F-89 Emergency Action Plan (EAPD) / Fire Safety Director (FSD) Practice Exam

What are the three conditions that determine the impact of a bomb detonation on people and property?

1. Size/type of device, distance to structure, time of day

2. Size/type of device, distance to structure, building design

3. Size/type of device, building location, number of people

4. Size/type of device, building age, existing hazards

The correct answer is: Size/type of device, distance to structure, building design

The correct answer, which highlights the three conditions that determine the impact of a bomb detonation on people and property, includes the size/type of device, distance to structure, and building design. The size/type of device is critical because different explosive materials and configurations produce varying levels of blast effects. Larger devices or those that are designed to maximize damage can lead to more substantial impacts on surrounding structures and individuals. The distance to structure is vital since the further away a building or group of people is from the point of detonation, the lower the likelihood of severe effects. Blast waves dissipate over distance, meaning structures closer to the explosion are at a higher risk of damage and occupants are more susceptible to injury. Building design plays a significant role in how well a structure can withstand or mitigate the effects of an explosion. Stronger designs using appropriate materials can absorb some of the blast energy, potentially saving lives and reducing property damage. Conversely, poorly constructed buildings may collapse or suffer extensive damage during an explosion. In contrast, the other options introduce variables that might not provide as direct a correlation to the impacts of a bomb detonation. For instance, the building location, while generally important, encompasses too broad a range of considerations to be as definitive as the specified factors
