Sprinkler System Impairment Procedure

TABLE 3

FINAL SYSTEM TEST WORKSHEET

TEMPORARY IMPAIRMENT OF SPRINKLER SYSTEM

The Contractor is to designate an Impairment Coordinator who will be responsible for coordination of system impairment. The Impairment Coordinator shall become thoroughly familiar with all on-site organizations and contact personnel and will impair systems as defined below.

Taking fire protection systems out of service (impairment) for maintenance, testing, and repair shall be coordinated with installation fire department personnel. The Impairment Coordinator is to alert the COR when and which systems will be taken out of service and for how long on a daily basis. It will be the responsibility of the Impairment Coordinator to deactivate the fire alarm system for sprinkler systems being taken out of operation. The Impairment Coordinator will also notify Installation Fire Department and Dispatch of the specific systems that are being impaired. Training will be provided at the beginning of the project to familiarize the Impairment Coordinator with this procedure. No more than two systems may be taken down in a single building at a time. Systems are to be adjacent to each other. No more than 4 systems may be taken down throughout the site at one time. No sprinkler systems may be left impaired overnight unless a 24-hour fire watch is posted to guard areas that are covered by the impaired sprinkler system. Fire watch is the responsibility of the Contractor.

The contractor shall provide NICET Level 3, NICET Level 4, or FPE personnel at the main fire alarm supervising panel in building 911 during all tests that require reporting to the main fire alarm supervising panel. Personnel in Building 911 shall be responsible for clearing all fire alarm testing related signals at the main fire alarm supervising system.

There are several buildings that will require special attention to the impairment procedure. These buildings are high traffic buildings including Buildings 54, 81, 404, 405, 255, 2012, and the administrative area of 2001; and laboratories located in certain areas of Building 85.

PROCEDURE FOR SYSTEM IMPAIRMENT

The Impairment Coordinator shall notify the COR 48 hours prior to the impairment of a sprinkler system. This shall be done for EVERY system that is impaired during the project. Installation Fire Inspectors need to conduct a Fire Safety check of building or area that will be affected by the system impairment prior to deactivation of the sprinkler system. Additionally, any Hot Work required to be completed in the affected area must be done prior to impairment of the system. No Hot Work permits will be granted during system impairment. The following actions will be taken by the Contractor as required by NFPA 25, Chapter 15.

The Impairment Coordinator shall perform the following functions in conjunction with the COR. The Impairment Coordinator shall:

Alert the area manager(s) that will be affected by the impairment of the sprinkler system.

Alert Installation Fire Department personnel of the specific sprinkler systems that are about to be impaired.

Alert Central Dispatch of the impending specific sprinkler systems impairment.

The Impairment Coordinator will complete the Impairment Worksheet for each system. A copy of this worksheet is provided at the end of this exhibit as Table 1. A copy of the Impairment Worksheet is to be saved in the system file after the sprinkler system has been reactivated.

The Impairment Coordinator will complete the Fire & Life Safety System Permit/Impairment Tag, see Figure 1 attached.

The Impairment Coordinator shall authorize the preplanned impairment and verify that the following procedures have been implemented:

The extent and expected duration of the impairment have been determined.

Implementation of mitigating measures for the areas or buildings involved have been considered during the period that the system is impaired. This considers the building occupancy type, nature and duration of impairment, building occupancy level during the impairment period, active work being conducted on the fire alarm and fire sprinkler systems during the impairment, condition of other fire protection systems and features, and hazards and assets at risk.

When an automatic sprinkler system is placed out of service, the Impairment Coordinator will arrange for a fire watch for all portions of the building left unprotected by the shutdown until the fire alarm and sprinkler systems have been returned to service.

Contractor shall provide a fire watch for areas unprotected by impaired fire suppression systems or impaired fire alarm systems when an impairment lasts more than 10 hours in a 24 hour period. Fire watch must comply with NFPA 25, 15.5.2.4 and A.15.5.2.4.b. A fire watch will be composed of individuals beyond normal staffing, assigned to walk the areas affected. The number of fire watch personnel utilized will be determined by the Impairment Coordinator. During a fire watch, personnel conducting this activity will log information on the Fire Watch Log Sheet. The log sheet is to be updated HOURLY during a system impairment. A copy of this log sheet is provided as Table 2 at the end of this exhibit.

Fire watch personnel used for system impairments must be specially trained in fire prevention, the use of fire extinguishers, and in occupant and fire department notification techniques.

When work on a fire sprinkler system is complete, a full flow test shall be completed prior to the release of this system back into service. The Impairment Coordinator shall coordinate the following activities:

The Impairment Coordinator is to assure that the fire sprinkler system is ready for a full flow test.

The Impairment Coordinator must provide notice to the DLA fire department inspector at least 24 hours prior to the time that testing is required.

At the agreed upon time for the test, the full flow test is to be conducted by the Contractor and personally witnessed by the Installation Fire Inspector and the COR.

The test procedure to be utilized will depend on the type of sprinkler system being tested. Procedures for dry-pipe and wet-pipe sprinkler systems are as follows:

Wet-Pipe Sprinkler Systems The Fire Protection Specialist shall conduct the Final System Test and shall provide a complete demonstration of the operation of the system. This shall include operation of control valves and operation of inspector's test valve to verify operation of associated waterflow alarm switches. After operation of control valves has been completed, the main drain test shall be repeated to assure that control valves are in the open position. In addition, the representative shall have available copies of as-built drawings and certificates of tests previously conducted. The work shall not be considered accepted until identified discrepancies have been corrected and test documentation is properly completed and received. All test data shall be recorded on the Final System Test Worksheet. A copy of this worksheet is provided as Table 3 at the end of this exhibit.

Dry-Pipe Sprinkler Systems The Fire Protection Specialist shall conduct the Final System Test and shall provide a complete demonstration of the operation of the system. If applicable, the nitrogen generator system by-pass shall be tested to verify that system pressure is restored in the time specified by NFPA. Before trip testing a Nitrogen-Supervised system, the isolation valves for the nitrogen generation system shall be shut. After testing a Nitrogen-Supervised system, the Nitrogen Power Saver Manifold Sampling Lines shall be disconnected and cleared of possible debris. The Nitrogen bypass shall be shut and the Nitrogen Generation system be put back into normal service after system pressure reaches normal, supervisory status. Testing shall also include operation of control valves and operation of inspector's test valve to verify operation of associated waterflow alarm switches. After operation of control valves has been completed, the main drain test shall be repeated to assure that control valves are in the open position.

Each dry pipe valve shall be trip-tested by reducing normal system air pressure flowing water through operation of the inspector's test connection. Test results will be witnessed and recorded. Test results shall include the number of seconds elapsed between the time the test valve is opened and tripping of the dry alarm valve; trip-point air pressure of the dry pipe valve; water pressure prior to valve tripping; and number of seconds elapsed between time the inspector's test valve is opened and water reaches the orifice. In addition, the Fire Protection Specialist shall have available copies of as-built drawings and certificates of tests previously conducted. The work shall not be considered accepted until identified discrepancies have been corrected and test documentation is properly completed and received. After the system has been tested and drained, the system shall be drained periodically for at least 2 weeks until it can be assured that water from the system has been removed. The Contractor shall submit the Final System Test Worksheet. A copy of this worksheet is provided as Table 3 at the end of this exhibit.

A successful test shall meet the requirements of the applicable sections of NFPA 25. This will include at a minimum:

Proper operation of the clapper valve within the valve house upon manual operation of the ITV (Inspectors test Valve).

Proper operation of the water motor gong.

Proper operation of fire alarms both locally and at Central Dispatch. This includes confirmation of tamper switch operation, flow switch and pressure (as applicable) operation. This shall be confirmed through Dispatch via the Fire Inspector or the COR.

Upon successful testing of the sprinkler system, the Installation Fire Inspector shall sign-off on the Impairment Worksheet. In the event that the sprinkler system does not pass the sprinkler test, the reasons for system failure shall be documented and forwarded to the COR for disposition. In either case, the sprinkler system is to be reset and prepared for operation.

Alert the area manager(s) that the impaired sprinkler system has been returned to service.

Alert on-site Fire Department personnel that the sprinkler systems have been placed back in service.

Alert Central Dispatch that the sprinkler systems have been placed back in service.

The Impairment Coordinator will remove the Fire & Life Safety System Permit/Impairment Tag (Figure 1). That tag will be submitted with the Impairment Worksheet.

The Impairment Coordinator will finalize the Impairment Worksheet for that particular system. A final copy of the Impairment Worksheet, the Firewatch Log Sheet, the Impairment Tag, and the Final System Test Worksheet are to be submitted to the COR at the conclusion of the system repair and final system test.
