Can I Haul a Load I Find Out Is Hazmat at Pickup?
The dispatch sheet says general freight. At the warehouse, the bill of lading lists flammable paint. Ask the warehouse to pause the handoff and send both documents to dispatch and the fleet's safety lead. If the truck is already loaded, wait for the shipper to verify the freight and the carrier to confirm it can haul the shipment before leaving.
Have the shipper check the paperwork against the load
Take a shipment of paint declared under the ordinary hazmat requirements. The bill of lading reads UN1263, Paint, 3, II and lists 8 drums totaling 400 liters. Under the shipping description rule, those four entries give the identification number, proper shipping name, hazard class and packing group in that order. A bill of lading can serve as the hazardous materials shipping paper when it contains the required information.
Compare the name, identification number, packaging type, drum count and total quantity on the bill of lading with the loading record. If the paper lists 8 drums and the record shows 9, ask the warehouse and shipper to identify the extra drum. The shipper verifies the hazard class and identification number. Based on what they find, have the warehouse adjust the load or the shipper correct the paper. If the container is sealed, ask the site to check the loading records and externally visible information through its handoff process, then tell dispatch what it found.
Ask the carrier if the truck needs placards
The 400 liters is the volume of the paint. To determine whether the vehicle needs placards, ask the shipper for the gross weight, including the drums. Suppose all 8 drums are non-bulk packages with a combined gross weight of 1,200 pounds. This is the only hazardous material on the vehicle, and no other exception applies. Under the Hazardous Materials Table and Table 2 of the placarding rule, this Class 3 paint shipment requires FLAMMABLE placards properly displayed on both sides and both ends of the vehicle.
The Table 2 exception applies when its conditions are met and the combined gross weight of Table 2 hazardous materials on the vehicle is less than 1,001 pounds. If the vehicle carries other hazardous materials, have the carrier check the whole load. Look up the separate rules for Table 1 materials, bulk packages and cargo with special placarding requirements.
Under the highway placard handoff rule, the shipper provides the required placards unless the vehicle already displays them correctly. The carrier must wait until the required placards are properly in place before transporting the load.
Check the driver's endorsement and the carrier's license
The driver checks the CDL. This paint shipment requires placards. Under the CDL definition of hazardous materials and the endorsement rule, the driver hauling it in a non-tank vehicle must have the right class of commercial driver's license (CDL) and a valid hazardous materials endorsement (H). If you have a Class A CDL without the required endorsement, ask dispatch to send a qualified driver.
The carrier checks its license. According to the California Highway Patrol enforcement manual, carriers hauling hazardous materials that require placards in California generally need a Hazardous Materials Transportation License (HMTL). A for-hire carrier generally also needs the license when it hauls more than 500 pounds gross of a material that would require placards if shipped in greater quantities in the same manner.
Suppose this shipment drops to 600 pounds gross, meets the Table 2 exception and has no other cargo that requires placards. The vehicle does not need placards for this paint. A for-hire carrier still needs to check California licensing. Have the carrier check licensing exceptions, driver training and additional requirements for this route.
Check the emergency number and put the shipping paper within reach
When this paint is offered to the initial carrier for ordinary for-hire highway transport, the shipping paper must include the shipper's certification and an emergency response telephone number. Ask the shipper to confirm the number covers the actual load and is monitored throughout transportation. The person answering must know how to handle an incident involving the material or have immediate access to someone who does. A number that only takes a message and requires a callback does not qualify.
Under the highway shipping paper rule, put the hazmat shipping paper on top of the other documents or mark it distinctly if you carry them together.
At the controls, you must be able to reach it immediately while belted in. Keep it readily visible to someone entering the cab or in a holder inside the driver's door.
Away from the controls, keep it in the holder inside the driver's door or on the driver's seat.
If the warehouse is still checking the freight or paperwork, or the carrier has yet to confirm the placards, driver qualifications or license, wait until the issue is resolved and the transport arrangements are confirmed before leaving. If you see damaged packaging or suspect a leak, move away from the freight, notify the site and the carrier immediately, and follow the site's emergency procedures.
