3 I INTRODUCTION A. This manual has been prepared by the Florida Department of Transportation District Two Structures and Maintenance Office to describe the duties and responsibilities of bridge tenders operating drawbridges in FDOT District Two. It is intended to serve as a guide to assist bridge tenders in understanding their role in the proper and safe operation of drawbridges. B. The State of Florida has entrusted to the bridge tender thousands of lives and a valuable piece of machinery, the proper operation and care of which is of primary importance to the people using the highways and waterways in the State of Florida. It is the bridge tender s responsibility to conduct all operations of the bridge in strict accordance with the regulations of the United States Coast Guard and with applicable Department procedures; to adhere to the policies and instructions as given in this manual, which may be supplemented by additional instructions from the supervisor; to take such actions as will be required to maintain safe bridge operation; to maintain cleanliness on the bridge and in the bridge tender house; and to call local police when necessary to maintain order on or near the bridge. II JURISDICTION A. Primary jurisdiction to regulate drawbridges over the navigable waters of the United States is vested in the United States Coast Guard. The regulations are presented in the Code of Federal Regulations, Title 33 Navigation and Navigable Waters, hereinafter referred to as CFR 33. Such bridges owned and operated by the State of Florida have been constructed and are maintained and operated by permit from the United States Coast Guard. Rules for the bridge tender to operate the bridges will be contained in the Manual and may be periodically amended. B. If anyone knowingly fails to comply with any regulation or rule issued or order given under the provisions of CFR 33, or knowingly obstructs or interferes with the exercise of any power conferred by CFR 33, he/she may be punished by imprisonment for not more than ten (10) years and may, at the discretion of the court, be fined not more than $10, The bridge tender is advised to be knowledgeable of the rules and regulations in CFR 33. It is the responsibility of the bridge tender to ask his/her supervisor about any rule or regulation that he/she does not thoroughly understand. D II BRIDGE TENDING MANUAL Page 2 EXHIBIT B

IV SIGNALS A. GENERAL 1. The operator of each vessel requesting a drawbridge to open shall signal the bridge tender and the bridge tender shall acknowledge that signal. The vessel operator may repeat the signal until the bridge tender has acknowledged in some manner. The vessel should not approach the bridge until an acknowledgement is received from the bridge tender. The bridge tender shall complete the BRIDGE TENDERS REPORT ON UNAUTHORIZED APPROACH OF VESSELS if in his/her opinion the vessel has violated this rule. 2. The authorized signal devices and order of preference to be used to request an opening and to acknowledge a request shall be communicated by VHF radio, sound signals or visual signals. Whatever signals are used, they must be sufficient to alert the person being signaled. 3. All acknowledging signals given by the bridge tender shall follow the requesting signal by no more than 30 seconds. D II BRIDGE TENDING MANUAL Page 9 EXHIBIT B

11 B. VESSEL SIGNALS FOR BRIDGE OPENING REQUEST 1. Communication by VHF Radio. If the request for bridge opening has been made by VHF Radio, the response will normally be completed by this method in compliance with the following guidelines: GUIDELINES FOR OPERATION OF VHF MARINE RADIO!!!SPEAK SLOWLY CLEARLY CALMLY!!! a) NORMAL OPERATION 1. Make sure radio is on at all times and monitoring Channels 9 and Upon hearing a boat operator trying to contact the bridge, the bridge tender should pick up the microphone, press the microphone button and say: Affirmative, (calling boat name) this is the (bridge name) bridge, Switch to Channel 9 (working channel number). 3. The bridge tender should then tune the VHF marine radio to the working channel stated in Number 2 above. 4. Upon hearing the boat operators request for a boat opening, the bridge tender has two basic options. They are: a. Pick up the microphone, press the microphone button and say: Affirmative, (calling boat name), the (bridge name) bridge will open for your passage. The bridge tender must then immediately start the process of opening the bridge. b. If the bridge tender must delay the opening for any reason, he/she must pick up the microphone, press the microphone button and say: Negative (calling boat name) bridge cannot open for (time) because (state the reason the bridge cannot be opened). If additional clarification is needed, the bridge tender may continue with a very brief conversation. Care should be exercised to prevent a confrontational type conversation. 5. At the end of either conversation, (a) or (b), as soon as the boat operator acknowledges receipt of the information, the bridge tender should pick up the microphone, press the microphone button and say This is the (bridge name) bridge, monitoring Channels 9 and 16 and then switch the radio back to Channel 9 and 16. If the vessel is passing under the bridge, the bridge tender must monitor the working channel until the vessel has cleared the draw span. D II BRIDGE TENDING MANUAL Page 10 EXHIBIT B

12 b) ABBREVIATED OPERATION The abbreviated form of operation can only be used when the following two conditions are met: 1. The boat operator requests the bridge opening during his/her first radio transmission while trying to make contact with the bridge tender. For example: Ortega River Bridge, This is the Blue Duck, WA1234, requesting a bridge opening. 2. The bridge tender determines that the bridge can be raised immediately without delay. If both conditions are met, the bridge tender may pick up the microphone, press the microphone button and say: (Boat name) this is the (bridge name) bridge, Wilco, the bridge will be opened for your passage, Out. This one statement terminates the radio conversation. If either the boat operator or bridge tender want any further conversation, they must switch over to some other proper working channel. In the event that contact cannot be maintained, sound or visual signals will be used. Channel 16 shall always be monitored but should not be used for communications, use the bridge operating channel (9) instead. B. SOUND SIGNALS Sound signals shall be made by activating the horn mounted on the bridge tender house. When the bridge can be opened immediately, the sound signal to acknowledge a request to open the bridge is one prolonged blast (approximately 4-6 seconds duration) followed by one short blast (approximately 1 second duration). When the bridge cannot be opened immediately, or is open and must be closed promptly, the sound signal to acknowledge a request to open the bridge is five short blasts sounded in rapid succession. The signal shall be repeated until acknowledged in some manner by the requesting vessel. If the vessel does not continue its approach, this can be interpreted by the bridge tender as the vessel operator s acknowledgement and the bridge tender can cease his/her signal. C. VISUAL SIGNALS When the bridge can be opened immediately, the visual signal to acknowledge a request to open the bridge is one of the following: 1. A white flag raised or lowered vertically 2. A white, amber or green light raised or lowered vertically 3. A fixed or flashing white, amber or green light or lights D II BRIDGE TENDING MANUAL Page 11 EXHIBIT B

13 D. When the draw cannot be opened immediately, or is open and must be closed promptly, the visual signal to acknowledge a request to open the bridge is one of the following: 1. A red flag or red light swung back and forth horizontally in full sight of the vessel, or 2. A fixed or flashing red light or lights E. The signal shall be repeated until acknowledged in some manner by the requesting vessel. If the vessel does not continue its approach, this can be interpreted by the bridge tender as the vessel operator s acknowledgement and the bridge tender can cease his/her signal. V HURRICANES A. Federal regulations authorize drawbridges to remain closed during a natural disaster such as a hurricane unless the United States Coast Guard specifically directs otherwise. The regulations do not permit closure in anticipation of a disaster without prior U.S. Coast Guard approval. B. Authorities desiring to temporarily cease or restrict drawbridge openings to facilitate evacuation of land traffic before the arrival of a hurricane must obtain authorization from Commander, Seventh Coast Guard District. Call (305) , , or between 7:30 a.m. and 4:00 p.m., Monday through Friday. At all other times call the Coast Guard Command Center at (305) The duty officer will relay the request and furnish a response within minutes. Temporary closures are approved on a case by case basis and only if operation of the bridge impeded evacuation. Specific regulations may exist for certain bridges which require opening on signal during periods of storm warning or alerts. The bridge tender must not cease openings without specific approval from the District Structures Maintenance Engineer or his designated representative. C. High winds may make a drawbridge inoperable or subject to damage. Drawbridges are authorized to remain closed while experiencing sustained winds of 34 knots (39 mph) or more if the Department has determined that closure is required to prevent damage to the bridge. Closure of a bridge because of high winds shall be approved by the District Structures Maintenance Engineer or the Movable Bridge Administrator. D II BRIDGE TENDING MANUAL Page 12 EXHIBIT B

14 VI SPECIAL REGULATIONS A. In the absence of specific regulations, a drawbridge is required to open promptly on signal. Schedules for all drawbridges can be found in CFR 33, Part 117. The schedule for each bridge will also be provided to the bridge tender in the Operating Supplement of the Bridge Tending Manual. B. Except as provided by particular bridge opening schedules, drawbridges shall be opened promptly for the passage of vessels when a request to open has been given in accordance with the signaling procedures established. Under no circumstances is the bridge tender to question the vessel operator as to his/her right for a bridge opening based on the height of his/her vessel. If the tender advises the pilot that the vessel can pass under the bridge if the outriggers and/or antennas are lowered and the pilot states that the outriggers cannot be lowered, or the vessel operator is obstinate and/or refuses to comply, the tender is to open the bridge for the vessel and fill out a BRIDGE TENDER S REPORT ON UNNECESSARY BRIDGE OPENING gathering as much information about the vessel as possible and submit to the Bridge Tender Supervisor. C. The Department may obtain permission from the United States Coast Guard to temporarily alter the schedule or to temporarily close a bridge. When permission is obtained, the Bridge Tender Supervisor will inform the bridge tender and the bridge tender is required to comply with the temporary conditions. VII INSTRUCTIONS FOR BRIDGE MECHANISM OPERATION A bridge specific manual on bridge operations shall be issued by the District Structures Maintenance Engineer for each structure. As a minimum the manual should include: 1. Step by step instruction for routine operation of the bridge. This should include step by step shift change functions to review the bridge tender log, unresolved malfunctions, bypass seals and safety equipment. 2. Step by step instructions for operation of the bridge using auxiliary power. 3. Malfunction procedures which provide the bridge tender with step by step instructions for handling malfunctions likely to occur at the bridge. 4. A listing of all safety equipment to be maintained at the bridge. D II BRIDGE TENDING MANUAL Page 13 EXHIBIT B

15 VIII LIGHTING A. After sunset the bridge tender must be constantly alert to see that all lights are burning. If both span clearance lights are extinguished on one side of a bascule bridge, or in the case of Main Street Bridge, a single center span clearance light, is extinguished on either side of the bridge, this constitutes an on-call situation. The bridge tender on-duty when the lights have been determined to be extinguished will notify the on-call technician, write a new Drawbridge Malfunction Report, and log the status of the lights and the new DMR in the Bridge Tender Log. Once the DMR is written, it will be called in to the Jacksonville Bridge Offices at (904) B. Each bridge tender on duty during the hours of darkness shall check the lights at the beginning of his/her shift or as soon as it becomes dark. A record of the results of this inspection shall be entered in the BRIDGE TENDER LOG. C. Battery operated lights shall be kept in readiness at all times and must be placed in their proper place in the event of electrical power failures. IX. DRAWBRIDGE OPERATION DURING CIVIL DEFENSE EMERGENCIES During Civil Defense emergencies, normal drawbridge openings will continue unless directed by the Department at the request of the Area Civil Defense Coordinator or Emergency Operations Center. X. BRIDGE MAINTENANCE / INSPECTION A. The Department is responsible for the maintenance/inspection of the bridge structure and mechanical/electrical devices. The bridge tender is responsible for informing the Department of any malfunction of the controls or of any event that may have damaged any component of the bridge. B. When a maintenance/inspection crew arrives and departs, it shall be noted in the BRIDGE TENDER LOG. C. The bridge tender shall cooperate fully with the maintenance/inspection crew. The personal safety of himself/herself and all members of the maintenance/inspection crew is the utmost priority. Good, clear communication is vital while the crew is on duty. D. When maintenance/inspection is being performed on the bridge, the bridge tender shall communicate with the crew, prior to and during bridge openings. If the crew is in the machinery areas of the bridge, notification of an opening is absolutely necessary to D II BRIDGE TENDING MANUAL Page 14 EXHIBIT B

16 prevent injury to personnel. All Lock-Out, Tag-Out Procedures (Appendix C) shall be in effect for this contract. E. When an inspection/maintenance crew is to engage in activities on a movable structure in an area where operation of the machinery or electrical devices could be hazardous to the personnel, the supervisor of the crew shall personally tag the controls. If an opening is necessary during these inspection/maintenance operations of the bridge, the bridge tender must notify the supervisor and he/she must personally remove the tag from the controls before allowing the bridge tender to proceed with the operation of the bridge. The tag used for this procedure shall be requisitioned from the Lake City Sign Shop (Warehouse Item No ). F. The crew leader may give the bridge tender instructions that are contrary to the instructions given herein. The bridge tender is to comply with the crew leaders instructions and make a note in the bridge tender log to that effect. If the bridge tender cannot comply with the crew leader s instructions, he/she shall call the Bridge Tender Supervisor immediately for assistance. G. In all cases, the bridge tender must receive an acknowledgement from the work crew before proceeding with the opening. If the bridge tender has any doubts as to whether communication is fully understood, he/she should not proceed with any movement of the bridge span(s). D II BRIDGE TENDING MANUAL Page 15 EXHIBIT B
