Hazard classification plays a crucial role in risk assessment and understanding the effects on people and communities. By categorizing hazards, we can better evaluate their potential impacts, aiding disaster preparedness and response. Natural hazards, for instance, can be assessed using specific criteria, such as property damage thresholds and casualties.

Understanding these risks is essential for implementing effective control measures and enhancing public safety.
