unactivated one in their glove compartment.
