Deck 8 Flashcards
When operating on a roof of questionable stability with hands tools or power saw, full use of the personal harness & LSR shall be used to limit travel of the operator of tool to a radius of no more than ______ ft from the basket.
10 feet. Create a bowline with a 15 ft loop.
Operating on peaked roofs can be difficult. To reach the ridge you would place the basket at a contact point on the roof and use a _________ to get to the ridge.
A hook ladder.
When pushing down ceilings from a roof of a taxpayer from the TL basket, you would consider using which 2 tools?
10 foot hooks or a portable ladder.
Venting a peaked roof with a power saw is done in 4 steps. There is a knockout cut, a cut perpendicular to the ridge pole, one parallel to the ridge pole and one running on an angle from the ridge pole down towards the gutter line. Put these cuts in the correct order.
- parallel to ridge pole 2. angular cut from cut #1 down towards gutter line 3. perpendicular to ridge pole 4. knockout cut. NOTE: make cut on the leeward side of the roof.
Victim removal via TL Basket. Fire in front of building. 1 ambulatory and 1 non-ambulatory. Give priority order and basket position.
Tip: Fat, Front, First. Fire in front, take the more complicated victim 1st. Set top railing level with sill. For an ambulatory victim, middle railing level with sill. Fire in the rear, make the easy grab 1st, then go back for the harder one.
Stokes basket removal via TL basket. Indicate the 3 ways to do this and which way is the preferred method? (5.2.1.D)
Vertical, diagonal (in basket), or horizontally lashed across the railings. Diagonal placement is easier and safer.
Fire building is heavily involved on several floors when the IC calls for a TL stream to be employed. How shall the stream be operated? (6.2.2)
Begin at the lowest level, working upward to the top floor or cockloft. NOTE: this is for a quick knockdown, not final extinguishment.
Heavy fire in the cockloft. How will the TL basket be positioned to operate? (6.2.3)
Position close to, and low in the window using stream to open up ceiling and expose the cockloft.
TRUE or FALSE The stream shaper on the Stang nozzle shall be used for all water applications at fires and/or emergencies. (6.2.7)
False: stream shaper is used only for straight stream nozzles. Remove the stream shaper for fog nozzles. Attach it directly to the looped barrel.
When operating a TL, how far shall the basket be kept from the building? (6.2.3.F)
Keep basket at least the same distance horizontally from building as it will be vertically below the top of the wall.
Water Delivery to TL:Best Source_______Supply base of TL with ______psiRelief Valve set at ______psiHow many water sources? _____Where is the pumper located? _______
Satellite Water Unit 200-250 psi250 psiGenerally only 1 source of waterPlace pumper as close as possible to TL
A relay pumper adjacent to TL should have in excess of _____ psi intake pressure with water flowing in order to operate in volume and deliver close to 250 psi.
In excess of 80 psi.
Which threads are stretched to the TL inlets? Male or female? (6.6.1.K)
Male threads
After heavy caliber streams have operated in a building, who’s responsibility is it to survey the building for run-off, structural damage or any other dangerous condition? (6.7.1)
The tower ladder officer will conduct the inspection.
Nozzle pressures should not generally exceed _____ psi.
100 psi.
