Could you please explain the differences between several words?

In the field of safety, what are the differences between the terms hazard, risk, and failure? ? The most important ones are the first two words: handshake
In risk management, the term “hazard” is used to refer to an event that may cause harm, whereas the term “risk” is used solely to indicate the probability of that event occurring. In risk management, the term “hazard” is used to refer to an event that could cause harm, while the term “risk” refers simply to the probability of something happening.
In systems safety engineering, it is understood as follows: hazard: a danger, an unacceptable condition that may cause harm to people, objects, or systems. risk: Risk is the combination of the likelihood of harm occurring and the consequences thereof. Failure: A malfunction, an defect present in a system, device, or program.
What was said upstairs is correct. From the perspective of hazard analysis, let me explain: Risk is the combination of consequences and the likelihood of their occurrence. A comment on the entire system: Hazard refers to the consequences, such as fire, explosions, etc. Failure refers to the malfunction of equipment or control systems, and it is often the cause of hazards. In other words, due to the failure of equipment or systems, various hazards arise. By analyzing the likelihood of such failures, it is possible to determine whether the associated risk is acceptable.

The fourth floor of the post explains the relationship between the three elements quite clearly; I would like to add one more thing: due to equipment or system failures, various hazards arise. By analyzing the likelihood of such failures as well as the severity of the consequences of those hazards, it is possible to determine the level of risk. Simply put, the method for determining risk is risk = severity of consequences * likelihood. As for whether the risk is acceptable, a specific analysis is needed based on different economic conditions, safety measures, and preferences.
When discussing hazard and risk, an example was given: there is a shark in a pool, and a person is walking outside; the shark poses no threat to that person. The danger posed by the shark is the hazard, while if the person enters the pool, then the risk arises. In fact, hazard refers to the inherent danger of a thing itself, while risk refers to the potential harm that hazard may cause to the environment or people. I have a video on hazard and risk; those who need it can upload it via QQ.
