~ <br />THERMO ft FLUIDS <br />T~. Responsibl. Solut;on <br />Sa m pling <br />There are many ways to samp le a tank. For Clor-D -Tect testing purposes, you should draw <br />a sample that is as representati ve as poss ible prior to pumping ! <br />When off-loading your truck into TFI tanks, a representative sample should be d rawn before <br />off-loading . This sample should be sufficient for tests of ch lorine components (us ing a Clo r - <br />D-Tect Q-4000 test k it), BS&W co ntent (using a centrifuge) and API grav ity. <br />Given the many unique characteristics of our trucks, trailers and tanks, you shou ld work <br />with your superv isor to develop t he most appropriate way to obtain a representative sample <br />of the fluid to be pumped. Th is may require unique sampling tools to penetrate stratified <br />layers to collect a composite sample . <br />Tes t ing (Ref e r also to the Ha loge n T esting Proced ures ) <br />If you are pumping for the first time at a specific location of a new customer, obtain <br />information about the fluid from yo ur customer. This information could include MSDS <br />and/or lab analyses . Also obtain, if available, any customer inventory lists of fluids used at <br />the facility . <br />Clor-D -Tect Q-4000 testing is to be performed at all times prior to pumping used oil from a <br />customer's tank i nto TFI truck tanks and prior to off-loading at a TF I faci l ity. There are no <br />exceptions! <br />If Q-4000 test results are below 800 ppm, the oil may be pumped. The exception is if you <br />are pumping from another used oil collector whose test results must not exceed 500 ppm. <br />If Q-4000 test results are between 800 and 1,000 ppm, the oil may be pumped only after <br />written approval from you r supervisor. <br />If Q-4000 test results are above 1,000 and below 4,000 ppm, t he oil is not to be pumped . <br />Contact your supervisor who will discuss with your customer the procedures to be followed <br />to meet the rebuttal presumption exemption . <br />If Q-4000 test results are 4,000 pp m or higher, the oil is never to be pumped! The oil is <br />hazardous and there are no exceptions. Contact your supervisor who will discuss disposal <br />options w ith your customer. <br />When off-load ing used oil into TFI ya rd tanks, test a representative sample of you r entire <br />truckload for chlorine components using a Q-4000 test (following the guidelines in 5.2 thru <br />5.6) and BS&W content using a centrifuge.
