2. If the motor is running but fuel does not flow from the nozzle. There are several reasons as follows. - The fuel level in the tank is lower than the end of the suction pipe. - The air ventilation pipe of the tank is clogged. - Clogging of the filter or check valve. - Bypass valve in the pump is incorrect. - Particles could be stuck at the valve seat, preventing it from closing. - Excessive wear on the valve seat and bypass valves. - Broken or loose driving belt. - The floating valve in the air chamber is stuck in the open position, causing air to circulate within the chamber. To solve this, open the cover of the air chamber, check the floating valve core and valve whether they are fully closed. - When running the system for the first time, there may not be any fuel flow during the first 2-3 minutes. Please wait for a moment because the delay could be caused by fuel that flows back to the tank from the pump and suction pipe (regular pumps do not need lubrication). - There is a leak in the suction pipe. Check by closing the hole from the ventilation chamber with your finger. If there is a lot of strong wind coming out, then there are many leaks in the pipe. - Clogging of the suction pipe can be measured by using a vacuum gauge to measure at the cover beside the filter grille, while running at full power with handle nozzle fully open. If the readings are from 13-15 inHg, then the suction pipe is clogged. The normal reading should be 7-8 inHg. - The suction pipe is too close to the bottom of the tank – it should be 3 inches above the tank floor. - Nozzle is malfunctioned. 3. The pump is working but can only dispense small amount of fuel - Low fuel level in the tank. - Part of the ventilation duct is clogged. - Filter is dirty and should be removed and washed. - Bypass valve is not properly closed. - Loose driving belt. - Low voltage. - Motor malfunction or several electrical equipment sharing the same power cord. - Leakage in the suction pipe. - Part of the suction pipe is clogged – check by using a vacuum gauge (1.9). - Check if the valve is stuck. - Nozzle is malfunctioned. 99

SERVICE STATION STANDARD 4. Possible causes of motor malfunction - The breaker switch in the ECB housing malfunctions. - Motor switch malfunction. - Electrical problem causes motor to malfunction. 5. Possible causes of inconsistent fuel flow - Check valve malfunction, - The air duct in the air chamber is clogged, - Meter malfunction. 6. Product leaks through ventilation pipe while the pump is working. Possible causes may include; - The oating valve in the air chamber is in locked position, causing fuel overflow, - The return copper pipe at the fuel chamber is bended or pressed into narrow   shape, hence obstructing the flow, - The UGT is higher than the dispenser , - Jumping of the digital display may be caused by the incomplete closing of the   check valve, or relief valve remains open, - The gasket in the piping is leaking or the hose is leaking. 100

SERVICE STATION STANDARD 5.2.4.1.16 Knowledge of the meter examination and basic volume measurement 1. The fuel meter with 2-year valid certification Reference source: The Weights and Measures Act B.E. 2542 (1999) “Section 25 In selling, purchasing or exchanging commodities with others, providing Weighing and Measuring Services, or using Weighing and Measuring Instruments for the purpose of calculating remuneration, taxes and revenues, and fees, no person shall use any Weighing and Measuring Instrument without the verification under Section 30 or with the verification expired under Section 33, whether or not it is a weighing and measuring instrument exempted by the Ministerial Notifications under the second paragraph of Section 29 ..........”. “Section 33 The term of verification for each type of Weighing and Measuring Instru ments shall be prescribed in the Ministerial Regulations. In issuing a verification on the instrument and in the verification certificate. “The Ministerial Notifications prescribe the term of verification of the Weights and Measures Act B.E. 2542 (1999), type, characteristics, details of materials used for production, contingency rates and verification of Weighing and Measuring and guidelines and methods for registration of individual marks B.E. 2542 (1999) “Article 89 requires that the fuel meter at the service station (and the fuel meter used for transportation) has a 2-year certification. Sellers/service stations must comply with the following: (1) Notice that the important letter for the verification or certification plate has an expiry date beginning on January 26, 2006. From this date the fuel meter cannot be used to buy/sell fuel again. The service station (or the oil depot) must apply for inspection and cer tification of fuel volume gauge in order to use it for additional buying/selling of fuel products. Picture 5.85: A 2-year Certificate Plate   (2) Informing the service station (or the oil depot) that using the fuel volume meter which has an expired certification, shall be liable to punishment under Section 70 (impris onment not exceeding 6 months or a fine not exceeding 20, 000 baht, or both) (3) For the fuel meter that received certification before this ministerial regulation is enforced, (verified before 27 January 2004) can continue in use until the meter is not accurate and must be recertified again. 106

2. Usage of fuel measuring meter for the purchase/selling of fuel products. At present, fuel products are expensive and affect the consuming public. Ministerial Regulations B.E. 2549 (2006) stipulates methods of inspection and certification that have a high degree of sophistication, requiring a calibration bucket or measuring tank with a volume of 5 liters and 20 liters, taking into consideration the accuracy of the fuel flow meter while in use as following: (1) A test at a volume of 5 liters shows permissible tolerances of ±25 ml. during verification process and ±50 ml. during actual dispensing test, (2) Atest at a volume of 20 liters shows permissible tolerances of ±100 ml. during verification process and ±200 ml. during actual dispensing test, (3) A test at a volume of 1.0-1.5 liters shows permissible tolerances of ±20 ml. during verification process and ±40 ml. during actual dispensing test, (4) The variation range of dispensing 5 liters of fuel is ±50 ml. (the difference between dis pensing 5 liters of fuel with the maximum and minimum inaccuracies) and the range dispensing 20 liters has tolerances of ±200 ml. (the difference between dispensing 200 liters of fuel with the maximum and minimum inaccuracies) (5) Tolerance for every flow rate that has discrepancy on the same outcome tendency (gaining side or losing side); a) A test at a volume of 5 liters at an approximate flow rate of 4-6 liters/minute (L/m) has tolerances of ±25 ml. A test of 10 liters at an approximate flow rate of 8-12 L/m has ±50 ml. tolerances. A test of 20 liters flowing at approximately 18-22 L/m has ±100 ml. tolerances, b) A test at a volume of 5 liters at an approximate flow rate of 4-6 L/m has -25 ml. tolerances. A test of 10 liters at an approximate flow rate of 8-12 L/m has -50 ml. tolerances. A test of 20 liters flowing at approximately 18-22 L/m has -100 ml. tolerances. Criteria For the verification of tolerances of fuel measuring instruments, it is required that for the examined quantities of 5, 10 and 20 liters, the tolerances of each or the maximum-minimum ratio must be within 1 percent. Remarks For the verification of tolerances of fuel measuring instruments, it is required that for the examined quantities of 5, 10 and 20 liters, it is required that the variations are at ±1/2 or ±0.5% of each volume range. After the three tests, the following observations should be noted: 1.  A total of one instance of volume exceeding ±1/2 or ±0.5%, a new verification is not required, 2.  A total of 2-3 instances of volume exceeding ±1/2 or ±0.5%, a new verification is required. 107

SERVICE STATION STANDARD Considerations and follow up actions: a) If the verifications according to (1) (2) and (3) show correct results, and subsequently verified in (4) and (5) and show incorrect results, the Competent Officer will execute to prohibit the usage of the instrument and orders for a correction before an application for a new verification and certificate b) If the verifications according to (1) (2) and (3) show incorrect result, the Competent Officer will execute to prohibit the use of the instrument and will file for litigation due to the incor- rect usage of the instrument which has incorrect dispensing quantity under Section 79 (liable to an imprisonment of not exceeding 6 months or a fine not exceeding 20,000 Baht or to both). If it is found that the instrument was altered to make the instrument inaccurate under Section 77 (an imprisonment of not exceeding 3 years and a fine not exceeding 120,000 baht) At present, service stations have 5-liter calibration bucket used to examine the accuracy conditions of fuel quantity of the dispenser’s measuring meter. The bureau suggests that a 20-liter measuring tank is also used for verification and to verify the accuracy of the meters. 3. Use of fuel measuring meter without a certification Using a measuring meter for the purchase/selling of fuel oil under Section 25 requires the instru- ment to have a verification mark. If the instrument does not have a verification mark, as prescribed in Section 70 (liable to an imprisonment not exceeding 6 months or a fine not exceeding 20,000 Baht or to both). Picture 5.86 Sealed strap must be in good condition 108

The certification mark is affixed on two locations: 1. On the measuring meter, and 2. On the housing of the dispensing unit and the sealed wrap must be in good condition, is not loosely fastened or broken. If it is defective, inform the concerned government officer immediately. The inspection commences with the Competent Officer requests a key to open the dispensing unit in order to inspect the verification mark affixed to the measuring instrument. As such, a key must be provided by the service station to the inspector. If the service station fails to provide facilities prescribed under Section 58, by claiming the key is not available, punishment under Section 82 (a fine not exceeding 5,000 Baht). 4. Repairing fuel meter In the cased that the instrument is defective or dispenses incorrect quantity of fuel oil, the service station must ask for the service of the repairers holding Weighing and Measuring Instru- ments repairing license. Inquiry on the licensed repairers can be made with the Central Bureau of Weights and Measures or a Branch Bureau or staff of PTT Plc. 5. Relocation of the fuel measuring meter requires new certification Pursuant to the Thai Royal Gazette on “Determining types of permanently-fixed, Weighing and Measuring Instruments, having been verified and moved to a new location, therefore requires a new recalibration test”, announced on the 26th October 26 B.E. 2552 (2009). Upon the relocat- ing or repositioning of a measuring instrument, fuel oil or a dispensing unit to a new location, the owner of such instrument must inform in writing the Central Bureau of Weights and Measures or Branch Bureau within 15 days from the date when installation is completed to allow the Competent Officer to make a verification of the instrument before its usage under Section 25 Paragraph One of the Royal Act B.E. 2552 (2009). Incompliance is liable to punishment under Section 73 of The Weights and Measures Act B.E. 2552 (2009) (a fine not exceeding 10,000 Baht at beginning the 25th December B.E. 2552 (2009). Remarks The measuring meter having been installed/located at the service station. (1)  For an instrument having Primary Standards or new from the factory, inform the Central Bureau of Weights and Measures, but no new verification required (2)  For an instrument having Secondary certification performed at the station, inform the Central Bureau, and to perform recertification (3)  For the switching/moving/rotation of the locations of the meters, inform the Central Bureau, and to perform recertification 109

SERVICE STATION STANDARD 6.  Examination of dispensing volume discrepancy The service station manager must inspect fuel flow accuracy at the dispensing units at least once every month and compiles the PTT PM 01 report, using a standard 5-ltr. calibration bucket with every nozzle. If the discrepancy is above the tolerance level, he must inform the service station maintenance center. Follow the inspection instructions: 1) Place the calibration bucket on a level pavement in a safe working area, 2) Set a discharging amount at the dispenser (5 ltr. is required), 3) Put the tip of the spout at the mouth of calibration bucket, 4) Squeeze the nozzle trigger to release fuel at a rate of 4-6 liter per minute 5) When the dispenser shuts off the fuel, let go off the trigger (do not shake the spout with force) and allow fuel to drop inside the calibration bucket, 6) Put the nozzle handle back into the socket, 7) Read the fuel level on the 5-ltr bucket’s sight glass markings. If the level is above or below the targeted amount, repeat the 1-7 instructions three times (make sure that you completely drain fuel in the tank as even a small amount could cause excess level during every test), 8) Record the level in the meter reading form (pump testing), 9) If the discrepancy is exceeds ±50cc, contact the service station maintenance center 10) If the dispenser is tested to find suspected discrepancy, the test requires 5L, 10L and 20L of products at a similar flow rate respectively, by using the same 5L calibration bucket to accumulate the volume to reach the desired volume, and add the discrep ancy together from each 5-Ltr set at the end of the process. Interpret the result ac cording to Item 2 (5). Record the results into the meter reading form. Reading Point Reading level Picture 5.87 - 5 ltr.

SERVICE STATION STANDARD 5.2.4.2 Underground tank (UGT) UGTs are an important main equipment of a service station and serve as storage of products for selling. Inefficient UGT system can affect product quality, resulting in the lower quality than the expected standards. In addition to the UGT, the system has the following components, namely the pipes and their caps, dipstick and gauge hatch, suction pipe and ventilation pipe. Proper usage and good maintenance are essential in maintaining PTT product quality. Fire preventions provide safe environment to the dealers, staff, customers and members of the public. 5.2.4.2.1 Underground tank inspection 1) The pipe caps are properly closed and secured with a padlock at all time, 2) Dipstick hatch and manhole covers are firmly closed at all time, 3)  The Dipstick hatch cover O-ring seal must be in good condition, 4)  Check water level in the tank every morning before retail service begins and/or every shift changing, 5)  When using the Dipstick to gauging water or product level in the tank, the stick must be lowered slowly to avoid the impact that can damage the tank’s bottom, 6)  Each morning, wipe water or fuel residue inside the Dipstick hatch or man hole cover with a towel until dry, 7)  A designated receiver must be present to supervise the product unloading process from the tank truck to prevent wrong type of product unloading, 8)  Fire extinguishers are ready throughout the unloading process. Smoking is prohibited within a range of 15 meters 9)  During the unloading, the hatch of the Dipstick pipe must remain closed. Fire accident happened in the past when this was not observed. 10) Selling of the product must be suspended from the tank to which that product is being unloaded. Service can resume at least 20 minutes following completion of the unloading. Picture 5.89 Diagram of main components Picture 5.90 UGT’s Dipstick hatch. of an underground tank 112

5.2.4.2.2 Draining water from the UGT 1) If water level inside the tank is above 2 inches or 5cm, it must be drained out immediately with a hand pump or pitcher pump (water contamination is strictly disallowed in a gasohol tank), 2) Connect a small suction pipe of approximately 1/8 inch in diameter with one end tapered to a hand pump. Lower the suction pipe down until it is reaches the tank’s bottom, 3) Attach a rubber hose to the pump’s outlet and put the other end of the hose in a fairly big bucket, 4) Manually operate the pump to suck out water into the tank as prepared according to Item (2) 5) Drain water out until oil-water mixture appears. At this point stop the pumping immediately, 6) Remove oil from the water in the bucket. Put it in a container for contami- nated fuel 7) Transfer fuel-free water from the bucket to an oil separator of the station. 5.2.4.2.3 Inspection and closure of fill pipe caps The fill pipe caps must be closed properly and secured with a padlock at all time to prevent fuel vapor leaks as well as dirt, sand, leaves or water from entering the fill pipe. Fill pipe caps inspection - Inspect the caps every time the pipe is used to unload products, - Check the following parts of the caps: - The pipe threads are not worn out, - The cap padlock latch is not damaged or broken - The gasket is in good condition - The padlock ring is not broken - When the unloading process is completed, close the caps, check that they   fit the base properly and secure them with a padlock immediately. - If any part of the fill pipe is damaged, contact the service station maintenance center. 5.2.4.2.4 Removing water or fuel from Dipstick sump During the morning checks of water/fuel level, see whether there is water or oil residue inside the dipstick sump. If so, use a cloth to remove it until the sump is completely dry. If unattended, when it rains, the rainwater will rise to the point where it could seep inside the UGT through dipstick pipe. Follow the instructions to remove water from the access manhole: 1) Open the cover of the dipstick sump, 2) Use a piece of cloth to remove water or fuel from the dipstick sump. Transfer the water or oily water into a suitable small bucket or fuel can respectively.

SERVICE STATION STANDARD 5.2.4.3 Automatic tire inflator A tire inflator is an important equipment available at service station that customers make use of regularly. Therefore, it requires proper care and maintenance Picture 5.91 Tire Inflator Basic maintenance of automatic tire inflator 1) Perform a daily check of the inflator’s air chuck to make sure that it is tightly fastened to the air hose. 2) Keep the air hose into its place after every use, 3) Check tire pressure digital display for errors. 4)  Clean the housing, display screen and air hose daily. 5) Look for suspected leakage at all connections/joints. 6) Make a daily check that the nuts securing the inflator casing to the base are secure. See that the ground wire is firmly fixed. 7) Check that the circuit breaker’s cable connections are property installed to prevent overheating and sparks. A weekly check of the con nections and the insulation resis- tance is required. 8) Perform a weekly leak testing of the breaker to confirm it is still working normally. 114

Replacing the air chuck 1)  Switch off the tire inflator before replacing any equipment. 2)  A damaged or leaking air chuck must be replaced to prevent it from causing inaccurate pressure delivery. 3)  Cut a damaged air chuck at a point approximately 15 mm from the hose clip lock. 4)  Put a new clip lock on the hose. 5)  Insert a new air chuck in the hose. 6)  Use pliers or steel cutting pliers to press both ends of the hose. Be careful not to hurt your fingers (if using a clamp, screw it only moderately tight, since tightening clamp too much could damage the hose) Precautions - Do not drag the hose on the pavement. - Do not throw the air chuck. - Do not run over the hose.

5.2.5.6 Personal protective equipment (PPE) Safety facemask Hard hat Anti-chemical glasses Safety Vest Explosion-Proof ashlight Disposable Nitro gloves Anti-cut gloves/leather gloves safety shoes 127

SERVICE STATION STANDARD Personal Protective Equipment (PPE) is one of many methods employed to protect the employee from danger in the workplace. However, staff must bear in mind that PPE is a measure of last resort, useful only when the accident or danger has already happened. It does not eliminate the cause of danger or the risk of accident. It is highly recommended that staff find the root cause of danger and eliminate it effectively - rather than relying on PPE - so they have safe working environment. A case in point is leather gloves which prevent electrocution, but if we fail to repair a malfunctioned electrical equipment, the risk will persist and it could strike us on the day we forgot to wear the protective gloves. General instructions on the use of PPE 1. All company staff must dress to suit their line of works and wear PPE the company issues to them, according to operational safety standards. 2. The contractor(s) on assignment at the service station must wear suitable clothes required of their works and wear PPE according to the maintenance department’s safety standard. The station manager can suspend the works until they use PPE in line with company regulations. PPE selection process 1. Study tasks process and determine the underlying risk factors. 2. Choose PPE that has the right quality to prevent specific danger associated with the tasks. 3. Pay attention to the material used in the making of each PPE to make sure that it is effective against potential danger. Consult your supervisor, the service manager or safety personnel for more Information if necessary. Example of PPE selection Task: Using acid/alkaline agents in cleaning the toilets. Possible danger: agents could burn the skin at exposure location, such as hands and feet. Applicable PPE: Gloves (you have options of : rubber, leather and fabric gloves), and boots (you have options of rubber or canvass boots), PPE quality considerations: Leather and fabric gloves are unsuitable to a job involving water. Rubber gloves are most suitable. Likewise, canvass boots have their limitations similar to the gloves, so rubber boots are a better choice. PPE usage requirements 1. Once a PPE is selected, check its condition before using. Do not use damaged PPE. 2. If unusual situation arises while doing the job, for example while pouring chemical agent, it causes the rubber gloves to swell and puncture, you must stop the work, discarding the PPE and report to the service station manager. 3. When job is finished, keep PPE in storage. Do not leave it exposed to the elements which could adversely affect its quality. 4. For proper use of PPE, you may consult, “Recommendations on the use of PPE” in this document. 128
