During fire suppression, finding holes in floors or difficulties attacking the fire may trigger suspicion of what?

When encountering holes in floors or experiencing difficulties while attacking a fire, the presence of such anomalies can raise suspicions of arson. Arson is characterized by intentional acts to cause or enhance a fire, which can manifest in various ways, including the creation of vulnerabilities in structures—such as holes in floors—that may hinder firefighting efforts.

These indicators can suggest that someone deliberately tampered with the environment to facilitate the fire's spread or to disrupt firefighting operations. Firefighters are trained to look for signs that might indicate foul play, and unusual structural damages often inform their investigation. In contrast, while accidents, natural causes, and faulty equipment can indeed lead to unexpected challenges in fire suppression, they typically don't manifest through the same physical signs that suggest intentional damage. Thus, the presence of those specific red flags strongly correlates with suspicions of arson.
