Forcible Entry (7th Edition)
Chapter 9-Through-the-Wall Entry
Test Review

• Buildings are structurally supported by walls or a structural frame.
• Partition walls are interior non-load bearing walls.
• Curtain/Panel walls are exterior non-load bearing walls.
• Fire resistance ratings for exterior masonry walls range from 2 to 4.
• When a building is subdivided with numerous fire-resistive walls it is said to be compartmentalized.
• Walls with voids provide a path for fire spread.
• Interior combustible walls add fuel to fire.
• Curtain walls provide little resistance to fire spread.
• Platform-frame construction is more fire resistive than balloon-frame construction because their wall plates act as fire stops.
• Well-insulated buildings will trap heat inside a structure, therefore increasing rate of fire acceleration.
• The primary safety concern with through-the-wall entry is whether structural integrity will be compromised.
• Load bearing walls may be either interior or exterior.
• Precast concrete walls are fire resistive, may be load- or non-load bearing, and have single panels that can weigh 20 tons or more.
• Brick walls should be considered load bearing until proven otherwise.
• Brick veneer walls are difficult to distinguish from load bearing brick walls.
• Many kinds of insulation is flammable and will not stop fire spread.
• Gypsum board provides good fire resistance and is easily penetrable by forcible entry tools.
• Fire walls have a rated fire resistance of 4 hours.
• Fire walls must extend above roof level.
• Fire walls are designed to be self-supporting.
• Fire walls should have all openings protected by automatic-closing fire doors.
• Always assume that electrical and/or plumbing lines may lie behind brick veneer exteriors.
• When opening partition walls, always check for heat around the point chosen for opening.
• The height of a building determines whether a it is supported by walls or by the structural frame.
• When interior walls are non-load bearing, the structure is supported by columns throughout the interior.
• Building codes may require that fire-resistive partitions be located in corridor walls, stairway enclosures, and occupancy separations.
• The type of wall construction determines the method of through-the-wall entry.
• A masonry wall is best opened by a battering ram.
• Only 1 stud must be cut on a load-bearing wall before shoring is necessary.
