Which action is part of Roof Flap Back Procedure?

• A. Cut windshield; Cut A, B, C posts; Relief cut roof and crease
• B. Lift roof off
• C. Flap forward
• D. Flap Down

Answer: (A)

Roof Flap Back relies on creating a controlled hinge so the roof can be folded back for interior access. The proper sequence starts by cutting the windshield to give the roof a hinge point and prevent the glass from binding. Then cutting the A-, B-, and C-posts frees the roof edges from the pillars, allowing the roof to detach from the body shell along those edges. A relief cut along the roof crease relieves tension and guides the roof to bend neatly, forming a stable hinge line. With these cuts, the roof can be flipped back as a single hinged panel, providing safer, easier access to the patient. Lifting the roof off would remove the entire roof rather than hinge it back. Flap forward or flap down describes moving the flap in directions that don’t establish the proper hinge and edge separation for this technique.
