What does the term 'empirical data' refer to in the context of fire investigation?

Empirical data in the context of fire investigation refers to information that is obtained through direct observation, experimentation, or experience rather than through theory or speculation. This type of data is crucial for investigators as it provides tangible evidence that can be analyzed and interpreted to understand the circumstances surrounding a fire incident.

For instance, an investigator may collect empirical data by observing the physical effects of a fire on structures, measuring burn patterns, or testing materials found at the scene. This firsthand information helps establish facts about the fire's origin, cause, and behavior, leading to more accurate conclusions about the incident.

Data based on theoretical predictions lacks the grounding in real-world observation necessary for effective investigation, while data that is purely subjective or derived from media sources may not hold the rigor required for a thorough analysis. Empirical data thus serves as the foundation of scientific inquiry in fire investigations, allowing for informed and evidence-based conclusions.
