What is the term used for a building that is unsafe in case of fire due to its flammability or inadequate exits?

The term "fire trap" is used to describe a building that poses significant risks in the case of a fire due to its flammability or inadequate exits. This designation indicates that the structure is likely to contribute to the danger of a fire situation, often because it lacks proper means of egress or has materials that readily ignite and propagate flames. A fire trap can lead to severe consequences, such as entrapment of occupants and increased difficulty for firefighting efforts.

In contrast, a "fire hazard" refers more broadly to conditions or materials that could potentially cause a fire, rather than describing a complete structure. A "fire escape" is specifically a designated exit used to escape a building during a fire emergency, while "fireproof structure" suggests a building designed with materials resistant to flames, which is not applicable in the context of a building deemed unsafe due to these reasons. Thus, identifying this type of building as a fire trap accurately reflects its critical safety issues.
