Final answer:
The prerequisite step before Layan, the safety coordinator, engages in risk assessment is the identification of hazards. Once hazards are identified, the appropriate risk assessment method can be chosen, and participant consent can be secured.
Step-by-step explanation:
Before engaging in a risk assessment, Layan, as the safety coordinator at the workplace, should carry out the prerequisite step of the identification of hazards. This step is crucial as it lays the foundation for the entire risk assessment process. Only after pinpointing potential hazards can a coordinator determine which risk assessment approach to use, be it qualitative, quantitative, or a combination of both. Moreover, it is essential to ensure that employees and participants are fully informed and consent to any safety procedures or assessments that will take place. This ensures that everyone is aware of and agrees to the processes and practices established to maintain safety in the workplace.
