CPI Investigation Procedures & Methods 2

Question 1

When documenting a scene during a fire origin investigation, which photographic sequence is considered best practice?

Accepted Answer

Wide-angle overview first, then mid-range, then close-up detail

Answer

The standard photographic sequence moves from general to specific — overview, mid-range, then close-up — to establish context before capturing detail.

Question 2

A CPI inspector arrives at a loss scene and finds that contractors have already begun demolition. What is the MOST important immediate action?

Accepted Answer

Order all work to stop and document current conditions

Answer

Stopping further alteration and documenting existing conditions preserves remaining evidence and establishes the scene's state at the time of inspection.

Question 3

Which method is used to determine the direction of heat travel in a structural fire investigation?

Accepted Answer

Analyzing char depth patterns and burn indicators on structural members

Answer

Char depth and burn indicators on structural members reveal the path and direction heat traveled through a space.

Question 4

During an electrical fire investigation, an inspector discovers arc mapping evidence. What does arc mapping primarily help establish?

Accepted Answer

The sequence of circuit failures and the area of fire origin

Answer

Arc mapping tracks the locations of arc faults to reconstruct the sequence of electrical failures and identify where the fire started or traveled.

Question 5

What is the primary purpose of establishing a 'fire scene perimeter' during an investigation?

Accepted Answer

To control access and protect physical evidence from contamination or loss

Answer

A controlled perimeter limits who enters the scene, preventing evidence contamination, loss, or alteration by unauthorized personnel.
