In what situation would the 10-13 code be applicable?

The 10-13 code is specifically used by the NYPD to indicate that there is a fire alarm at a sensitive location. This code provides crucial information to dispatchers and responding units, allowing them to prioritize their responses based on the potential for danger, especially in areas where a fire could pose a higher risk, such as a hospital or school.

In contrast, the other scenarios do not align with the specific nature of the 10-13 code. For instance, unauthorized entry is more related to burglary or trespass calls, while evacuating a building entails specific protocols that go beyond merely reporting a fire alarm. A routine police check does not typically involve the urgency or specificity of the situation denoted by the 10-13 code. Thus, the context of the scenario is critical in identifying the appropriate use of police codes for effective communication.
