Leaking Sulfuric Acid Drum at a Rest Area
At 2:10 a.m., you stop at an Ohio rest area with your placarded trailer. During a walk-around, you see liquid dripping from the rear door and smell a sharp, irritating odor. Inside, a 55-gallon steel drum labeled UN1830, Sulfuric acid, 8, PG II, has tipped against another drum; the bung is loose and acid is pooling on the trailer floor and dripping onto the pavement. A storm drain is about 30 feet away. The rest area has 20 parked cars and an idling diesel pickup nearby. You have leather gloves, safety glasses, and a rain jacket, but no acid-resistant suit or respirator. The shipping papers are in the cab. You must decide what to do in the first few minutes.
1. What immediate actions do you take, and what do you avoid?

I would stop, keep the trailer closed as much as possible, and move people away from the rear of the trailer and the drip path. I would stay upwind and uphill, and I would not try to right the drum, tighten the bung, or wipe up the acid with the gloves and rain jacket I have. Leather gloves and a rain jacket are not acid-protective equipment, and a concentrated acid can burn through them. I would call 911 and report a hazardous-materials leak at the rest area, giving the location, the material, the UN number, the container size, the visible leak, the storm drain, and the nearby vehicles. I would keep the shipping papers available for responders and warn people not to drive through the puddle. I would not use water or a neutralizing agent unless trained and directed; that can make the situation worse. The priority is isolation, notification, and avoiding exposure, not cleanup.
2. What information should you give the 911 dispatcher and the responding firefighters?

I would give the exact rest area location and direction of travel, then identify the material as UN1830, Sulfuric acid, Class 8, PG II, in a 55-gallon steel drum. I would describe the leak: a tipped drum, a loose bung, liquid pooling on the trailer floor and dripping to the pavement, and the distance to the storm drain. I would give the wind direction and weather, the number of people and vehicles nearby, and whether anyone is injured or exposed. I would mention that the trailer is placarded CORROSIVE and that the shipping papers are in the cab. I would also tell them that I have no acid suit or respirator and have not attempted cleanup. Responders will want the ERG guide and the shipping-paper entry, but I should not delay the 911 call to look them up. After the call, I would notify my carrier and the shipper.
3. After the leak is controlled, what notifications and records should you expect?
Read the worked answer
I would notify my carrier's safety office and the shipper, and I would cooperate with the incident investigation. Depending on the severity, the carrier may have an immediate notification duty to the National Response Center and a written incident report obligation. I would not decide on my own that 'it was small' and skip notification; the carrier and the responsible official need the facts. I would preserve the shipping papers, note the time of discovery, the weather, the container condition, the response, and the names of officials on scene. I would not sign a statement that misstates the amount released or the cause. If I am asked to move the trailer before cleanup is complete, I would refuse until the responders release it. The driver's job after the emergency is to report accurately and not to obscure the record.
