What needs to be clarified
Determine which time boundaries independent records support, distinguishing system registration of a signal from the inferred start of burning and the operator's subsequent actions in the available materials.
Materials to prepare
- Original panel event export with code definitions and time settings
- Original video files with metadata and camera-clock information
- Dispatch log and system inspection record describing its condition
What to compare
Message types, recording sequence, time zones and supported clock offsets are compared. File continuity and shared events that can align timelines are checked. Visible smoke, detector activation and operator action are treated separately; uncertainty intervals remain explicit when source records do not establish one exact timestamp.
Possible outcome of the analysis
A reconciled timeline may show time intervals, references to original records and unresolved discrepancies, helping formulate further questions about the event's development and the adequacy of available evidence.
Limits of the conclusions
An alarm timestamp does not automatically establish fire onset or cause. Unsynchronized clocks may prevent an exact sequence; record analysis does not certify the system's past operability.
