Doors
Opening DoorsOpening Doors
TRY BEFORE PRYIf door is locked
– examine construction– determine method of operation– examine lock– Force? Find other methods of entry?– Use easiest, quickest, and least damaging
method.
Forcible Entry ProceduresForcible Entry ProceduresDoors
– 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
Forcible Entry ProceduresForcible 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
Forcible Entry ProceduresForcible Entry ProceduresBreak lockStopped 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
Forcible Entry ProceduresForcible Entry Procedures
– With full bite behind door pry door away from jamb until bolt passes keeper
Forcible Entry ProceduresForcible 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
Forcible Entry ProceduresForcible 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
Forcible Entry ProceduresForcible Entry ProceduresDouble Swinging Door
– pry apart– remove bar– cut door panel– break glass
Revolving Door– Collapse doors
Panic proof Push/press door wings in opposite direction
Forcible Entry ProceduresForcible 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
Forcible Entry ProceduresForcible 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

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
CEILINGSCEILINGS
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!

In some cases electrical wiring, gas lines, and other utilities may be located directly under rafters, you must use CAUTION!
Forcible Entry ProceduresForcible Entry ProceduresFlat 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
Forcible Entry ProceduresForcible Entry Procedures
– Cut wood decking diagonally alongside joist toward hole

Check wooden components– cracks– rot– splinters
Check metal components– cracks– rust– chips
InspectInspect
Belts for cutsCheck for obvious damageCheck cutting surfaces for sharpness
MaintenanceMaintenanceWood surfaces should be coated with boiled
linseed oil to prevent drying outFiberglass should be patchedMetal surfaces should be lightly oiledPower tools should be serviced regularlyAxe heads should be checked for
– body thickness– sharpness of blades
MaintenanceMaintenanceWood handles
– Heads on tight– Do not paint
Cutting edges– No nicks– File edges, but not to a razor sharp state
Metal surfaces– No rust– Oil it– NO paint
MaintenanceMaintenance
– Keep free of burrs
Power equipment– service regularly– check cords if electric– follow manufactures recommendations for
upkeep
