U 3.7.3.4. Soap all service fittings and manways. Watch for active air bubbles, which indicate a leak. 0 3.7.3.5. Monitor the pressure for one hour. 3.7.4. AIR TEST OF SECONDARY TANK 3.7.4.1. Attach the quick -disconnect hose assembly from the end -tank monitor fitting to the primary -tank service fitting (with a female quick -disconnect fitting in place). This will allow air to transfer to the interstitial space. (See FIGURE 34 and FIGURE 3-13.) 3.7.4.2. Add air as required and stabilize the air pressure in the total tank system to 5 psig. 3.7.5. EXTERNAL SOAP TEST 3.7.5.1. Soap the entire exterior of the tank. Watch for active air bubbles, which indicate a leak. Pay special attention to fitting(s) and manways. Lift the tank to check the bottom. Do not roll the tank. 3.7.5.2. Monitor the pressure for one hour. AWARNING Do not stand under the tank. This could result in death, serious personal injury or property damage. 3.7.5.3. When the test is completed, carefully release the air pressure from the tank by opening the air -supply valve. 3.7.5.4. When the air flow stops, remove the test manifold. Do not connect air supply directly to the interstitial -space monitor fitting. Pressurizing the secondety tank (interstitial space) by itself may damage the primary tank or cause tank failure. 3.8.1. GENERAL 3.8.1.1. See FIGURE 3-10 and FIGURE 3-11. 3.8.2. PRIMARY BASE TANK (INTERNAL) 3.8.2.1. Keep the tank vertical (the reservoir on top) at all times or the liquid (brine) may drain from the reservoir. 3.8.2.2. Remove all temporary service fitting plugs, redope, and reinstall all fitting plugs except one for each compartment (needed for test manifolds) and the fitting on the reservoir. Install permanent plugs in all unused openings. Do not open the monitor fitting (if present) or monitoring fluid could be lost. 3.8.2.3. Check the liquid level in the reservoir. It should be ® about 1/4 full. 3.8.2.4. Visually check the interior of each compartment for liquid. There should not be any. 3.8.3. PRIMARY -TANK AIR TEST OF BASE TANK 3.8.3.1. Install the test manifold in the open service fitting. Connect the pressure source to the test manifold on the base tank. (See FIGURE 3-3 and FIGURE 3-11.) 3.8.3.2. Pressurize the primary tank to 5 psig. Allow the pressure to stabilize by adding or removing air as necessary. Note: The liquid level will rise during the air test. 3.8.3.3. Close the air -supply valve on the test manifold. Disconnect the air -supply line. 3.8.3.4. Soap all service fittings and manways. Watch for active air bubbles, which indicate a leak. Check the reservoir for bubbles in the monitoring fluid. (The level of the monitoring fluid will naturally rise due to the pressure in the primary tank.) 3.8.3.5. Monitor the pressure for one hour. Do not release air pressure. 3.8.4. PRIMARY -TANK AIR TEST OF END TANK(S) 3.8.4.1. Install the test manifold in the open service fitting in the end compartments. Connect the pressure source to the test manifolds. (See FIGURE 3-3 and FIGURE 3-12.) 3.8.4.2. Pressurize the primary tank of the end tank(s) to 5 psig. Allow the pressure to stabilize by adding or removing air as necessary. .-lmy.mamamm 3.8.4.3. Close the air -supply valve on the test manifolds. Disconnect the air -supply line. 3.8.4.4. Soap all service fittings and manways. Watch for active air bubbles, which indicate a leak. Check the reservoir for bubbles in the monitor fluid. (The level of the monitor fluid will naturally rise due to the pressure in the primary tank.) 3.8.4.5. Monitor the pressure for one hour. 3.8.4.6. When the test is complete, carefully release the air pressure from all compartments by opening the air -supply valve. 3.8.4.7. When the air flow stops, remove the test manifolds. 3.8.4.8. Check the liquid level in the reservoir. It should be at approximately the same level as the pretest level. • Do not connect air supply directly to the intersbtiatispace monitor fitting. Pressurizing the secondary tank (interstitial space) by itself may damage the primary tank or cause tank failure. 3.8.5.1. Check the exterior of the tank for monitoring fluid. (The monitoring fluid is dyed blue to distinguish between moisture and monitoring fluid.) If monitoring fluid is found, wipe the tank dry and verify that the monitoring fluid does not reappear. Lift the tank to check the bottom. Do not roll the tank.
