A radius of 10 feet
When using the TL for ventilation purposes to the roof what tools shall be placed in basket?
Axe
Halligen
saw
6’ hook and LSR in basket
When using the LSR on roof of questionable stability to limit travel how do u secure it to TL?
Rope shall be tied to a substantial part of basket use a bowline with 15 foot loop and personal harness
Note pertains to a isolated roof where ventilation cannot be performed from adjacent troop without steeping fully onto roof of fire building
Backup man will hold rope securely
When using TL basket for rescue purposes the basket should be lined up to objective by initially elevated too
Middle basket railing level with window ledge or level with top railing of fire escape
When rescuing incapacitated or obese victims you should line up TL basket
Top railing level with sill or top rail of fire escape
When operating TL stream into cockloft to extinguish fire you should start stream where then move to where
Work stream from party wall balcony of most serious exposure to center than from other party wall of other exposure toward center or roof opening
When positioning the basket of TL for overhauling purpose where should the railing be placed ?
Top of basket railing should be slightly below work area
TL ladders are not designed to operate with jacks and outriggers down on one side
Exception:
If apparatus not level
Lower jacks and outriggers on low side first
Them jacks and outriggers on high side until unit is level as possible
If member decides to abort setting upTL then he must
- Properly place all outriggers and jacks for operation
2. Return all outriggers and jacks to the pre-setup position
Floor area of TL basket is
Approximately 15 sq ft
Boom rotation permits water system coverage of
360 degrees
Water system hook ups for TL
3x3 gated Siamese on left side
4- 1/2 inlet n right side
When making reference to movement of the boom it is in reference to the pedestal or basket
Pedestal
Rotate left is to pedestal mans left
Intercom
Most effective way to communicate
Check daily prior to use
If intercom check is negativf than use HT
HT also used if basket man operating alone for cd ting or search purposes as means of coordinating with interior forces or if he leaves basket
Detailed members can operate on pedestal only if
Presently assigned to TL
Qualified chauffeurs/tiller man ( school trained )
If using LSR to secure oneself to substantial part of basket
For a one foot in diameter loop
Bowline on bit
Life belt or personnel harness into loop
If member leaves basket for search or roof ops do not move basket unless
Members are advised
This members give approval or
Visible life hazard
Unit Commanders shall have members trained in following
Place TL in PTO and set appAratus for boom ops
Operate basket controls and pedestal controls and console
Control stang
Be familiar with basic emergency procedures
Assume position of pedestal man
Stretch lines and reposition apparatus

70’
75 degrees
The basket while touching a point 32 feet horizontally from center of turntable can reach a basket floor elevation of
65 feet
Total scrub
Front of building 60 feet high and 50 feet wide
Lower 3 floors on building g 100 foot frontage
Stub area is
Approximately 7750 square feet with turntable 32 feet from building with cab 15 degree angle from building line
Basket can reach points how many feet below grade
10 feet below grads
Grades up to what percent shall be considered level ground
4 percent
Positioning on hill you should position apparatus so thst boom works on
Uphill direction
If possible you should face apparatus down hill if facing downhill place turntable ___the objective and if facing uphill place turntable ______ objective
Downhill past objective
Uphill before objective
Maximum slope for TL op
15 degree grade
Difference in 5 1/2 feet from front to rear is approximately 15 percent slope
Recommended work uphill
Boom rated at what capacity according to TL ops
1000 lb capacity
During winter ops the boom of thd TL should be raised to what angle to drain
60 degree angle
After boom bed than remove drain plugs on waterway
When using a portable ladder from a TL basket to extend the height capability you should sit what type of ladder
20 ft combo ladder
May use 25 foot or 35 foot extension ladder (only if no alternative
The basket ladder securing ladder is a ______ foot of 1/2 inch rope which has a _____ at what end … This rope is secured to the ladder with rope going threw which rung of the ladder ?
15 foot
Hose strap hook
6th rung from butt
In attempt to reduce lateral movement when using a portable ladder in the TL bucket, the portable ladder can be raised in line with the boom. If this is done you secure the ladder with rope to where?
The Two rear main posts
Note : normally the rope with hook is attached to stang riser and other end of rope is. Attached to horizontal section of waterway or rear basket main post
What’s the max amount of members allowed in basket when using a portable from basket
3 members
If TL is special called for use of elevated streams, you as officer should expect what to be set up prior to your arrival
Access cleared
Supply source designated
May have supply lines stretched already
Nozzle pressures for TL should not exceed
100 psi
Notes about raising a portable ladder from a TL basket
- No time should beams of ladder touch the basket railing
- Tips of both beams of portable ladder must rest on building (cantilever forbidden)
- Ropes shall not be secured to TL gates or railings
- No more than 3 men in basket
Utilization of power saw for basket
Basket as close to ridge pole as possible
Saw started in basket and then held outside basket
Kept outside until shut off
Use safety belt or LSR tied to substantial part of basket (not Railing )…loop of bowline large enough to allow member to reach edge of basket platform
One foot on roof one in basket
IST cut parallel to ridge pole.. second cut parallel to first forming a triangle third cut at bottom of triangle perpendicular to cut one and two and forth cut knock out cut
Breaching walls
Power saw with proper blade
Electric or pneumatic hammers may be used
Cuts In brick triangular with vertex angle up
IST and second cuts at brickwork
3 cut at mortar joint
Cut large enough to fit saw in
When a building is heavily involved in fire in serval floors, heavy stream delivery should generally start where
Lowest floor and work upward
When securing the stang nozzle to the TL basket which of the following is not considered an acceptable method
- Securing nozzle to railing of basket
- Securing to stang base waterway
- Or to one of main posts at rear of basket
1 securing nozzle to basket railing
Water delivery to TL points
- Satellite best source of supply with largest caliber hose
- Supply at base of TL at 200 psi to 250 psi
- Relief valve at 250 psi
- Generally only one source
- Conventional pumpers as close as possible to TL
- Relay may take from more than one source
- Relay pumper next to TL should have in access of 80 psi on intake with water flowing so delivery in volume to get 250 psi
- Shut down at pumper not TL
- Do not use TL as standpipe
10 stretch male of 3 1/2 to TL when possible - Water supply to pumper from pumper other than one supplying first due companies if possible
It is responsibility of whom to survey the building after the TL stream is shut off so that the stability of the building can be assessed
Officer of TL
When taking up when shall you open the hydraulic pressure relief valve on TL
After. OOD is bedded and jacks and outriggers are seated
If for any reason the limit switch finger on TL sticks you should
Move with 6 foot hook and then call fleet maintenance
