A caller reports a tiger got loose from its cage at the zoo and has attacked a patron. The caller was able to run into a bathroom to hide but can hear both the victim and the tiger still outside. Which PDI's would you give?

• A. PDI C and PDI D
• B. PDI A and PDI B
• C. PDI A, PDI C
• D. PDI B only

Answer: (B)

The main idea here is to protect the caller from an immediate, ongoing danger while still gathering critical information for responders. In an active animal threat like a loose tiger, the priority is scene safety: instruct the caller to stay hidden in the bathroom, remain quiet, avoid leaving the shelter, and not engage with the animal. This minimizes the chance of provoking the tiger and reduces exposure to harm while help is en route.

At the same time, you need essential information to guide the response. Keep the caller on the line if it’s safe, and systematically obtain details such as the exact location, how many people are involved or at risk, the victim’s condition, and any description of the tiger’s appearance or behavior. This information helps responders plan the approach, coordinate with zoo staff or law enforcement, and know what hazards may exist when they arrive.

Other instructions that focus on immediate medical care or steps to control injuries would come after the scene is secured, so they’re not the priority while there’s an active threat outside the bathroom door.
