Leaking Acid Drum at a Truck Stop Fuel Island
You are parked at a truck stop fuel island when you notice liquid dripping from under a pallet in your van. You carry 20 drums of UN 1789, hydrochloric acid, Class 8, totaling 3,200 lb, plus general freight. One drum has tipped and its lid is seeping; a sharp odor is present and a small pool is spreading toward the fuel island drain about 15 feet away. The shipping papers are in the cab. The fuel island has two diesel pumps running for other trucks, and the diner is 40 feet away with people inside. Your engine is running. You have no spill kit and no protective clothing beyond leather gloves.
1. What are your immediate priorities, and what should you do first?
Read the worked answer
Treat this as a hazardous-material release, not a maintenance problem. First, shut off the engine, stop fueling operations, and keep ignition sources away. Do not touch the liquid or breathe the vapor; leather gloves are not adequate for hydrochloric acid. Evacuate the immediate area, move people upwind, and notify the station attendant and 911. Isolate at least 150 feet in all directions as an initial precaution and keep traffic away from the drain. Use the shipping papers to identify the material and consult the Emergency Response Guidebook. Do not attempt to stop, absorb, or wash away the leak without training and proper PPE. If the pool reaches the drain, tell responders immediately.
2. What information must you give responders, and where do you get it?
Read the worked answer
Give responders the shipping paper information: UN 1789, hydrochloric acid, Class 8, the number and size of drums, total quantity, shipper, and the emergency response telephone number. Also give your exact location, the amount leaking, whether anyone is exposed, wind direction, and what is nearby, including fuel pumps and a diner. The placards and the Emergency Response Guidebook help them choose protective clothing and isolation distances. Keep the shipping papers available; do not hand them off and leave.
3. If the shipper later stops the leak, can you continue the trip? Explain.

No. A leaking package cannot remain in transit. The drum must be repaired, overpacked, or transferred by a qualified person, and the truck may need decontamination before it can carry other freight. Placards stay on the vehicle until the hazard is removed. You should not reload the leaking drum or continue to the next stop as if nothing happened. The release must be reported by the shipper or carrier as required, and the vehicle should not be moved until responders or a qualified hazmat team says it is safe.
