Which of the following is NOT a function of a roof hook in ventilation operations?

• A. Provide handholds
• B. Assist in moving or removing roofing material
• C. Create safer working surfaces
• D. Cut through roofing material

Answer: (D)

In ventilation operations, the roof hook is used to provide handholds for grip and stability, assist in moving or prying up roofing material to access the opening, and help establish a safer working surface by giving a secure point to lean on or step from. It enables crew members to maneuver along the roof and expose the vent without relying on unstable footing. Cutting through roofing material, however, is not a function of a roof hook; cutting requires a separate tool such as a saw.
