Need a tank truck maintenance program to load safely


The Safe Loading Program and associated scheme apply to all trucks that load petroleum products and other hazardous products at facilities operated by major oil companies and ensure that all tank trucks and equipment are fully tested and maintained every six months in accordance with industry best practices. .

Ensuring that tank trucks are regularly checked and maintained ensures the safest possible entry, loading and exit from fuel loading facilities.

It also ensures the safety of commuters and other road users on the highway.

A Pass-2-Load inspection should be required for all tank trucks that deliver bulk oil, including main engines, rigid tank trucks, tank trailers, and trucks used to transport bulk oil within removable tanks. Transport companies without a secure loading card for their trucks should not access loading terminals.

The checklist for a safe program to load should look like this or it may be more comprehensive.

Driver’s checklist for loading and unloading procedures before loading the transport vehicle

(1) Guided tours:

A driver must perform a walking inspection. You should visually check for any unusual smells, noises, or physically defective equipment, such as broken springs, overheated tires, misaligned axles, leaks, smoke, etc. Before loading, check that each compartment is empty. If you charge on the product, you will be billed for the incident.

K-1 Kerosene: If you are charging K-1 Kerosene, step 2 is important. You should NOT load K-1 into a compartment that previously held gasoline. Only charge K-1 after a distillate. It is a mandatory practice to empty the compartment of all residual material before loading K-1.

Bottom loading procedures

(1) Stop delivery vehicles at the loading ramp stop line.

(2) At the shutdown line, turn off all lights, radio, and other electrical equipment (and follow any other local procedures posted by the factory).

(a) Check the tires and suspension for broken springs.

(3) If the rack is not disengaged, apply the parking brakes and shut off the engine.

(4) When the rack is clear, start the engine, pull forward and locate the truck for loading.

(5) Reinstall the parking brake.

(6) Stop the engine.

(7) Protective goggles and a protective hat must be worn at all times while transferring the product.

(8) Under NO circumstances should the driver leave the loading area, except in an emergency.

(a) No one other than the driver should be in the loading area

except:

(i) A certified instructor training this driver.

(ii) Persons authorized by the oil company who have a legitimate reason to be in this area during the loading process.

(b) No driver, while filling his truck, will allow his attention to be diverted from the loading process.

(i) Examples of activities which unnecessarily distract from the appropriate objective of the loading process are:

(a) Eat or drink

(b) Read or write

(9) If the truck is so equipped, check the product retaining lights.

(a) Connect the high level fiber optic cable (ground line / scully cord) to the truck.

(b) + Check permissive green light

(c) If the green light does not come on, stop the charging process, see instructions / factory attendant / or supervisor.

(10) Connect the vapor recovery hose and fully close the two cam lock levers (“ears”) on the hose.

(11) Open the mounting box and open the internal valves as needed.

(12) Connect the appropriate guide arms

When connecting a loading arm coupler to the trailer hose, slide the collar onto the adapter before operating the lever, which locks the collar and opens the valve. Do not force the collar with the lever cam. This damages the lever arm and the shear pin.

(13) Open internal valves as needed.

(14) Clear the registers and set the presets for the appropriate gallons for each compartment. Know the capacities of all the compartments of the truck. The preset counter should never be set to an amount greater than the legal / safe filling capacity of the compartment to be filled.

(15) Start the appropriate product pumps.

(16) At each meter:

(a) Check product, preset gallon amount, and loading arm connection to correct compartment.

(b) Activate the starting mechanism.

(c) Check that the preset countdown is working correctly.

(d) Check that there are no leaks.

(17) Observe the slow flow shutdown of all meters. If the slow flow does not engage at 50-30 gallons, immediately stop the flow by pressing the preset stop button. Do not bypass the slow flow. Report to management.

(18) After loading each compartment, close the internal compartment valve. When a compartment is filled beyond the safety fill capacity, the charging rack high level control monitor will not allow additional charging. If additional loading is required, the operator should follow local product drain procedures (which will include notification to factory management) so that the loading rack high level control monitor returns to a permissive state. On units with a built-in overflow indicator, it may be necessary to press a reset button to get a green LED on the rack monitor.

(19) When loading is complete, disconnect and store the loading arms.

(20) Make sure the drop heads are hooked and the lock bar is down and locked.

(21) Close the doors of the mounting boxes and secure them.

(22) Disconnect the vapor recovery hose. Secure the steam hose to its bracket on the bracket and lock the cam lock (“ears”).

(23) Disconnect the high level fiber optic cable and secure it. Remember, this is the first thing connected and the last disconnected.

(24) Look immediately to the right side of the truck to make sure all loading equipment has been unplugged and stowed in the correct position.

(25) Move the unit from the charging rack to the designated parking area.

(a) Apply the parking brakes

(b) Stop the engine

Do not leave the unit under the rack area after charging

(26) Report any spillage or malfunction of loading equipment to factory management.

(27) Collect bill of lading / invoice and all other necessary documents.

This procedure may vary for each charging terminal.

(28) Ensure that OSHA product identification labels and emergency response guide are available in the cab of the truck

(29) Note: These procedures may vary a bit from one charging facility to another. You need to familiarize yourself with the rules and regulations of each loading facility to do a good job.

P1176: Rear O2S correction limit obtained
Meaning
The resulting rear O2S correction limit is the generic description of the P1176 code. But the manufacturer may have a different description for your vehicle model and year.

O2 sensor defective
Defective MAF sensor
Vacuum leak on the engine
Lean air / fuel ratio
P1177: O2 correction behind catalyst B1 limit reached

O2 sensor defective
Defective MAF sensor
Vacuum leak on the engine
Lean air / fuel ratio
