Where I live, the main threats for me and my family are natural disasters (high threat), dangerous overseas drivers (high threat) and unpredictable overseas travellers (low to medium threat). There are and always will be threats and dangers outside of those but they are the main three which pose the most danger to myself and my family and which I base my threat assessment and survival plan off.
Making a personal threat assessment requires a bit of thought and research of threats that occur in your geographical area. In urban environments threats may come from hostile people, in some areas wildfires or flooding may be the threat. We live in a high-risk earthquake area and have many overseas travellers who do not have the skills required to handle the roads safely.
A survival plan is basically a detailed mental and written plan of how you respond to those threats short and long term, how you use/mobilise your assets and limit your liabilities. Again your survival plan is dependent on threats prominent in your area. Firstly my survival plan is a mental reflex based of emotional bookmarking and experience in those areas, its no point having the most detailed written plan if you don't have the skills to react to the threat instantly. If an earthquake hits I need to know how to respond immediately to get my family to safety then I can go back to my survival plan and take stock of my assets and liabilities.
I have 3 levels regarding my survival plan.
1: Everyday carry. Items which I have on my person at all times. Phone, money, folding knife, watch, torch, para cord, tactical pen, tough footwear (even in the middle of summer, try running over debris or from a car crash in bare feet, sandals)
2: Survival bag in the truck. Assets I can usually reach quickly if needed. Jerry can with water, a few blankets, small axe, warm jacket, first aid kit, some food, large knife, rope and tactical gloves, day pack, torch and head torch, fire starting kit. All of these items are in a small box in the back of the truck, take up very little room and I hardly notice them.
3: Survival items at home (left in the sturdiest part of the house). Water and non-perishable food supplies, axe, machete, knife, first aid kit, blankets, fire starting kit, warm waterproof clothes, tarps, torch and headlamp, rope, large pack. I also have a solid understanding of emergency first aid, have the means to catch wild game and a deep knowledge of wild foods.
The idea behind making these assessments and plans is not to be paranoid, the idea is to be prepared based on realistic threats in your area. A consistent thought I have is that the detrimental effects of not being prepared and needing it, possibly having life-long consequences far outway the minimum effort required to make a basic threat assessment and survival plan. After the very small time investment required to make these plans, the benefits can be life-saving. I don't want to just survive, I want to thrive.
