6. STORAGE <br /> a. If possible, tanks are to be removed from the delivery truck and placed <br /> directly into the excavation. <br /> b. If the tanks are to be stored, rubber tires or approved bedding materials <br /> (see Section 3) must be used to protect the FRP secondary containment. <br /> C. Place the tires or approved bedding material within 36" of each end of the <br /> tank. <br /> 7. PRESSURE TESTING THE STEEL PRIMARY TANK <br /> a. Use two calibrated or new 0-10 psi pressure gages when pressurizing the <br /> primary steel tank. <br /> b. The maximum test pressure for the primary tank is 5 psig. <br /> C. Gages should be checked for operation and accuracy before use. <br /> Accidental use of vacuum gages on pressure tests has caused serious <br /> accidents. <br /> d. WARNING: Air testing with over 5 psig is hazardous and may damage the <br /> tank. Do not air test a tank which has previously contained flammable or <br /> combustible liquids. <br /> 8. VACUUM TESTING THE FRP SECONDARY CONTAINMENT <br /> a. CAUTION: Do not pressurize the FRP secondary containment. <br /> b. SUPERTANKS are shipped with a removable vacuum gage and a minimum <br /> of 10" mercury vacuum in the annular space. For the purpose of FRP <br /> secondary containment damage detection during installation and backfill, <br /> it is recommended that the annular space remain under vacuum for as long <br /> as possible. <br /> C. Do not perform any type of annular space testing without first consulting <br /> with a Trusco Tank representative. <br /> Installation Instructions 5- Rev. 8/19/94 <br /> Trusco Tank Inc. . P.O.
