How are macro times defined in fire investigations?

Macro times in fire investigations refer to extended periods that encompass significant spans before the occurrence of a fire, often lasting months or even years. This concept is critical in understanding the timeline of events leading up to a fire, which can include factors like the history of the property, previous fire incidents, or changes in occupancy and usage. Analyzing these macro times helps investigators ascertain patterns or behaviors that may have contributed to the fire event.

In the context of fire investigations, distinguishing between macro times and other timeframes ensures that investigators can differentiate between long-term factors and immediate circumstances surrounding the fire. This understanding is essential for establishing a comprehensive narrative and identifying potential causes.
