This guidance is from the GSA PBS P100 criteria: Track Files
General. A track file uses a single aisle to give access to an otherwise solid group of open-shelf files. Access is gained by moving shelf units on rollers along a track until the proper unit is exposed. Special Requirements. Track files shall meet the following requirements: 1. The track file system shall be constructed entirely of steel. At least 1.4 mm (18-gauge) sheet metal shall be used for all parts of the shelving unit. 2. The system shall be no more than 2438 mm (8 feet) high, and a minimum clearance of 457 mm (18 inches) shall be maintained between the top of the shelving and the ceiling. 3. The sprinkler density shall be 12.2 (L/min)/m2 (0.3 gpm/sq. ft.) over 139 m2 (1500 sq.ft.). Sprinkler spacing shall be 9.3 m2 (100 sq.ft.) maximum. 4. The back cover of stationary end files shall be solid sheet metal. http://www.gsa.gov/gsa/cm_attachments/GSA_DOCUMENT/P100-2005_07_Fire_Life_Safety_R2-w-r-k_0Z5RDZ-i34K-pR.pdf Bill Brooks William N.
