What is the final action when completing a 45° inspection cut?

• A. Roll 1 rafter
• B. Cut perpendicular to exterior wall
• C. Continue 6-10 inches
• D. Remove triangle

Answer: (D)

Completing a 45° inspection cut means removing the triangle that forms at the end of the cut. That triangular piece is the waste from shaping the opening; taking it out finishes the cut and creates a clean inspection opening for viewing the space above and for ventilation. This lets firefighters see into concealed areas to assess fire extension and plan further action.

Rolling a rafter would be a separate maneuver not tied to finishing an inspection cut, cutting perpendicular to the exterior wall isn’t the final step of this cut, and continuing 6-10 inches would leave the cut unfinished. Removing the triangle precisely completes the opening needed for inspection and ventilation.
