Who is responsible for assessing the potential risk of a hazard and if the level of risk is acceptable determining if something needs to be done to lower the risk?

The responsibility for assessing the potential risk of a hazard typically falls to risk managers or safety professionals within an organization. They evaluate the likelihood and severity of hazards and determine if the associated risks are acceptable. If the risk is deemed unacceptable, these professionals recommend and implement measures to mitigate or eliminate the risk. Additionally, regulatory agencies may also play a role in setting standards and guidelines for risk assessment.
