This docu
17、ment is a guideline for useby the truck driver and persons responsible for the load-ing and unloading of MC306/DOT406 cargo tanks. Itidentifies specific steps to ensure that product can beloaded into tank trucks and unloaded into both under-ground and aboveground storage tanks in a safe andefficient
18、 manner that protects the environment. It isintended to be used in conjunction with existing drivertraining programs and procedures.This document was prepared by a joint task forcemade up of representatives from the PetroleumMarketers Association of America, the NationalAssociation of Convenience St
19、ores, the Society ofIndependent Gasoline Marketers of America, AmericanPetroleum Institute, U.S. Department of Transportation,and the National Tank Truck Carriers, Incorporated.1.2 ReferencesAPI RP 1637Using the API Color-Symbol System toMark Equipment and Vehicles for ProductIdentification at Servi

21、aded when allequipment is used properly and when the person respon-sible for loading follows prescribed safety procedures.The driver (or loader) should be alert, equipment shouldbe properly maintained and safeguards against spillage,fire or product contamination should be rigidly observed. In order
22、to prevent product mixtures, the driver shouldbe familiar with the color-coding used to identify loadingand receiving equipment. For product color code, refer toAPI RP 1637, “Using the API Color-Symbol System toMark Equipment & Vehicles for Product Identification atService Stations and Distribution
23、Terminals“. Note: Some loading facilities may utilize a color-coding systemdifferent from API RP 1637. The driver should check with thefacility management to assure familiarity with the color-codingsystem used at each specific loading facility.CAUTION: For switch-loading procedures (i.e., loading di
24、stillatewhen the prior product carried in the tank or compartment was gas-oline or other flammable liquid), the driver (or loader) shouldcheck with the terminal personnel or dispatcher for instructions.Also refer to API RP 2003, Protection Against Ignitions ArisingOut of Static, Lightning, and Stray
25、 Currents. 2.2 Pre-loading ProceduresThe driver (loader) should determine the product tobe loaded into each tank truck and compartment. Notethe compartment number on the shipping paper for ref-erence when both loading and unloading. ShippingPapers must be handled in accordance with load rackprocedur
26、es and must be completed and carried on thetruck during transport to comply with U.S. Departmentof Transportation (DOT) regulations. Check the cargo tank and compartments as to prod-uct(s) previously delivered and if necessary followcleaning, flushing and drainage procedures in accor-dance with load
27、 rack procedures. In order to preventproduct mixtures or spills due to overfilling of tanktruck compartments and to ensure that correct quantitiesare loaded, all return gallons (retains) remaining in anyRP1007 Page 3 Monday, March 8, 2004 4:49 PM4API RECOMMENDEDPRACTICE1007compartments from the prev
28、ious delivery must beaccounted for. If necessary to drain product from acompartment, park the tank truck and drain only in anapproved area using an approved hose or bucket. Only ametal bucket that is properly bonded to the truck usingan approved bonding cable, should be used, never aplastic bucket.
29、Product should be disposed of in accor-dance with local operating procedures.1.Before pulling under the load rack, drivers shouldstop at the stop line or 50 feet (15 meters) in front of therack and inspect the loading area for product spills orany personnel or obstruction. Check adjacent loadinglane
30、s for problems. Turn off lights (daytime runninglights, if so equipped, should be handled according toload rack procedures), electrical equipment and elec-tronic devices, and all radios. 2.If the loading rack is not clear, set parking brakesand shut off engine. When the rack is clear, pull for-ward,
31、 spot truck for loading, set parking brakes, placetransmission in lowest gear and shut off engine. Do notuse cellular phones under the rack or in any other unau-thorized location.3.Walk around the tank truck and conduct a visualinspection for hot or deflated tires, defective brakes,damaged springs,
32、etc. Listen for air leaks in brake sys-tem, ensure product compartment identification dial (ifso equipped), is set, and proper DOT placards are inplace. This should be done either before or after pullingunder the rack.2.3 LoadingDrivers (loaders) should identify the location of theclosest loading ra
33、ck emergency shutdown control, por-table fire extinguishers and, where provided, the fireblanket and the load rack fire suppression system. Thedriver (loader) should also know the location of themechanical product flow shut-off valve and how tooperate it if the main flow-control valve malfunctions.T
34、ank trucks must not be left unattended at the load rack.Refer to terminal or company load rack procedures forPersonal Protective Equipment (PPE) requirementswhile loading tank trucks.RP1007 Page 4 Monday, March 8, 2004 4:49 PM5RECOMMENDEDPRACTICEFORLOADINGANDUNLOADINGOFMC 306/DOT 406 CARGOTANKMOTORV
35、EHICLES1.Make sure that all tank truck valves are closed.2.Connect the overfill protection plug/cord to the tanktruck. Wait for green (or permission) light to illuminatebefore proceeding.3.Check the vapor recovery hose for trapped liquid orother defects that would impede the free flow of vaporsto th
36、e rack system. Connect the vapor recovery hose tothe trailer. Completely close both camlock ears on thehose connector. A vapor-tight connection is required.4.Be sure the brake interlock system is working. 5.Connect the bottom loading arm(s). 6.Open internal valves for the compartment(s) beingloaded.
37、 7.Set the number of gallons (liters) to be loaded on themeter set stop.CAUTION: Under no circumstances should the overfill sensors beused as a meter stop. The pumps gradual slow down is controlledby the meter settings and use of the overfill sensors or other methodsof shutting down product flow can
38、 result in a sudden shock to theproduct pumps, resulting in possible damage to pumps and piping. 8.Confirm that products are being loaded into the cor-rect tank truck compartment(s), that the meter isproperly set for the compartment size and that no mix-ing of products occurs.9.When starting product
39、 flow, check all hoses and con-nections for leaks or drips. Stop loading immediately if leaks or drips occur. U.S.Environmental Protection Agency (EPA) regulationsrequire the tank truck to be vapor-tight while loading. Ifvapors are determined to be escaping during the loadingprocess, stop immediatel
40、y, notify terminal personneland your dispatcher/supervisor. 10.While vehicle is being loaded, driver (loader) mustremain near the set-stop or, where provided, hold thedead man switch. Maintain observation of the loadingat all times. Under no circumstances is the dead manswitch to be strapped down or
41、 by-passed.11.Precautions: Do not clean or make repairs to the vehicle whilein the loading position. Shut truck tractor doors to prevent dome lightfrom being activated. Only authorized personnel should be at theloading position.RP1007 Page 5 Monday, March 8, 2004 4:49 PM6API RECOMMENDEDPRACTICE1007
42、Do not use any electronic devices or cellularphones. Distractions such as eating or drinking areprohibited. Do not smoke except in designated areas.12.Never load tank truck vehicle compartments abovetheir safe fill capacity. 13.Monitor the meter closely during the loading pro-cess. Be prepared to pu
43、sh the stop button and the closestloading rack emergency shutdown control in case ofmeter overrun. Immediately report any meter overrun toterminal personnel.14.Overfill, Spill and Emergency Situations. In all situ-ations identified below, immediately notify terminalpersonnel and dispatcher/superviso
44、r. In an emergency, release dead man switch or pushrack emergency shutdown button or, if necessary,activate the load rack fire suppression system. In the event of a spill or compartment overfill, donot start or move the vehicle until the spill or over-fill is cleaned up. If a significant spill occur
45、s, leavethe area and alert other drivers. In the event of a fire, activate the load rack firesuppression system, leave the area and alert otherdrivers. If the previous shutdown steps do not stop the flow,the driver should activate the mechanical shut-offvalve, as described in Section 2.3, “Loading”.
46、 15.Once a tank truck compartment is filled, first closeall internal valves, then disconnect the loading arm andsecure the unloading coupler. Verify that proper productand quantities were loaded.16.Repeat process for each tank truck compartmentbeing filled. (Section 2.3, “Loading”, Steps 5- 15)17.Wh
