Prepared by David Rabb Approved by Randy Golding Tracer Research Qq : TracerT�zp G iideae Dare 01115104 Field Guideline v_9 Lm,00rtant Notes: 1. Do not use helium onsite before a pretest Using helium before PSI arrival reduces our abilities to locate leaks. 2. Do not put fuel in any part of the system. Placing fuel in the tanks before the test is completed will add additional time to the test protocol which will increase cost . . 3. Flex connectors that will not tolerate M vacuum (29"of mercury) will increase cost of the test, by requiring the test period to be extended We recommend using flex connectors that can tolerate a full vacuum. Metal core, fire rated and possibly some non-metal flex connectors are rated for full vacuum. If non-metal SIS braided connectors are installed follow the guideline and install ball valves as needed (See attachment for differences.) 4. We must know what components you are using on your site in order to have 'the proper testing equipment. Please give us this information ASAP. 5. Scheduling is important to you our dent. The more advance notice we receive, the better our ability will be to service you on time. Please give Praxair a tentative start date the day you begin construction. As schedule adjustments occur, please keep us informed. A* eek before you set the tanks, please contact Praxair and give us a firm date for your ELD TracerTight Pre -Test. 6: 'There should be a construction crew onsite with all equipment, tools, and any supplies necessary to complete any repair.

If water ballast is used, do not fill tanks completely. Leave a 12" or greater air space in the top. This will allow us to evaluate the top of the tank only. 7) Have all piping in trenches supported by backfill so no stress is everted on the piping. (Do not cover the sides of the piping.) 3) Every secondary bootlfttting must have a test sampling port or bypass system installed. 9) It is mandatory to have a secondary test port boot at the -far ends of each secondary section. 10) Third containment conduit must have test ports at each end of each containment section. 11)AlI product/Vapor return shear valves to be capped and primaries under 10 to 50 psi pressure and holding. 12) Vent piping, vent r serfs should be completed to finish height, must be capped, and under 10 to 50 psi pressure and holding. 13)All piping secondary lines shall have 5psi pressure. 14)For piping that includes Teflon flex connectors do the following: a, Inst ill %" test ports with bail valves and r/4" barb fittings in all primary vent riser c, Install 'W' gall valves with I/�" barb fittings in the test ports of all primar'j product & return sheer v:,lve test, sorts TF! %' !PIFOR:bGiTTU!`/!S '!tG['rR "%iF P LUvelR SER%Tc INC .liVD 7YL1(NGT38T^v11`ISL D.
