In risk treatment measures, we find cases where we can devise measures to simultaneously deal with the level of impact and the probability of risk and hazard arising.
These two things must be clearly divided.
Risks and risks that have both a high level of impact and a high probability of occurrence are the most important risks, and it is necessary to think about prevention measures before they occur and treatment measures after they occur.
A low probability risk is a risk that can be ignored.
Making the mistake of considering how much of this risk is at stake is judgment for each project.
