PART I FFP LADDERS 6:

Transcription

1 PART I FFP LADDERS 6: 1. The Tower Ladder chassis is supported at six points while the boom is in operation, i.e., two hydraulically operated jacks are located at the front and two at the rear of the vehicle (total of four), and two out-rigger type jacks in the middle of the apparatus. All supports have a direct frame attachment to bypass the apparatus suspension and provide a rigid operating base. Please choose an incorrect point about the jacks and outriggers on a Tower Ladder? (Ladders 6, section 2.1.4) A) All jacks and outriggers must be lowered until each reaches the end of its stroke before raising the boom. B) Tower ladders are not designed to operate with outriggers and jacks down on one side only. Exception: If apparatus is not level, lower the jacks and outrigger on the high side first, then the jacks and outrigger on the low side until unit is level as possible. C) Raising the high side fully before raising the low side, or raising only one side when on level ground, can cause damage to the suspension system. D) A mechanical lock is also provided at each jack and outrigger. These locks (pins) must be inserted manually. 2. To judge that Tower Ladder outriggers will clear all obstructions, a may be used as a gauge. Please fill in the blank? (Ladders 6, section 2.1.7) 3. Any member operating a tower ladder must personally verify the placement of all outriggers and jacks prior to raising the boom from the bedded position. If a member commences to set up a tower ladder apparatus for an operation and then decides to abort the operation, the member must: Please choose which item or items are correct from the list below? (Ladders 6, section ) A) Properly place all outriggers and jacks for operation. B) Return all outriggers and jacks to the pre-setup position. 4. The Tower Ladder basket is constructed of alloy aluminum and has a floor area of approximately square feet. Please fill in the blank? (Ladders 6, section 2.3) A) 5 B) 10 C) 15 D) 20 HW #8 - Spring

2 5. Please choose a correct point(s) about the Tower Ladder dead man control from the list below? (Ladders 6, section 2.4.5) A) Depressing the foot pedal at the pedestal activates the system and the engine throttle control. B) Depressing the foot pedal at the pedestal also deactivates the basket controls by activating the hydraulic system in case of electrical failure. C) The release of the "deadman" control (foot switch on pedestal) will immediately halt all boom movement. D) All of the above. 6. Please indicate if you agree or disagree with the below paragraph? (Ladders 6, section 2.6.1) When no other solution is possible, members may escape from the Tower Ladder basket by means of the fixed telescoping ladder mounted on top of the boom sections or by the life saving rope in conjunction with the Personal Harness, which ever is most appropriate for the situation. A) Agree or D) Disagree 7. The Tower Ladder is provided with an intercommunication system (intercom), allowing for basket to pedestal communications and vice versa, however handi-talkies are the most effective means of communications between basket and pedestal. Please indicate if you agree or disagree with the above paragraph? (Ladders 6, section 2.8.1) A) Agree or D) Disagree 8) The following terms shall be used when transmitting orders from the basket to the pedestal man: (Ladders 6, section 2.8.2) A) "EXTEND BOOM" - Reach out with boom. B) "RETRACT BOOM" - return outstretched boom. C) "RAISE BOOM" - Increase angle of elevation D) "LOWER BOOM" - Decrease angle of elevation E) "BOOM LEFT" - rotate boom to basket man's left. F) "BOOM RIGHT" - Rotate boom to basket man's right. Please choose the incorrect point(s) from above? HW #8 Spring

3 9. Please choose an incorrect Tower Ladder (TL) procedure from the list below? (Ladders 6, section 2.8.4, 2.8.5, 2.8.7, & 2.9.2) A) Since the pedestal controls allow smoother movements, the pedestal man should, in most cases, perform delicate operations if visibility permits. B) The intercom between pedestal and basket should be used for operational control of the apparatus to achieve the desired coordination. C) During the daily check of the apparatus and at the initial stages of placing the TL into operation, a test of the intercom system shall be made. If results are negative, members shall rely on Handie-Talkies for communication from pedestal and basket. D) Detailed members cannot operate on the pedestal unless they are presently assigned to an Aerial or Tower Ladder Unit or are a qualified Chauffeur-Tillermen (QCT, School Trained). 10. Please choose an incorrect Tower Ladder (TL) point from the list below? (Ladders 6, section 3.1.3, 3.1.4, & 3.1.5) A) "Scrub area" is defined as that area of a building wall which can be touched by the basket. B) The apparatus should always be parallel to the building. C) Occasionally the scrub area of the bucket will be reduced by the cab of the apparatus. This condition can be corrected by parking the apparatus with the front end angled about 15 degrees from the building line. D) Positioning at a corner building affords coverage on two fronts. E) Placement of TL shall be made to retain as much effective operating area of the basket as possible on both fronts of the building. 11. Where the ground is of doubtful stability, such as vacant lots or other unpaved areas that may have hidden voids, and plank pads for Tower Ladder outriggers are deemed not substantial enough, it may be more advantageous to position the apparatus or nearly to the fire building. Please fill in the two blanks? (Ladders 6, section 3.1.6) A) perpendicular / perpendicular B) parallel / parallel 12. During all operations, the Tower Ladder pedestal member shall: Please choose the incorrect procedure from the list above for the pedestal member?

B) Maintain and monitor Handie-Talkie communications and relay orders and pertinent information to basket via intercom. C) Be prepared to take over controls should basket controls become erratic or inoperative. D) If member(s) leave the basket for search or roof operations, the pedestal member shall not move the boom unless member(s) are advised of his/her intentions and they in turn give approval, no exceptions.

7 ANSWERS 1. Answer: B = Tower ladders are not designed to operate with outriggers and jacks down on one side only. Exception : If apparatus is not level, lower the jacks and outrigger on the low side first, then the jacks and outrigger on the high side until unit is level as possible. 2. Answer: 6-ft hook 3. Answer: A or B is correct. 4. Answer: C 5. Answer: D = Note: The use of the platform control switch is necessary whenever members or civilians enter or leave elevated basket. This is to insure against movement of the basket by accidentally touching the platform control handle. 6. Answer: A 7. Answer: D = The Tower Ladder is provided with an intercommunication system (intercom), allowing for basket to pedestal communications and vice versa, which is the most effective means of communications between basket and pedestal. 8. Answer: E = "BOOM LEFT" - rotate boom to pedestal man's left. F = "BOOM RIGHT" - Rotate boom to pedestal man's right. Note: In some models, the basket control man faces the opposite direction in relation to the pedestal man. It is for this reason that the reference point is the pedestal and not the basket position. 9. Answer: D = Detailed members cannot operate on the pedestal unless they are presently assigned to a Tower Ladder Unit or are a qualified Chauffeur-Tillermen (QCT, School Trained). 10. Answer: B = Generally the apparatus should be parallel to the building. 11. Answer: A 12. Answer: D = If member(s) leave the basket for search or roof operations, the pedestal member shall not move the boom unless member(s) are advised of his/her intentions and they in turn give approval, or a visible life hazard should occur. 13. Answer: C = TL scrub area covers the front of a building 60 feet high and 50 feet wide, and will cover a 100 foot frontage on the lower three floors of a building. 14. Answer: E 15. Answer: A = Position apparatus parallel to the direction of slope so that boom operations will be in the "up-hill" direction. 16. Answer: C 17. Answer: C = Note: Confine Space - states at least 800 LBS. (TL figure 6 asked on 2002 Lts test.) 18. Answer: All of the above 19. Answer: A 20. Answer: D 21. Answer: D = Back-up man takes a firm hold on the operator's Personal Harness or Life Belt. 22. Answer: A = Note: The size of the cut will depend on the reach of the operator. He shall never over-extend himself. Re-position basket if larger opening is necessary. HW #8 - Spring
