7.0 STATEMENT OF WORK REQUIRED

7.1 Remove and replace all interferences, rig and unrig, stage and unstage, make all disassemblies and subsequent reassemblies, provide and operate equipment, and supply all services and assistance to accomplish the thorough examination, testing and repair of Fire & Smoke dampers in accordance with SOLAS & USCG requirements. Use references 2.1.1 and Enclosures 2.2.1 and 2 for guidance.

7.2 Open up all overhead access doors/panels, remove all overhead panels (in staterooms, passageways and compartments) remove joiner panels, CBG panels within the mission bay, bolted access plates and any other interferences to access to all fire dampers, fire damper reach rods and reach rod universals.

7.3 Inspect, test and service each Fire & Smoke damper shown in Ref 2.1.1 and listed in Encl 2.2.1. Note any deficiencies and submit a report of all as found conditions to the MSCREP including all recommended repairs and/or replacement parts. Ensure:

1) full unobstructed access to dampers is provided.

2) where placed behind ceilings or linings, they are provided with an inspection door marked to identify the damper. Similar identification is required on any remote controls.

3) each is marked with red letters at least ½ inch (12.7 millimeters) in height stating “VENTILATION FIRE DAMPER”

4) each is fitted with an indicator showing whether the damper is OPEN or CLOSED.

5) each damper is cycled through its closure & opening. Remove access covers to visually examine the damper blades. When shut, the fire dampers shall have close contact with a steel strip throughout their circumference.

6) there is no interference with damper operation by rusted, bent, or misaligned parts, damaged blades, or defective hinges.

7) the damper frame is not penetrated by foreign objects to prevent proper operation.

8) the fire integrity of the divisions are maintained at openings and penetrations.

9) the fusible link, if fitted, is temporarily removed and damper closes completely and latches closed (where latch provided).

10) the fusible link is not damaged or painted. If damaged, it shall be replaced.

11) all exposed moving parts are dry lubricated per manufacturer’s instructions.

12) after any repairs, the damper shall be retested for proper operation

7.4 Fire dampers which are operated automatically shall be in the closed position within 2 minutes after the commencement of the test. (2010 FTP CODE) ANNEX 1 - FIRE TEST PROCEDURES; 2.2.5 7.5 Fire dampers which are operated with a manual system shall be closed at the test time of 1 minute. (2010 FTP CODE) ANNEX 1 - FIRE TEST PROCEDURES; 2.2.6 7.6 Automatic fire dampers protect “A” Class divisions, galley range hoods, laundries and drying rooms, cargo spaces, machinery spaces and vehicles spaces. In addition to the tests outlined in 7.3 each automatic fire damper is:

1) to be operated both automatically and manually from both sides of the division.

2) to demonstrate the failsafe mechanism closing the damper in a fire upon loss of electrical power or hydraulic or pneumatic pressure loss.

3) to demonstrate remote-control arrangements for shutting off the galley range hood and laundry and drying room exhaust fans and supply fans from within the space and for operating the fire damper 7.7 The contractor shall complete Enclosure 2.2.2 for each Fire & Smoke Damper listed in Encl 2.2.1 and submit a report with the data to the MSCREP:

7.8 Testing is to be coordinated with the MSCREP, ABS and USCG Surveyors to allow for random observation if deemed necessary.

7.9

Upon completion of all inspections, tests & repairs leave the Dampers in a ready for service condition. Conduct a final inspection with the MSCREP.

7.10 Manufacturer’s Representative: None

7.11 Preparation of Drawings:
