Overview

As an index to measure safety,

• To what level should safety be increased
• How to improve safety

The two are basic.

Regarding the level of safety to be increased, it is practical to completely eliminate the dangerous condition, that is, to increase the safety endlessly becomes very expensive, or interferes with daily life and economic activities. Not. Therefore, the goal is whether or not the risk can be eliminated (hazard does not occur) at a level that maintains its usefulness economically. High safety in the general public does not mean that there is no harm.

How to improve safety has been empirically implemented in each field since ancient times. When a new technology is discovered or developed, it has risks and harms due to lack of experience to use it safely, but it will become clear how to avoid the danger by accumulating experience, so implement them accordingly. Have been improved.
