you may use the same thing, but do you use the same container ? test the water container in your PSK.
can't think much more than that. making a shelter is good, making a water container which is suitable to boil water is good, making fire to warm your self, dry your clothing, boil you water and if needed cook food, but thats the last on the priority list of survival. Where are you going to try to light a fire ? i thought "staat bosbeheer" fine people for that. GOt any secret place to light a fire in the wild legally, on public land ?
