11 <br />2.1.3.5. Do not roll the tank to move it. <br />2.1.3.6. When handling a tank with a bottom sump or fitting, always <br />take extra care so that the bottom sump or fitting is not damaged by <br />contact with any other object, such as the truck bed or the ground. <br />2.1.4. Whenever a tank is temporarily placed aboveground at <br />the site, chock it in place to prevent rolling. (See FIGURE 2-3.) <br />Tie the tank down if high winds are expected. <br />FIGURE 2-3 <br />3.1. GENERAL <br />3.1.1. Xerxes tanks are tested prior to shipment, but the tank <br />must be retested at the site prior to installation — even if shipped <br />with the optional vacuum in the interstitial space or wet <br />interstitial space — in order to verify the absence of shipping and <br />handling damage. <br />3.1.2. The tester is responsible for verifying that all of the test <br />equipment is in good working condition, and is properly <br />configured and calibrated. <br />3.1.3. Construct a test manifold with two air -supply gauges as <br />shown in FIGURE 3-1. Each air -supply gauge must have a <br />maximum full-scale reading of 15 psig with 1/4 -Ib. or 1/10 -Ib. <br />increments, and a pressure -relief device set at 6 psig [4 psig for <br />12 -foot -diameter tanks]. <br />Air -Supply <br />Air•Supply Valve <br />Gauge Air -Supply <br />Gauge <br />r Pressure -Relief <br />Dev ce <br />FIGURE 3-1 <br />3.1.4. In air tests, temperature change could be a factor in <br />changes in gauge readings. <br />Note: Multiple test manifolds are required to test <br />multicompartment tanks. <br />3.1.5. It is the installer's responsibility to select a thread sealant <br />that is compatible with the product being stored. Some sealants <br />cannot be used with some products. Remove, clean and redope <br />all factory -furnished temporary plugs with appropriate thread <br />sealant. Install permanent plugs in all openings where piping will <br />not be installed. Make sure all manway bolts are tightened, and <br />fitting plugs are properly doped and sealed. <br />Ll <br />3.1.6. When checking the tank for leaks during an air/soap test, <br />rotate the tank to check the bottom, unless it is a tank filled with <br />monitoring fluid. <br />Ia icy deli <br />Never rotate a tank filled with monitoring fluid. See <br />SECTION 3.4. and SECTION 34 for instructions regarding <br />these tanks. <br />3.1.7. Before rotating the tank during an air/soap test, place <br />protective material on the area on which the tank will be rotated. <br />Make sure the area is flat and is free of large or sharp objects, <br />such as rocks, which may damage the tank. <br />3.1.8. Rotate the tank slowly and carefully to avoid developing <br />too much momentum. Momentum can grow because fittings on <br />top of the tank make it top heavy. Make sure the tank's fittings <br />and manways never touch the ground. Do not rotate the tank <br />more than 1200 from the initial starting point. <br />WARNING <br />Always secure the tank before moving or lifting it This is <br />commonly done by connecting a crane or backhoe to the <br />lifting lugs. Failure to do so could result in death or serious <br />injury. <br />WARNING <br />While moving or lifting the tank, do not position any part of <br />your body underneath the tank. This could result in death <br />or serious injury. <br />WARNING <br />Do not lift or hoist a tank under pressure. This could result <br />in death or serious injury. <br />3.1.9. Refer to the appropriate section below for instructions for <br />the following situations: <br />3.1.9.1. For testing a single-wall tank, see SECTION 3.2. <br />3.1.9.2. For testing a double-wall tank with a dry interstitial <br />space, see SECTION 3.3. <br />3.1.9.3. For testing a double-wall tank with a wet interstitial <br />space, see SECTION 3.4. <br />3.1.9.4. For testing a single-wall multicompartment tank with a <br />single-wall bulkhead, see SECTION 3.5. <br />3.1.9.5. For testing a single-wall multicompartment tank with <br />double-wall bulkhead(s), see SECTION 3.6. <br />3.1.9.6. For testing a double-wall multicompartment tank with a <br />dry interstitial space, see SECTION 3.7. <br />3.1.9.7. For testing a double-wall multicompartment tank with a <br />wet interstitial space, see SECTION 3.8. <br />3.1.10. If damage is detected, do not attempt repairs. Contact <br />the UST coordinator at the Xerxes plant nearest you. Telephone <br />and fax numbers are found on the back cover of this manual. <br />
