**Site:** Office of River Protection Hanford

**Facility:** Tank Farms, 291-AR Filter Building

**System:** Fire Protection System

**System Classification:** General Service System

**System Safety Function:** Provide Fire Protection for the 291-AR
Filter Building

**[OBJECTIVE:]{.underline}**

**VSS-1** **This vital safety system is operational and personnel and
processes are in place that ensures its continued operational
readiness.**

**VSS-1.1** VSS safety functions are defined and understood by
responsible line managers, and supporting information/documentation is
available and adequate. System testing is adequate to ensure
operability. (Review Approach items 1, 2, 3 and 7)

**VSS-1.2** The backlog for surveillances, tests, inspections,
maintenance, repair, upgrades, or other work on the system is managed
and kept to an appropriate minimum. (Review Approach item 6)

**VSS-1.3** Configuration Management and Maintenance programs
effectively ensure operational availability of the system. (Review

**[CONCLUSIONS:]{.underline}**

All facilities are analyzed for compliance with NFPA 80A, \"Recommended
Practice for Protection of Buildings from Exterior Fire Exposures.\"
This analysis helps assure that fire from the outside of the building
will not affect the facility. The standard ground cover around/above the
291-AR filter building is gravel and pavement that provides a firebreak.
Operations crews routinely clean up transient combustibles. This
facilities replacement cost is valued at over \$1M and should have a
fire suppression or detection system installed. The facility and its
equipment are not operational and installing a fire suppression system
for this non-occupied building is currently not planned.

A new Tank Farm Contractor fire hazards analysis (FHA) has been
initiated. The FHA is scheduled for completion in FY 2001 and is funded.
The process will include a review of all facilities especially in
regards to facilities that are being decontaminated and decommissioned.
The process includes as a final step, issuing exemptions for those
facilities that will not meet code requirements as specified in the
Standards/Requirements Identification Document (HNF-SD-MP-SRID-001,
Section 12.8). An update to the Fire Hazards Analysis has been initiated
to re-evaluate the fire hazards and determine adequate required
protection.
