2209.3.2.5.1.1 Barrier Wall Construction—Liquefied Hydrogen

Fire Code 2009 > 22 Motor Fuel-Dispensing Facilities and Repair Garages > 2209 Hydrogen Motor Fuel-Dispensing and Generation Facilities > 2209.3 Location on Property > 2209.3.2 Location of Dispensing Operations and Equipment > 2209.3.2.5 Liquefied Hydrogen Storage > 2209.3.2.5.1 Location on Property > 2209.3.2.5.1.1 Barrier Wall Construction—Liquefied Hydrogen
JUMP TO FULL CODE CHAPTER
The outdoor separation distance shall be permitted to be reduced to 5 feet (1524 mm) where a 2-hour fire barrier interrupts the line of sight between equipment, other than dispensers, and the exposure within the radial distance as indicated by the tabular value. The height of the barrier shall be a minimum of 6 feet (1829 mm) but no less than 1.5 times the height of equipment, other than the cryogenic storage vessel, measured vertically. The length of the wall shall be no less than 1.5 times the maximum diameter or length of the tank. The 2-hour fire barrier shall not have more than two sides at approximately 90-degree (1.57 rad) directions, or three sides with connecting angles of approximately 135 degrees (2.36 rad). When fire barrier walls on three sides are used, piping and control systems serving stationary tanks shall be located at the open side of the enclosure created by the barrier walls.
