The hazard-based approach is valid and very important, but it does not
interact well with the 'AoG' concept, since that denies that a current
hazard (such as a very near future volcanic eruption) is/has been
identified.

Hi John A. and all:
A different process than “risk assessment:”
A hungry polar bear is a hazardous energy source. The bear’s energy
exceeds John A.’s defensive energy, thus John A. can expect to be
injured or worse during a polar bear encounter.
The safeguard for John A. is distance.
However, if the London Zoo had a polar bear (it doesn’t), the
safeguard would be a fence or cage or some other form of polar bear
containment. Assuming the containment method is reliable, the
probability of John A. injury from a London Zoo polar bear is no more
than the distance safeguard.
When John A. climbs a ladder, he has potential energy that increases
with increasing height on the ladder. If he should fall, the
potential energy is converted to kinetic energy imparted to the body
when it collides with the ground.
The principal safeguard is behavior (skill).
A supplemental safeguard could be a harness which would arrest his
fall before he hit the ground.
I have considered “energy” imparted to the body as the cause of
injury. And, I have identified one or more safeguards for prevention
of transfer of the energy to the body. As I said, a different approach.
Best wishes for the holiday season,
Rich
