15

WHEN ARRIVING AT A FIRE/EMERGENCY HOW FAR SHOULD YOU POSITION YOUR RIG FROM THE REAR OF A LADDER APPARATUS TO ACHIEVE CLEARANCE FOR THE 20FT STRAIGHT AND 35FT EXTENSION LADDERS?

20 FT TO THE REAR OF THE LADDER APPARATUS

8.1.1 20 foot straight and/or 35 foot extension ladders are carried in the internal slide-in
racks on many ladder company apparatus. If another apparatus arriving at a fire
or emergency is positioned closer than 20 feet to the rear of the ladder apparatus,
the 20 foot straight or the 35 foot extension ladder cannot be removed from these
racks due to insufficient clearance.

16

WHAT IS THE CLIMBING ANGLE FOR A GROUND LADDER?

APRX. 65-75 DEGREES

8.4.1 The 65-75 degree angle allows the ladder to provide its maximum strength and
best service.
8.4.2 An angle steeper than 75 degrees increases the chances of the climber falling off
and sustaining injuries.
8.4.3 Ladders angled less than 65 degrees require a reduction in maximum loading.

-BOTH HANDS PLACED AGAINST AND GRASP BEAMS TO AID IN STEADYING LADDER
-IF MEMBER ON LADDER IS WORKING OFF ON SIDE OF THE LADDER, BUTT MAN REPOSITIONS HIS LEFT FOOT FROM CENTER OF THE BOTTOM RUNG TO THE SIDE OPPOSITE FROM WHICH THE FF IS WORKING AND PLACES HIS FOOT NEXT TO THE BEAM

24

LIST THE STEPS TO PROPERLY CLIMB A PORTABLE LADDER:

•Climb on the balls of the feet near the arch, left and right of the center line, up and down the ladder.
•Undersides of the beams are grasped with the hands.
•Eyes look up or forward.
•If a tool is carried, it should be balanced in the carrying hand, which holds onto the side of the beam.
•Do not carry the tool close to the body or inside the ladder over the rungs because of the danger to the butt member below should the tool be accidentally dropped.

25

LIST THE STEPS TO CLIMBING A PORTABLE LADDER DURING FREEZING WEATHER WHEN ICE FORMS ON THE LADDER:

•Position the rung of the ladder under the arch of the boot, next to the heel.
•Position the feet on the rungs directly next to the beams
•Hands remain on the undersides of the beams. Should a member slip while climbing, they should immediately pull themselves into the ladder and regain their footing.

26

DESCRIBE THE LEG LOCK:

•The leg performing the locking maneuver is opposite the working side.
•To perform the leg lock, the locking leg is placed over and under the rung that is two rungs above the one on which the member is standing.
•The instep of the locking leg is placed on the beam of the ladder opposite the member's working side.
•The arch of the foot on the rung is placed against the other beam.
•The butt firefighter moves their foot from the center of the bottom rung of the ladder to the side opposite the one from which the firefighter is working, and places their foot next to the beam.

27

A MEMBER DRILLING ON THE "LEG LOCK" MANEUVER WOULD BE CORRECT IF HE STATED THAT THE LOCKING LEG IS PLACED OVER AND UNDER A RUNG THAT IS _____ RUNGS ABOVE ON WHICH THE MEMBER IS STANDING.

2 RUNGS ABOVE

8.2.1 The Leg Lock:
•The leg performing the locking maneuver is opposite the working side. For example, if the member wants to lean to the right and vent a window, they will lock their left leg on the ladder.
•To perform the leg lock, the locking leg is placed over and under the rung that is two rungs above the one on which the member is standing.
•The instep of the locking leg is placed on the beam of the ladder opposite the member's working side. (See Figure 5).
•The arch of the foot on the rung is placed against the other beam.

28

DESCRIBE BRIDGING A FENCE WITH PORTABLE LADDERS:

•One ladder is placed against the fence at the proper climbing angle and butted by a member.
•One member ascends the ladder to the point where the top of the fence is at about waist level.
•The butt end of the second ladder is passed to the member on the first ladder. He/she then places one beam of the second ladder on top of the fence. The second ladder is slid out a sufficient distance, pivoted downward from the fence top, and lowered to the ground.
•The second ladder is adjusted to provide a proper climbing angle.
•The adjacent beams of the two ladders are tied together securely where they intersect, to prevent ladder movement during use.

29

L12 WORKED AN OLT TENEMENT (W/O A FRONT FIRE ESCAPE) CELLAR FIRE & THE MEMBERS ARE GOING OVER THE JOB, SPECIFICALLY PORTABLE LADDER PLACEMENT. ACCORDING TO LADDERS 1 WHERE SHOULD PORTABLE LADDERS BE PLACED ON THIS BUILDING DURING THIS FIRE?

ADJACENT TO AND ABOVE THE FIRE AREA


10.1 Tenements without front fire escape.
•When the fire is in the cellar, 1st floor and/or 2nd floor, raise the portable ladders adjacent to and above the fire area, even if the aerial ladder will be required on the upper floors.

30

L12 HAS BEEN BUSY THE WINTER AND CAUGHT ANOTHER OLT JOB. THIS TIME THE BUILDING HAD A FRONT FIRE ESCAPE. THE CAPT. OF L12 WAS REVIEWING THE FIRE TACTICS AT THIS PARTICULAR JOB, SPECIFICALLY PORTABLE LADDER PLACEMENT. WHERE SHOULD PORTABLE LADDERS BE PLACED AT THIS JOB?

•PORTABLE LADDERS RAISED TO FIRST FIRE ESCAPE BALCONY OPPOSITE THE DROP LADDER
•IF REQUIRED ANOTHER PORTABLE LADDER SHOULD BE RAISED TO THE SECOND BALCONY (PICTURE SHOWS THIS LADDER ON DROP LADDER SIDE)

10.1
Tenements and multiple dwellings with front fire escapes.
•Fire escapes often become overcrowded when there is a fire anywhere within the building. Under these conditions, a portable ladder should be raised to the first balcony at a point opposite the drop ladder. If more relief for the fire escape is required, another portable ladder should be raised to the second balcony.

31

LADDER 12 IS DOING IT, THE COMPANY CATCHES YET ANOTHER OLT JOB THIS WINTER. THIS SPECIFIC BUILDING HAD PARTY WALL BALCONYS. IF FIRE HAD EXTENDED TO THE ADJOINING BUILDING ELIMINATING THE SECONDARY MEANS OF EGRESS, OCCUPANTS MAY BECOME TRAPPED ON THE FIRE ESCAPES. WHAT LADDER COULD L12'S ROOF OR OV FIREFIGHTERS USE TO GAIN ACCESS TO THESE TRAPPED PEOPLE N THE BALCONIES?

12' HOOK LADDER

++Because of its portability the 12' hook ladder may be used to gain access to the various balcony levels by the Roof or OV firefighters for search and rescue. The ladder may be brought to the rear yard as mentioned above, or brought to the roof via Aerial, Tower Ladder or utility rope and lowered to the top balcony.++

32

L132 OPERATED AT A BROWNSTONE FIRE IN CROWN HEIGHTS, THE OVM FF PLACED A PORTABLE LADDER TO THE SMALL WINDOW LOCATED ABOVE THE MAIN ENTRANCE, DID HE OPERATE CORRECTLY?

NO

10.2
•Placing a portable ladder at the window of the small room over the front entrance door will be difficult because of the long, high stoop, which may interfere with firefighting operations. Consider placing the ladder at the adjoining window to gain entrance to this small room.

33

TRUE/FALSE

AT BROWNSTONE BUILDING FIRES PORTABLE LADDERS BROUGHT TO THE REAR OF THE BUILDING AND PROPERLY POSITIONED ARE SAFER THAN LSR OPERATIONS.

TRUE

++Portable ladders transported to the rear of the building and properly positioned are safer than a life saving rope rescue.++

34

IF A FF STATED THAT AT BROWNSTONE FIRES, TRANSPORTING A PORTABLE LADDER THROUGH THE PARLOR FLOOR OF THE FIRE BUILDING WILL ALWAYS GET YOU ACCESS TO THE REAR, WOULD YOU AGREE?

NO

++In most cases, taking the ladder through the second floor (parlor floor) of an adjoining brownstone and passing it out the rear window to another member in the yard below is faster than using the fire building.

Note: In a brownstone, it is important to take the ladder through with the butt facing the rear of the building. In a row frame, transporting a ladder through the interior of the building to the rear is generally less complicated because there are front and rear doors or window entries at ground level.++

35

FF TORREZ IS CONDUCTING A DRILL ON BROWNSTONE BUILDINGS WITH THE JR. MEN AND SAYS THAT THE CORRECT WAY OF TRANSPORTING A PORTABLE LADDER THROUGH A BROWNSTONE BUILDING WOULD BE TO CARRY THE LADDER WITH THE TOP SECTION FACING THE BUILDING. SHOULD YOU CORRECT HIM?

YES

10.2
Note: In a brownstone, it is important to take the ladder through with the butt facing the rear of the building. In a row frame, transporting a ladder through the interior of the building to the rear is generally less complicated because there are front and rear doors or window entries at ground level.

36

39

DESCRIBE THE STEPS TO VENTING A GROUND FLOOR LEXAN WINDOW WITH A PORTABLE LADDER:

•Remove the exterior screen.
•Place the butt of the ladder on the Lexan window in the corner adjacent to the window frame.
•Three or four members apply a gradual leaning pressure against the window until it is forced inward.
•If a section of window snaps off, continue forcing around the window perimeter until a sufficient opening has been made.

40

WHAT IS THE PROPER POSITION OF A PORTABLE LADDER WHEN A FF IS ATTEMPTING TO VENT A WINDOW WITH BEING ON THE LADDER?

•LADDER IS UPWIND FROM WINDOW TO BE VENTED
•TIP OF LADDER, IF POSSIBLE, SHOULD BE LEVEL WITH OR HIGHER THAN THE TOP OF THE WINDOW

6' HOOK

43

WHAT IS THE PREFERRED LADDER WHEN PLACING A LADDER OVER BURNT OUT STAIRS?

EXTENSION LADDER

++10.3.4 Portable ladders may be placed over weakened, damaged or burnt-out stairs in order to safely gain access to upper stories of a building. The preferred ladder for this is the extension ladder rather than a straight ladder.++

44

TRUE/FALSE

WHEN USING AN EXTENSION LADDER TO BRIDGE A GAP, IT IS ADVISABLE TO FULLY EXTEND THE LADDER.

FALSE

10.3.7 Portable ladders used in bridging operations can span courts, alleys, shafts and similar openings between floors and roofs. Extension ladders must be used only in the nested position when bridging.

45

TRUE/FALSE

When a ladder has been positioned and used by a member to gain entry to a fire building, there is the possibility that he/she will also need it as a means of retreat. The ladder is expected to be there. Therefore, do not move or reposition a ladder used in this manner except if it is necessary to use the ladder for rescue. Members operating in the area the ladder was used to access should be notified regarding its repositioning. The ladder should be returned to its original location or replaced with another ladder as soon as possible.

TRUE

46

LIST SOME GOOD PORTABLE LADDER SAFETY POINTS:

•Extension ladders should never be used upside down, that is, with the round ends down.
•When an extension ladder is raised, the halyard shall be tied off to the lower section of the ladder as a safety measure and prevent the ladder locks from accidentally unlocking by a pull on the rope.
•Ladders should never be placed against window panes, window sashes, or loose boxes, barrels, or other surfaces that may break or collapse.
•Do not climb higher than the third rung from the top on either straight or extension ladders.
•Never maintain a defective ladder in service. When a defect in a ladder is found during an in-quarters inspection or damaged at a fire, remove the ladder from service and notify the Fire Tools and Equipment Unit for collection, repair or replacement.
•Both metal and, under certain conditions, wooden portable ladders can conduct electricity.
