What aspect of risk assessment assesses the degree of harm that may arise?

The correct choice focuses on "severity," which pertains to the extent of harm or adverse consequences that may result from a particular hazard or risk. In risk assessment, evaluating severity involves understanding how serious the impact can be on individuals, property, the environment, or operations if a risk were to materialize. This could relate to injuries that could be sustained, the potential for long-term health effects, financial repercussions, or damage to equipment.

In risk management frameworks, severity is typically a critical factor because it helps prioritize risks based on potential impacts. Knowing the severity allows for better decision-making in implementing control measures and ensuring that resources are allocated effectively to mitigate the highest risks.

The other choices serve different aspects of risk assessment. Probability assesses how likely it is that a risk will occur; degree of damage might seem similar but generally refers to the quantifiable extent of impact, which can include severity; and frequency addresses how often a risk might happen, which is distinct from the severity of its consequences. Hence, understanding severity is essential for comprehensively addressing potential risks and potential harm.
