CFI Fire Investigation Reporting & Documentation 2 — Questions and Answers
Question 1: When documenting a fire scene, what is the correct sequence for photographic documentation?
- Close-up, medium, overview
- Overview, medium, close-up (Correct answer)
- Medium, overview, close-up
- Close-up, overview, medium
Correct answer: Overview, medium, close-up
The standard photographic sequence progresses from general overview shots to medium range and finally close-up detail shots to establish context before capturing specific evidence.
Question 2: Which element is REQUIRED in every fire investigation report according to NFPA 921?
- Insurance policy numbers
- Names of all neighbors interviewed
- The investigator's methodology and reasoning (Correct answer)
- Estimated reconstruction cost
Correct answer: The investigator's methodology and reasoning
NFPA 921 requires that investigators document their methodology and scientific reasoning process so conclusions can be evaluated and replicated by others.
Question 3: A fire investigator is documenting burn patterns on a wall. Which documentation method provides the most accurate spatial relationship between patterns?
- Narrative description only
- Sketched diagram with measurements (Correct answer)
- Photographs alone
- Witness statements describing the patterns
Correct answer: Sketched diagram with measurements
Scaled diagrams with measurements provide accurate spatial relationships between burn patterns that photographs alone cannot convey due to perspective distortion.
Question 4: When writing the 'cause of fire' section of a report, an investigator should base the conclusion on:
- The most common cause for that occupancy type
- Physical evidence and data collected during the investigation (Correct answer)
- Insurance company findings
- Witness statements alone
Correct answer: Physical evidence and data collected during the investigation
The cause determination must be supported by physical evidence and data collected through systematic investigation, not assumptions or statistics.
Question 5: What does the term 'chain of custody' mean in the context of fire investigation documentation?
- The order in which witnesses are interviewed
- The hierarchy of command during the investigation
- The chronological record of evidence handling from collection to court (Correct answer)
- The sequence in which fire spread through a structure
Correct answer: The chronological record of evidence handling from collection to court
Chain of custody documents every person who handled evidence from collection through analysis and trial, ensuring evidence integrity and admissibility.
Question 6: An investigator discovers that a key piece of physical evidence was accidentally destroyed before being photographed. What is the appropriate course of action?
- Omit any reference to the evidence in the report
- Document the loss in the report and note its impact on the investigation (Correct answer)
- Recreate similar evidence for documentation
- File the report without mentioning the destruction
Correct answer: Document the loss in the report and note its impact on the investigation
Investigators must document the loss of evidence, how it occurred, and how the loss impacts the investigation's conclusions to maintain report integrity.
Question 7: Which type of diagram is MOST useful for documenting the spread of fire through multiple rooms of a structure?
- Elevation drawing
- Floor plan with fire spread indicators (Correct answer)
- Site plan showing exterior only
- Isometric perspective drawing
Correct answer: Floor plan with fire spread indicators
A floor plan with fire spread indicators shows the horizontal progression of fire between rooms and areas, making it the most effective diagram for documenting fire spread patterns.
