A Leaking Drum at the Dock
During unloading, a 55-gallon drum of a Class 8 corrosive (PG II) tips and its bung loosens. Liquid is pooling on the concrete dock, roughly a 3-foot puddle, and you can smell a sharp odor. The dock has a spill kit with absorbent, a neutralizing agent, and PPE. Two dock workers are standing about 10 feet away, one holding a phone. The shipping paper is in the cab. You are the only hazmat-trained person present.
1. What are your first actions, in order, and why?

First, protect people: move the two workers back and away from the puddle and the vapor, and keep others from entering the area. Second, eliminate ignition and other aggravating sources - for a corrosive, the immediate concern is exposure and reaction, not fire, but you still keep the area clear. Third, identify the material from the shipping paper (proper shipping name, class, UN number) and check the ERG for the guide number so you know the exposure and reaction hazards before you touch anything. Fourth, don PPE from the spill kit before approaching. Only then do you consider containment - diking or absorbing the puddle and, if the SDS/ERG and the kit's neutralizing agent call for it, neutralizing per the kit instructions. The sequence is people, information, PPE, then product - never the reverse.
2. The worker with the phone asks whether to call 911. How do you decide, and what do you tell them?

Decide based on whether the spill is within your ability to control safely and whether anyone is injured or the material is spreading toward a drain or the public. A 3-foot puddle of PG II corrosive that you can contain with the on-site kit, with no injuries, is generally a controllable incidental spill - but you don't guess. If it's reaching a drain, if vapors are affecting people, if anyone is exposed, or if you're unsure of the material's behavior, you call. Tell the worker: hold the phone ready, but don't call yet if the spill is contained and no one is hurt; if it spreads toward a drain or someone is exposed, call immediately and report the material, quantity, and location from the shipping paper. The judgment is to set a clear trigger for calling rather than a vague 'maybe.'
3. After cleanup, what reporting obligations might apply, and what do you record?
Read the worked answer
A small incidental spill that you contain and clean up on site with no release to the environment and no injuries may not trigger a formal release report - but you don't assume. You record the material (name, UN number, class, quantity), the time and location, what was released and how much, how it was contained and cleaned, who was present, and any exposure. You check with the shipper/consignee and your company on whether the quantity or circumstances require a report, and you preserve the shipping paper. If the material reached a drain, soil, or water, or if anyone was exposed, that changes the analysis toward reporting. The exam point: cleanup isn't the end - you document and you determine reporting, you don't just mop and move on.
