OBJECTIVE 2-11.6.1. Doors
49
Opening Doors TRY BEFORE PRY If door is locked – examine construction – determine method of operation – examine lock – Force? Find other methods of entry? – Use easiest, quickest, and least damaging method.
50
Forcible Entry Procedures Doors – TRY BEFORE YOU PRY Swinging toward Firefighter – insert blade of tool between door jamb and lock – force blade in against the rabbet or stop by working and pushing tool – pry tool away from the door to move the door and the jamb apart – pull door open or pry open with another tool when the lock has cleared its keeper
51
Forcible Entry Procedures Swinging away from Firefighter – break glass – stand to the windward side of the glass pane to be broken – strike tool at the top of the pane, keeping hands above the point of impact – remove ALL glass including jagged pieces from the sash with axe or other appropriate tool
52
Forcible Entry Procedures Break lock Stopped jamb – bump the cutting edge of tool against stop to break paint or varnish so blade can be inserted – loosen stop at the lock or remove stop completely – start blade between door and jamb – make initial pry only after the blade is halfway in, this is to permit the blade to be worked and pushed
53
Forcible Entry Procedures – With full bite behind door pry door away from jamb until bolt passes keeper
54
Forcible Entry Procedures Rabbeted Jamb – lay blade of tool flat against door, insert blade between rabbet and door – make short pries with first tool to spread jamb – work blade of second tool between door and jamb, hammering blade well into opening – with full bite behind door, pry door away from jamb until bolt passes keeper
55
Forcible Entry Procedures Inward w/ Rabbit Tool – Insert rabbit tool jaws next to lock between stop and door – Place one foot on leg of pump while holding jaws in place with hand – Grasp pump handle with free hand – Pump portable hydraulic pump while maintaining a grip on back of jaws to prevent slipping out of position, as the tool spreads be cautious as door will “spring” open suddenly
56
Forcible Entry Procedures Double Swinging Door – pry apart – remove bar – cut door panel – break glass Revolving Door – Collapse doors Panic proof Push/press door wings in opposite direction
57
Forcible Entry Procedures – Drop arm locate pawl press pawl to disengage it from arm push wing to one side – Metal-braced locate arms that look like gate hook with an eye force a side door
58
Forcible Entry Procedures Sliding Doors – Break glass Overhead Doors – pry upward at bottom – knock out panel and turn latch – cut opening in door and remove lock- “V” Cut – Knock out panel and pull motor release chain – Rolling steel doors are best opened by cutting it open with power saw
59
OBJECTIVE WINDOWS 2-11.6.2.

66
OBJECTIVE 2-11.6.3. CEILINGS
67
Forcible Entry Procedures Ceilings – Position yourself between area to be opened and an escape route – Break plaster in the area to be pulled – Use a pike pole to hook and pull lath & plaster, wire mesh, gypsum board, ceiling tiles – Pull down and away
68
CEILINGS Be advised, just as with our current fire stations, just because there is a drop ceiling or any other type, this does not mean that there is no other ceiling concealed beyond what you can see!
69
OBJECTIVE ROOFS 2-116.4.
70
Forcible Entry Procedures Roofs – Remove covers from existing structures on roof Skylights Scuttle hatches Monitors Ventilation shafts Stairway openings
71
ROOFS In some cases electrical wiring, gas lines, and other utilities may be located directly under rafters, you must use CAUTION!
72
Forcible Entry Procedures Flat Roofs – Determine where opening needs to be – Locate roof supports by sounding with axe – Mark location for opening by scoring a line on the roof surface with pick head of axe – Remove built up roof material by using pick head or halligan bar and move material out of the way – Never throw shingles off of the roof, there are people working below you
73
Forcible Entry Procedures – Cut wood decking diagonally alongside joist toward hole – Pry up roof boards
74
Forcible Entry Procedures Pitched Roofs – Locate where opening needs to made – Place roof ladder on roof s you are upwind from hole – Locate roof supports by sounding with axe – Mark location by scoring a line with tool – Rip off shingles or roofing felt sufficiently to permit initial cut to be made
75
Forcible Entry Procedures – Cut sheathing alongside rafter the distance required for hole – Cut opposite side of opening – Remove sheathing boards with a tool
76
OBJECTIVE 2-11.6.5. FLOORS
77
Forcible Entry Procedures Floors – Wood Determine location for hole Sound floor joists and find exact location Cut one side of finished floor by using angle cuts Cut other side of finished floor Remove flooring or floor covering with a tool Cut all sides of sub flooring using same angle cuts Remove boards from subfloor
78
FLOORS Joist usually run 16” on center. This means that it is 16” from the center of the board, to the center of the board
79
Forcible Entry Procedures Concrete Floors – Cut with jackhammer – Saws with masonry blades – Penetrating nozzles – Usually not done due to obvious labor and time involved
