1. Risk identification: This stage involves identifying potential hazards that could cause harm or damage to people, property, or the environment. The hazards can be physical, chemical, biological, or psychological in nature .
2. Risk analysis: In this stage, the identified risks are analyzed to determine the likelihood and severity of their occurrence. The analysis helps in prioritizing the risks based on their potential impact and likelihood of occurrence .
3. Risk evaluation: This stage involves evaluating the risks based on their analysis results and deciding on appropriate measures to manage them. The evaluation helps in determining whether the risks are acceptable or not and whether further action is required to reduce or eliminate them .
