ENTRY AND VENTILATION

SPO The student will demonstrate a basic understanding of forcible entry tools and techniques by applying the material in a practical setting.

EO 7-1 Explain the basic principle associated with forcible entry including the need for such entry

EO 7-2 Explain the entry techniques for selected doors and windows.

EO 7-3 Explain the principles and benefits of ventilation.

EO 7-4 Explain the natural, mechanical, and hydraulic ventilation procedures.

This lesson should be delivered as a combination of demonstration and student practice with the minimum amount of time spent on lecture. This material is designed to give the student some basic information on entry and ventilation. It is not intended to replace a Firefighter I program nor make the individuals fully-functional firefighters. It includes some basic information that any new firefighter should know to assist in an exterior mode on the fireground. Instructor should have tools, ventilation equipment, and props or a structure available for display, demonstration, and handling.

I. INTRODUCTION TO ENTRY (7-1)

A. When and Where to Enter

  1. Rescue requires immediate ventilation to remove smoke and heat and decrease danger to victims

  2. Firefighting ventilation can be delayed until hoselines are ready

B. Basic Door Construction

  1. Doors are made of metal or wood

  2. Doors may be single doors or double doors

  3. Doors may be solid or lighted (with glass)

  4. Doors may be exterior (heavier and solid) or interior (lighter and hollow core)

  5. Doors operate on hinges set in a frame of metal or wood

  6. The stop on the door frame that is part of the frame is the jamb (usually metal frames)

  7. The stop on the door frame that is attached to the frame is the stop (usually wood frames)

  8. Doors either open in (hinges on inside) or open out (hinges on outside)

C. Locking Devices in General Usage

  1. Mortise lock - positioned in edge of door with keyway and opening device separate

  2. Bore-in - keyway in door knob

  3. Rim - lock mounted on back of door with cylinder through door

  4. Adams-Rite - used on commercial doors with metal frames and glass

II. ENTRY THROUGH DOORS AND WINDOWS (7-2)

A. Entry Through Doors

  1. Commercial occupancies: front

      a. Almost easier to force entry through front door than rear

          1) In older buildings, front door might be constructed of wood or wood frame with ordinary

              glass

          2) In modern structures, front door made of tempered glass or heavy plate glass in strong frame

          3) Rear doors usually made of steel or reinforced with steel

          4) Front door protected by metal shutters, accordion-type barred grating, or similar devices

      b. Wooden doors

          1) May or may not have cylinder locks

          2) Usually has bolts that engage keepers at top or bottom of door or both

          3) Double doors can be bolted to each other; pulling or forcing lock does not guarantee entry

          4) May have center panels which can be broken out for entry or opening door

  2. Commercial occupancies: rear

      a. Steel doors

          1) Before attempting to force, checked for exposed locks or hinges
