Survival Card Packets

If you were to design a series of survival card packs of tips and hints, what categories would you include?

The idea is for packets of cards similar to the Brunton Pocket Survival kit.

3 or 4 thin plastic printed cards to a packet.

The cards fit into a plastic envelope that would in turn fit a credit card slot in a wallet.

I am not really looking for what exactly would go on each card but the general categories of each packet. Details will come later.

An Example would be a First Aid pack. The cards would list general first aid tips. Such as How to do CPR or pressure points chart to control bleeding ETC, ETC.

The idea of the cards would be to jump-start the brain in an emergency situation. Another use would be you are stranded with a group. You have the knowledge but can only be in one place at a time. The group is broken into small parties to perform different tasks for the group’s survival. Each task party could be given the packet that it covers.

While all the skills for the task could not be covered this beginner or basic information can get the jobs started.

So what areas should be considered?
