When does a 1st aid kit (tick-tool, plasters, pain-killers, Zinc Oxide Tape etc etc) become an emergency bag item ?
When does 'daily usage stuff' (toilet roll, trowel, hand wash, head-torch) become an emergency bag item ?
When does food and drink (water filter, flap-jacks, dextrose tablets, 'ration-packs') become an emergency item ?
Why would you carry a space-blanket and an emergency shelter when you are already carrying a Tent, mattress, and a sleeping bag ?
I would view the following as 'emergency kit' (everything else can be sorted by the 'normal' planned kit) Emergency Kit is just that - to help get out of / resolve an unplanned 'situation'.
Boot laces
Pen Knife
Whistle
Spare Batteries
Lightweight (175g) Wood stove for when / if I run out of gas.
Spare guy-rope, Spare tent pegs, Spare tent pole repair splice.
Spare Spectacles.
Sewing Kit
Mirror / Heliograph
Few metres of Paracord
If the question is about an EDC (every day carry) pocket emergency 'tin' mine has :
2x Condoms
1x T-Light
1x Lighter
Bits of paper (to start fire)
3x Plasters
6x Cotton buds (to help start fire or clean wounds)
2x Cotton Wool-Pads (to help start fire or clean wounds, or act as a bleed-pad)
1x Stanley Knife blade

All fits into a tobacco-tin.
