Answer 127

At least 5 rungs project above level of roof.

Question 128

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #141) When extending an aerial to the roof, the ladder should be extended so that at least 5 rungs project above level of roof. This allows for (why):

Answer 128

* Allows for → greater visibility of escape route when conditions on rood start to deteriorate. In addition, * Extra projection allows member to maintain firm handhold at normal standing position while mounting or dismounting the ladder.

Question 129

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #142) When raising an aerial to the roof, the ladder should be extended so at least 5 rungs project above the level of the roof (reasons for are on previous notecard). Ladder itself should maintain ___ from the bldg:

Answer 129

An inch or 2 out from bldg

Answer 130

* Avoids placing strain on parapet walls. * Allows truss construction of ladder to perform as designed. * (when ff’s wt is applied to ladder, beam will just rest of edge of roof)

Question 131

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #144) Fig. 7-21: Aerial ladders should always be extended at least 5 rungs over the roof line, why:

Question 132

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #145) When positioning aerial – important to make sure ladder is placed as ___ as to the bldg as possible.

Answer 132

* Square | * (if placed at an angle to bldg, 1 beam of ladder will contact bldg 1st)

Question 133

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #146) Positioning aerial – important to make sure ladder is placed as square to bldg as possible. If ladder placed at an angle, 1 beam of ladder will contact bldg 1st. As climbing FF’s weight approaches tip, ladder will twist until other beam also rests on the edge of the roof. This is dangerous for 2 reasons:

Answer 133

* The twisting is a severe torsional load that can lead to ladder failure. * As ladder twists, (far beam) pulls other beam (near beam) to the side it’s twisting toward → ladder can slide

Question 134

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #147) To avoid twisting and ladder failure – position apparatus so:

Answer 134

* Turntable is inline w/ objective, then → | * Then rotate ladder until it’s perpendicular to the bldg.

Question 135

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #148) Fig. 7-23: Failure to position an aerial square to the building leads to:

Answer 135

* 1 beam contacting the bldg 1st. * This causes the ladder to slide sideways along the parapet wall. * (potentially causing ladder failure)

Question 136

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #149) When placing platform on roof – Member in basket can place it for the best location. If roof has no parapet wall, its best to place the basket (how):

Answer 136

Over the building - so that its just resting on the roof. | this allows FFs to step directly through platform gate onto the roof

Question 137

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #150) If bldg has parapet of moderate height (3 – 6’), best placement for basket is:

Answer 137

Place top rail of platform basket just slightly above the top of parapet. (this makes it easier for M’s climbing in or out of the basket)

Question 138

Ch. 7: Norman – Ladder Company Operations Section: Aerial Devices (NC #151) Best placement of platform on bldg with unusually high parapet wall (more than 6’) is:

* Get to the fire, * Search for & cut off any extension, * Search for & remove any victims.

Question 142

Ch. 7: Norman – Ladder Company Operations Section: Vent, Enter, Search – VES (NC #155) VES is recommended more than the all-interior approach because:

Answer 142

The escape route is always on the outside of the building – which isn’t as likely to be cut off by extension.

Question 143

Ch. 7: Norman – Ladder Company Operations Section: Vent, Enter, Search – VES (NC #156) VES – elevating platform is clear choice over an aerial ladder. Because:

Answer 143

* Basket is safer to work from when venting a window, * If victim found, especially unconscious or disabled – its safer, faster & more efficient to take them down than an aerial, * Basket is a better area of refuge – if conditions worsen, can quickly pile into basket.

Question 144

Ch. 7: Norman – Ladder Company Operations Section: Vent, Enter, Search – VES (NC #157) Positioning a basket to a window requires a different technique from placing it on the roof. First, most platforms have ___ mounted on the center of the basket:

Answer 144

* Master stream nozzle | * (this can impede access to the basket at the center).

Question 145

Ch. 7: Norman – Ladder Company Operations Section: Vent, Enter, Search – VES (NC #158) M/S nozzle can impede access to basket at the center, but front corners of basket are relatively unobstructed. When positioning elevating platforms for rescue, spot basket how:

Answer 145

* As close to bldg as poss. * In-line w/ the window – this assures shortest distance of travel & places front corner of basket at the window. * Top rail of basket is level w/ windowsill * (Unless lineup is perfect - gates on basket can be disregarded – they’re narrow & aligning takes too much valuable time)

Question 146

Ch. 7: Norman – Ladder Company Operations Section: Vent, Enter, Search – VES (NC #159) Fig. 7-25: When positioning platforms for rescue, spot the ___ in line with the objective:

Answer 146

Makes it easier to enter the basket (& keep the people in the basket away from most of the smoke & heat emanating from the window).

Question 148

Ch. 7: Norman – Ladder Company Operations Section: Vent, Enter, Search – VES (NC #161) Elevating platform gates – many of the gates only open ___, reducing the space available inside the basket:

Answer 148

Inward

Apparatus may be too close to swing ladder or boom to lower floors – where it may be needed most.

Question 158

Ch. 7: Norman – Ladder Company Operations Section: Vent, Enter, Search – VES (NC #171) The particular perfect distance for an aerial device to obtain its maximum scrub area varies depending on:

Question 164

Ch. 7: Norman – Ladder Company Operations Section: Vent, Enter, Search – VES (NC #177) When positioning midship-mounted devices, the best scrub area is obtained by placing the apparatus:

Answer 164
