Dock Decision: Shipping Paper That Doesn't Match the Drums
At 07:15 you back into dock 4 at a paint and coatings warehouse to pick up a pre-loaded 53-foot van. The shipper's clerk hands you a shipping paper whose basic description reads: UN1993, Flammable liquid, n.o.s. (contains ethanol), 3, PG II, 24 drums, 9,600 lb. Walking the load, you see every drum marked UN1170, Ethanol, 3, PG II. One drum also bears a CORROSIVE subsidiary label that appears nowhere on the paper. The emergency response telephone number field is blank, the shipper's certification is unsigned, and the clerk says, "Just pencil in a number, everybody does it." The trailer already carries FLAMMABLE placards on both sides and the rear door; the front bulkhead has none. The clerk is under pressure because the dock closes at 08:00, and dispatch is calling for you to roll.
1. Do you sign for and move this load as it stands? Describe what you do on the dock, in order, and explain why each step matters.

No. You hold the load.
- The description does not match the packages. The shipping paper is the legal description that drives placarding, segregation, and the emergency response guide used by firefighters. If the drums are UN1170 Ethanol, the paper must say so; a generic n.o.s. entry with a technical name is only proper when no specific name applies. You cannot know which is correct, and you are not the shipper.
- The stray CORROSIVE label is unresolved. Either the drum is mislabeled or it contains a hazard class missing from the paper. Either answer changes the hazard class, the placards, and the response information.
- The blank emergency number is a real defect. The number must reach someone who can give immediate response information at all times the material is in transportation, not a number you invent.
- The unsigned certification is missing. The shipper certifies that the material is properly classified, described, packaged, marked, labeled, and placarded.
Practical sequence: stop the loading, photograph the paper and the drum, ask the shipper to verify the product and issue a corrected, signed paper with a monitored 24-hour number, then re-check labels and placards before you sign the carrier receipt. Dispatch pressure is not a defense.
2. Assume the paper is corrected and shows only Class 3, PG II, 9,600 lb in non-bulk drums. What placards are required, where do they go, and could the shipper use a DANGER placard instead?
Read the worked answer
Required: FLAMMABLE placards on all four sides - both sides, the rear door, and the front bulkhead that is currently bare. Placards must be readable from the direction they face, not obscured by mud, and securely attached. Nine thousand six hundred pounds is well past the point where the 1,001-pound exception for Table 2 materials could apply, so the vehicle is placarded.
DANGER is not available here. The DANGER placard is an optional substitute used when a vehicle carries two or more Table 2 hazard classes - for example, if the drum really were corrosive and Class 8 joined Class 3 on the load. It may never be used for Table 1 materials, and it does not change anything on the shipping paper: the paper still lists every hazardous material and its class, and responders still read the paper, not just the diamond.
So the correct outcome for a single-class load is four FLAMMABLE placards. Adding the front placard is your job as the person who sees the trailer; the clerk's paperwork will not fix a missing diamond.
3. The clerk offers the shipper's office number, answered 08:00-17:00 Monday through Friday. Is that acceptable, and what are the alternatives?
Read the worked answer
Not acceptable. The emergency response telephone number on the shipping paper must be monitored at all times while the material is in transportation - nights, weekends, and holidays included - and the person answering must have immediate access to emergency response information and the ability to give it out. A number that rolls to voicemail after 17:00 fails exactly when a spill at 02:00 needs an answer.
Acceptable alternatives:
- A 24-hour shipper number staffed by someone with the response information.
- A contract emergency response service, with the contract number on the paper.
- The carrier's own monitored number, if the carrier has the required response information and the shipper authorizes its use; the shipper is still responsible for the paper being correct.
What is not acceptable is the driver writing in a personal cell number, a number that only refers the caller back to the shipping paper, or a "best effort" office line. If the number cannot be verified as monitored, the load does not move.
