DELIVERY CREW ensures that the FIRE EXTINGUISHER(FEX) is properly positioned away from the T/T for accessibility (in case of emergency).

DELIVERY CREW coordinates the delivery with the CUSTOMER or authorized his representative. Requests for certification from the Manager or his representative when receiver is not in the list of authorized receiver.

CUSTOMER checks Delivery Note (DN) from DELIVERY CREW and verifies the following:

If the delivery address is correct.

If the identity of DELIVERY CREW and T/T tally (with whats indicated on the DN.

T/T dispatch time from Petron Bulk Plant (for first delivery) or the time it went out from previous customer (for succeeding deliveries).

NOTE: CUSTOMER, from time to time, checks if the calibration certificate of tank truck meter is updated (CC - 1 year validity only, renewed yearly by T/T).

CUSTOMER orients the DRIVER about the emergency response plan (EXIT POINTS, FIRE HYDRANTS, FIRE EXTINGUISHER, etc.) before unloading the product

For some accounts, T/T to comply safety checklist prior to unloading of product.

CUSTOMER checks VALVE BOX SEALS at: 1. Meter and valve compartment for the

first delivery point.

2. Liquid and vapor loading valves for the

succeeding delivery point if there is any.

NOTE: Seal number indicated in the delivery document should tally with the seal number installed in the T/T.

TYPES OF SEALS

1. Tank truck meter a. Meter head b. Temperature

compensator 2. Tank truck

compartments a. Meter box b. Loading valve

box

CUSTOMER checks T/T METER SEALS. 1. Meter head 2. Temperature compensator box provided with epoxy

NOTE: Checks for any sign of tampering.

CUSTOMER checks T/T METER SEALS. 1. Meter head (temperature compensator unit is already built-

in for digital T/T meters)

NOTE: Checks for any sign of tampering.

METER TEMPERATURE COMPENSATOR 1. Applied with

epoxy on the two bolts and nuts to seal off the compensator

TANK TRUCK CALIBRATION CERTIFICATE 1. Issued by ITDI 2. Valid for 1 year.

CUSTOMER takes OPENING READING of the RECEIVING TANKS one tank at the time if possible (to be witnessed by the DELIVERY CREW). The opening reading should be agreed by both parties

Opening: 15% = ______liters

Approximate conversion per 1%

1,000 gals = 37 liters



10,000gals = 487 liters

CUSTOMER writes down the reading in the DN (attested by the DELIVERY CREW). NOTE: READ FLOAT GAUGE CAREFULLY TO AVOID ERRONEOUS CALCULATIONS.

4/23/2014

CUSTOMER ensures that the RECEIVING TANK has enough ullage (empty space) to accommodate the delivery.

NOTE: ALL LPG TANKS MUST BE FILLED-UP TO 85% MAXIMUM LEVEL ONLY.

CUSTOMER witnesses the OPENING READING of the T/T METER TOTALIZER. NOTE: The reading should tally to what is indicated in the DN Opening : 12113241

DELIVERY CREW inserts DN in the T/T meter register.

4/23/2014

11

CUSTOMER (autogasul) closes the SERVICE VALVE of the RECEIVING TANK to prevent withdrawal of the product while the RECEIVING is on-going.

NOTE: THIS IS IMPORTANT IN RECONCILIATION OF FLOAT GAUGE READING VIS--VIS T/T REGISTER.

DELIVERY CREW connects the HOSE to the DISCHARGE VALVE of the TANK TRUCK.

NOTE: HOSE SHOULD BE PROPERLY LAID DOWN WITHOUT KINKS OR WARPS TO ALLOW NORMAL FLOW OF LPG.

WRONG

DELIVERY CREW shuts-off the PUMP & closes the DISCHARGE VALVE.

DELIVERY CREW closes the NOZZLE VALVE. Removes the HOSE and covers the FILLER VALVE. Returns the HOSE and FIRE EXTINGUISHER BACK to the TANK TRUCK compartment.

During unloading, CUSTOMER monitors the PRESSURE and FLOAT GAUGES of the RECEIVING TANK while the DELIVERY CREW monitors the pressure gauge and METER performance.

CUSTOMER signals the DELIVERY CREW upon reaching the 85% MAXIMUM level.

NOTE: -ALL LPG TANKS MUST BE FILLED-UP TO 85% MAXIMUM LEVEL ONLY. -RECEIVING TANK PRESSURE SHOULD NOT EXCEED 150 PSI.

POST DISCHARGING ACTIVITIES CUSTOMER takes the CLOSING READING of the RECEIVING TANK (witnessed by the DELIVERY CREW). Set the product to settle for about 15 20 mins before reading. Logs the READING on the DN. The tank closing reading should be agreed by both parties. DELIVERY CREW prints-out the METER REGISTER and pulls-out the DN (witnessed by the CUSTOMER). Logs the FINAL READING of the TOTALIZER (witnessed also by the CUSTOMER). CUSTOMER and DELIVERY CREW computes the quantity of product received based on the FLOAT GAUGE READINGS and the CALIBRATION TABLE (see SAMPLE).

4/23/2014

16

CUSTOMER and DELIVERY CREW compute for the TOTAL QUANTITY DELIVERED: 1) TOTALIZER: Check if quantity PRINTED with the TOTALIZERS NET READING (Closing Opening Readings). Signs net volume figures 2) FLOAT GAUGE: Check if the NET QUANTITY (Closing Opening Reading) matches the T/T TOTALIZER PRINT OUT. Signs net volume figures. Should there be an alteration in any figures, customer should put his initials on the erasures and alterations.

NOTE: IMMEDIATELY REPORT DISCREPANY beyond + 2% to 5% to Gasul Operations, Technical Services or Area Sales Executive FOR APPROPRIATE ACTION.
