8 Appendix A: Letters of Approval July 6, 2001 Refer to: HSA-10/B87 Mr. James R. Keaton Vice President of Sales and Marketing Barrier Systems, Inc. 180 River Road Rio Vista, California Dear Mr. Keaton: In your June 22 letter, you requested the Federal Highway Administration s acceptance of your company s SafeGuard Gate System as meeting the requirements for a test level 3 (TL-3) longitudinal barrier under the National Cooperative Highway Research Program (NCHRP) Report 350. To support this request, you also sent me copies of Safe Technologies, Inc. June 22, 2001 report entitled NCHRP Report 350 Crash Test Results for SafeGuard Gate System, video tapes of the crash tests you conducted, and CD- ROMS containing test data for each of the crash tests. The SafeGuard Gate System (SGS) is a steel barrier specifically designed to span a permanent opening in a concrete median barrier ranging from 8 meters long to 16 meters long. The typical length of each gate section is 4 m and the effective overall height is 829 mm. The SGS is 700-mm wide at its base and 513-mm wide at the top. Each 4-m section weighs approximately 675 kg. Hinge assemblies at the ends of each unit and compressed air-activated, retractable wheels on each unit allow the SGS to be disconnected from the rigid barrier after removal of the aluminum cover plate and the 28.6-mm diameter ASTM C1018 steel connecting pin. The SGS can then be swung open from one end or completely removed to allow passage of vehicles. One or two persons can accomplish this process manually in five minutes or less. Enclosure 1 shows some of the design details for the SGS. Tests were conducted with an 820-kg vehicle at a 20-degree impact angle and with the 2000-kg pickup truck at 25 degrees. Both tests were run at the NCHRP Report 350 test level 3 (TL-3) speed of 100 km/h. Two critical impact point tests were also conducted with the pickup truck: one to test the hinge assembly in a 12-m span and one to test the SGS-to-concrete barrier transition in an 8-m span. One additional test was run with an 820-kg vehicle at the TL-2 speed of 70 km/h to confirm acceptable low-speed performance.

9 12-m long SGS was 570 mm. Summary reports for each of the four TL-3 tests are included in Enclosure 2. Based on staff review of the information you provided and its recommendations, I find the SafeGuard Gate System to be acceptable for use on the National Highway System (NHS) as an NCHRP Report 350 TL-3 device to close permanent openings from 8 to 16 meters in length in a rigid concrete barrier. Since the SGS is a proprietary device, its use on Federal-aid projects, except exempt, non-nhs projects, is subject to the conditions listed in Title 23, Code of Federal Regulations, Section Please do not hesitate to call Mr. Richard Powers at (202) if you have any questions regarding this acceptance letter.

18 Appendix B: Operating Instructions for Safeguard Gate System 16 m System Shown The Safeguard Gate System (SGGS) is designed to function as a crashworthy longitudinal barrier in accordance with the guidelines set forth in the National Cooperative Highway Research Program Report Number 350 and the AASHTO Roadside Design Guide and is simple and easy to operate. These brief instructions will demonstrate a method to open and close the system in a safe and efficient manner. General The SGGS system is normally in the closed position as shown in the above photograph. In this condition the system functions as a roadside barrier up to the levels required for the National Highway System (NHS). The system is designed to be able to be opened for incident management to allow emergency vehicle access or rerouting traffic to the other side of the highway. If the system is to be opened, proper traffic control practices (in accordance with local standards) should always be followed. General safety precautions relating to the operation of heavy equipment and the use hand tools and compressed air (when used) should also be followed. Ph or visit 30-Oct-07 / Page 18

Opening the System Once proper traffic control has been established at the site, two people can easily open the system in less than 5 minutes.

In either case, the hinge covers must be removed from both ends of the system.

This allows the cover to then be lifted out of the structure (Figure 3) so it can be placed in a convenient area for reinstallation, but out of the way during

19 Opening the System Once proper traffic control has been established at the site, two people can easily open the system in less than 5 minutes. The first step in this process is to decide whether the system is going to be completely removed from the opening or only swung open from one end (like a gate ). In either case, the hinge covers must be removed from both ends of the system. These hinge covers are held in place by four pins (two on each cover) at each hinge cover location, as shown in Figure 1. Figure 1 Figure 2 Hinge Cover pins Hinge Cover locking If additional security is needed at the site of a SGGS system, an agency lock can be applied to the cover opening handles so the covers cannot be removed. Once the hinge cover pins have been removed, the covers can be rotated outward as shown in Figure 2. This allows the cover to then be lifted out of the structure (Figure 3) so it can be placed in a convenient area for reinstallation, but out of the way during the following steps. Some find it convenient to place the covers inside of the gate structure through the opening in the top of the system. The covers weigh less than 40 pounds. Figure 3 Figure 4 Rotate Cover Outward Lift Cover from Hinge Area Ph or visit 30-Oct-07 / Page 19

20 Once all of the covers are removed (4 per system, two at each end), the main hinge pin is visible and can be removed as indicated in Figure 4. Remove one pin to open as a gate and both pins to completely remove the SGGS unit from the opening. Figure 5 Removing the Main Hinge Pin When the Main Hinge Pin is removed, the system needs to be raised onto the wheels so the SGGS can be moved out of position. The system can be raised with the manual jacks (standard) or with the pneumatic raise system (if that option is purchased). The manual jack system is shown in Figure 5. The handle is stored inside of the hinge area so it can be made secure if the system is locked (Figure 2). This method allows the system to be raised by turning the jack handle in the indicated position. The system should only be raised enough to clear any obstacles or debris around the system. Care should always be taken to ensure that you maintain positive control of the gate structure. If significant gradients are present, a tether should be attached to the moveable structure and to the anchored structure so the system can be slowly moved to the proper position.

21 Figure 5 Manual Jack System If the SGGS system is supplied with a pneumatic raise/lower system, an air supply can be used to assist with lifting of the gate structure. The air supply can be from an air compressor or from a static air supply bottle as shown in Figure 6. Figure 6 Air supply Bottle for Pneumatic Raise/Lower Option The operation of the pneumatic system is shown in Figure 7. A full set of instructions will be supplied with the system at delivery. It is important to follow the operating instructions for the pneumatic control system. This option is frequently used for conditions where the SGGS system is to be opened and closed many times in a short period of time. Ph or visit 30-Oct-07 / Page 21
