Step 3: Boil All Water - Fire Starters
Water Will Be A Major Issue! Humans are Walking Bags of Water.
In a major disaster, you may be faced with drinking from questionable sources. Your Best Rule is Always Boil Water. You must make fire. I suggest you carry at least three different methods: lighter, matches and a magnesium striker. WHY? Lighters can be defective or run out of fuel. Matches can be difficult in wind and bad weather. You do not want to rub sticks together. Even Survival Experts hate that one.
Magnesium can be carried safely in a small block, but when you scrap the edge into small grit, it will ignite with a spark. The striker is a metal bar that when struck by the edge of a knife, for example, causes that high temperature spark. The wooden handles version is slightly different. The wood is oil soaked and the scraper is used to strap the wood to form tender which lights easily, even after a half hour under water.
Another tip to accelerate fire starting is to carry Cotton rubbed with petroleum jelly. I carry them in old film canisters or prescription bottles, both of which are water-resistant.
The other benefits of fire are heat, cooking, medical, protection from animals and a signal for rescue.
