The U.S. Department of Transportation (DOT) requires bobtail drivers to inspect their vehicles before operating them each day. Vehicles must undergo monthly, annual, and five-year inspections. In addition to conducting and documenting regular vehicle inspections, is your ability to safely operate your vehicle and pay close attention to your driving duties.
After completing this module, you will be able to:
Walk-Around and Pre-Transfer Inspections
Performing a walk-around inspection of your bobtail after loading at the bulk plant minimizes the risk for system or documentation issues when arriving at the delivery site.
49 CFR requires you to visually check the cargo tank emergency discharge system, delivery hose and hose assembly, and emergency discharge control equipment every day before transferring propane.
You may choose to perform your pre-transfer inspection either at the same time as your daily pre-trip inspection or before unloading at your first customer’s location.
After loading, perform a walk-around inspection to verify your bobtail is in safe operating condition. Make sure:
If all items are in safe operating condition, remove the chock blocks from the rear wheels, stow them in their transport rack or box, and proceed to your first delivery location.
Disengage the PTO.
Close the liquid and vapor internal valves.
DOT requires you to inspect the following components of your bobtail each day before transferring propane at customer locations.
Inspect the cargo tank discharge system, including:
Inspect the delivery hose and delivery hose assembly, including:
Inspect the emergency discharge control equipment, including:
Note: You must not transfer propane or operate your bobtail until you have completed a daily pre-transfer inspection and made sure any necessary repairs have been made.
DOT requires bobtail operators to check the components of the cargo tank discharge system to ensure they are in proper working order and that all connections are secure. You must not begin transfer operations if you find any of the following defects in the cargo tank discharge system.
You must check for:
You are required to inspect the delivery hose and its assembly every day as you unwind the hose prior to each transfer. If you find any of the following defects in the delivery hose or assembly, then you must not begin transfer operations. Check for:
Always remove from service immediately any hose with signs of unusual abuse, such as stretching, kinking, or flattening by a vehicle.
Bobtails can be equipped with two types of emergency shutdown systems.
You must not begin product transfer if operating levers, cables, rods, or switches are broken, severely corroded, seized, or otherwise damaged. Be sure to visually inspect fusible elements.
Off-truck remotely activated systems
You must not begin product transfer if:
Off-truck remotely activated systems cont.
When testing a wireless transmitter or receiver, have the cargo tank in sight and stand at least 150 ft from it. You must inspect emergency discharge control equipment within 18 hours before the first delivery of the day to ensure they are working properly.
NOTE: Follow your company’s policies and procedures related to pre-transfer inspection requirements for remotely activated systems.
Monthly, Annual, and Five-Year Inspections
DOT requires any competent person designated by the vehicle’s owner or operator to perform and document a monthly bobtail inspection.
Monthly vehicle inspections provide an opportunity to:
The items to check during the monthly bobtail inspection are the same as the daily pre-transfer inspection except for the following important differences:
Note: Some propane marketers include additional items in their monthly bobtail inspection programs, so be sure to check with your supervisor.
Inspecting the delivery hose and its assembly requires examining the full length of the hose and its connections and fittings. The hose must be pulled away from the hose reel and examined to determine if any of the hose rejection criteria are present. A unique delivery hose assembly identification number should be verified during the inspection.
Follow the steps below when completing the monthly examination of the delivery hose and its assembly:
The inspector is required to document the results of the monthly inspection and provide a copy of the inspection form for the company’s vehicle maintenance files.
Address any defects noted according to your company policy.
Annual and Five-Year Cargo Tank Inspections
The cargo tank must be appropriately marked with the annual and five-year pressure test dates.
Safe Driving and Handling Emergencies
In addition to conducting regular vehicle inspections and proper maintenance, your commitment to operate your vehicle safely and pay attention to your driving duties is critical. In the last course, you learned how to handle and report accidents and emergencies with no propane leak. Now, we’ll present how you should handle accidents and emergencies with your bobtail when there is product release.
Accidents and fires involving propane do occur. This lesson provides several reminders to ensure safe working conditions when you deliver propane and prepares you to work with emergency response personnel to appropriately address dangerous and unexpected situations.
Note: Each emergency situation is site specific and will vary based on the type of scenario you may encounter. So while it is important to always follow your company’s policies, there are basic guidelines to help you.
Safe driving practices benefit drivers and the public. They are essential for anyone who operates a CMV, and are particularly critical for propane drivers who transport hazardous cargo. It’s crucial for bobtail drivers to be alert, maintain vehicle control, and stay focused during daily deliveries.
Consider the following:
Consider the following (cont):
Note: When released to the air, one cubic foot of propane liquid will expand to approximately 270 cubic ft of vapor. Staying alert and driving safely are ways to keep you from causing a potentially deadly propane leak.
An emergency exists any time an unintended or uncontrolled release of LP-gas or any other hazardous material occurs during transportation or loading and unloading operations. Follow these guidelines when an accident causes a propane leak, while en route in your bobtail:
Propane bobtails are top heavy and the effects of side-to-side surge can contribute to rollovers. Pay very careful attention to the road and make every attempt to avoid any type of accident. Ask your company supervisor about the best way to avoid a rollover based on the terrain in your driving area.
If you are involved in a rollover, follow these guidelines:
