I. INTRODUCTION TO ENTRY (7-1)
When and Where to Enter
• Rescue requires immediate ventilation to remove smoke and heat and decrease danger to victims
• Firefighting ventilation can be delayed until hoselines are ready
Basic Door Construction
• Doors are made of metal or wood
• Doors may be single doors or double doors
• Doors may be solid or lighted (with glass)
• Doors may be exterior (heavier and solid) or interior (lighter and hollow core)
• Doors operate on hinges set in a frame of metal or wood
• The stop on the door frame that is part of the frame is the jamb (usually metal frames)
• The stop on the door frame that is attached to the frame is the stop (usually wood frames)
• Doors either open in (hinges on inside) or open out (hinges on outside)
Locking Devices in General Usage
• Mortise lock - positioned in edge of door with keyway and opening device separate
• Bore-in - keyway in door knob
• Rim - lock mounted on back of door with cylinder through door
• Adams-Rite - used on commercial doors with metal frames and glass
II. ENTRY THROUGH DOORS AND WINDOWS (7-2)
Entry Through Doors
• Commercial occupancies: front
• Almost easier to force entry through front door than rear
• In older buildings, front door might be constructed of wood or wood frame with ordinary glass
• In modern structures, front door made of tempered glass or heavy plate glass in strong frame
• Rear doors usually made of steel or reinforced with steel
• Front door protected by metal shutters, accordion-type barred grating, or similar devices
• Wooden doors
• May or may not have cylinder locks
• Usually has bolts that engage keepers at top or bottom of door or both
• Double doors can be bolted to each other; pulling or forcing lock does not guarantee entry
• May have center panels which can be broken out for entry or opening door
• Commercial occupancies: rear
• Steel doors
