Below is a method I used in another life to assess risks for my employer. Maybe you will find it interesting and even get a few ideas. I guess there was a formatting issue because the chart listing all the identified hazards didn’t come over. Regardless, if anyone likes you can list those risks in your area, or even possible risks like nuclear war, and score it.
HAZARDS ANALYSIS SUMMARY TABLE/SCORE
INSTRUCTIONS
Each of the four criteria identified for describing and assessing potential hazards is to be assigned a descriptive term and number as follows:
Low 1-2
Medium 3-4
High 5
The criteria for each hazard is assigned one of the five ratings above and then totaled to determine a “score.” All listed situations refer to major disasters causing loss of life, human suffering, and property damage. Day-to-day emergencies or accidents that are routinely responded to by local emergency organizations are not included.
1. The HISTORY rating is derived by the number of occurrences of the type of disaster under study over the past 25 years. If it has not occurred and if conditions have not changed to increase the hazard, the rating is “low;” once in 25 years – “medium;” and two or more times – “high.”
2. Estimates of VULNERABILITY can be derived by comparing the area at risk to the population and property density. For example, thinly populated rural jurisdictions near nuclear power plants are considered less “vulnerable” than more heavily populated urbanized ones.
3. The MAXIMUM THREAT is the greatest destruction that could occur for the disaster under study. For example, with a nuclear attack, jurisdictions with a high-risk or target area receive a “high” rating; those within 30-40 miles, “medium;” and other, more remote jurisdictions, “low.”
4. The PROBABILITY of a disaster is a subjective judgment to be made primarily by local officials. The following guide may be used:
a. Chances per year greater than 1 in 10 “High”
b. Chances per year between 1 in 10 and 1 in 1,000 “Medium”
c. Chances per year less than 1 in 1,000 “Low”
