Which of the following defines a man-made disaster?

• A. An event caused by people that brings great damage, loss, or destruction to the facility, such as chemical spills, a water main breaking, a plane crash, a train derailment, or a fire; may be unintentional and accidental
• B. A natural event like hurricane
• C. An event that disrupts normal operations
• D. A planned maintenance outage

Answer: (B)

Understanding the difference between man-made and natural disasters is key. A man-made disaster is an event caused by human actions or failures that leads to significant damage, hazards, or disruption—such as chemical spills, infrastructure failures, transportation crashes, or fires that originate from human activity or error and can be accidental. This focus on human involvement and potential for widespread harm makes it the best description, because it highlights why responders must address hazardous conditions, protect people, and coordinate rapid incident management. The other options describe a natural disaster, a vague disruption of operations, or a planned outage, none of which center on human-caused harm or require the same urgent, hazard-focused response.
