- Weather phenomena such as hurricanes, tornadoes, and floods
- Biological hazards such as diseases, invasive species, and pandemics
Anthropogenic Hazards
- Industrial accidents and technological failures
- Environmental pollution and radiological contamination
- Cybersecurity threats risks to information systems
Characteristics
Hazards are typically characterized by:
- Probability of occurrence
- Potential severity of impact
- Spatial extent of effects
- Duration of impact
- Speed of onset

- Administrative measures
- Personal protective equipment
- Early warning systems and monitoring
Response and Recovery
Regulatory Framework
Various organizations and standards govern hazard management:
- Occupational Safety regulations
- Environmental protection guidelines
- International standards requirements
- Industry-specific protocols
Emerging Concerns
Modern developments have introduced new categories of hazards:
- Climate change related risks
- Technological dependence vulnerabilities
- Global supply chain disruptions
