What is the difference between a hazardous production factor and a harmful production factor?

Danger and harm are different things, but interrelated. In the presence of danger, there may not always be harm. There are certain risks in production. They can have several levels: unlikely, with medium probability and with a high level of threat. Risks are impossible to predict in some cases. It is also impossible to predict when the risk will turn into harm to workers, the environment and others. But the harm is known in advance and all employees consciously receive harm. There are also different levels of harm.
