Scope of Work for Replacing Antifreeze in Fire Suppression Systems at The Truro Coast Guard Station (NEED Building) within the Cape Cod National Seashore, National Park Service.

Project Overview

This project involves the replacement and recycling of antifreeze from the fire suppression system at the historic structure located within the Cape Cod National Seashore at the Historic Truro Coast Guard Station (NEED Building). Due to the historic nature of heating systems in this structure, antifreeze is essential for preventing freeze damage during colder months. This scope outlines the necessary steps to safely and effectively complete this project.

1. Preparation

Site Assessment:

Conduct inspections of the fire suppression systems at the Truro NEED Building to confirm system integrity and functionality.

Safety Plan Development:

Develop a safety plan that includes procedures for handling antifreeze and flushing agents, addressing potential hazards, and ensuring worker safety.

Notification:

Notify all relevant stakeholders, including park management and staff, about the project schedule and any potential disruptions to normal operations.

2. Antifreeze Removal

Truro Coast Guard Station (NEED Building):

Safely drain the existing 30 gallons of antifreeze from the fire suppression system unit providing protection to the attic.

Use appropriate containment measures for safe removal and disposal.

Transport the drained antifreeze to an approved recycling facility.

3. Flushing Fire Suppression Systems

System Flushing:

Flush the Truro NEED Building suppression systems with a specialized cleaner to remove any residual antifreeze and contaminants.

Follow manufacturer guidelines for the cleaning agent used, ensuring that the flushing process protects the integrity of the systems.

Collect and properly dispose of the flushing agent as per environmental regulations.

4. Antifreeze Replacement

Antifreeze Selection:

Procure the appropriate type and quantity of new antifreeze that meets fire suppression system specifications and environmental regulations.

NFPA 13

8.6.2.1. Antifreeze solutions shall be listed for use in sprinkler systems.

A.8.6.2.1. Where existing antifreeze systems have been analyzed and approved to remain in service, antifreeze solutions should be limited to premixed antifreeze solutions of glycerine (chemically pure or United States Pharmacopoeia 96.5 percent) at a maximum concentration of 48 percent by volume, or propylene glycol at a maximum concentration of 38 percent by volume. The use of antifreeze solutions in all new sprinkler systems should be restricted to listed antifreeze solutions only. Where existing antifreeze systems are in service, the solution concentration should be limited to those noted in A.8.6.2, and the system requires an analysis and approval of the authority having jurisdiction to remain in service. Antifreeze that is “UL certified” meets the definition of listed in accordance with this standard.

Installation:

Refill the fire suppression systems at both sites with new antifreeze:

Truro NEED Building: Replace 30 gallons.

Ensure proper connection to the system and verify that the antifreeze is distributed evenly.

5. System Testing and Verification

System Testing:

Conduct pressure tests and functional tests on the fire suppression system to verify successful installation and operation after replacement.

Inspect for any leaks or issues that may require adjustments or repairs.

Documentation:

Document the procedures, materials used, and testing results for compliance and historical records.

6. Cleanup and Final Inspection

Site Cleanup:

Thoroughly clean the work area, removing any debris, tools, or materials used during the project.

Final Inspection:

Conduct a final inspection of the system and areas to ensure everything meets safety standards and is restored to its original condition.

Conclusion

This project will ensure that the fire suppression systems at the Historic Truro Coast Guard Station are properly maintained, enhancing fire safety for this important historical structure. Implementing the outlined scope of work efficiently and safely is essential to the continued preservation of this site.
