Which code should be dispatched for a lock in / lock out incident?

• A. Mailbox Fire
• B. Missing Person
• C. Lock In / Lock Out
• D. Hazmat - Mercury Spill

Answer: (C)

This question tests recognizing the dispatch code that matches a request for entry or exit assistance due to a lock. The code that fits this scenario is the Lock In / Lock Out code because it explicitly covers helping someone who is locked inside or outside a space and needs entry or egress support. It’s a public-safety service call focused on gaining access, not a fire, medical, or hazmat incident.

Why the others don’t fit: a mailbox fire would trigger fire suppression resources, a missing person call is about welfare checks or search/rescue, and a hazmat mercury spill requires hazardous materials responders. The lock-in/out code is the one that directly aligns with the requested service.
