Direct answer
The short answer for Washington, DC
In the District, federal freight courts, garages beside Metro tunnels, Anacostia outfalls, and service alleys on Embassy Row see generator diesel, remodel solvents, battery fluid, and unlabeled overnight totes. Security screening there can slow fire trucks. Move people away first. Pull the Safety Data Sheet (SDS) instead of letting porters try chemistry. Put barriers at inlets the District Department of Energy and Environment (DOEE) watches closely. DC Fire and EMS (FEMS) works with District environmental staff. Drums leaving through the security gate go with a waste shipping record. Under RCRA, the federal waste law, those drums may be regulated. Buildings with many tenants stay closed until air targets are written down.

Local planning context
Loading courts at federal offices, embassy service yards, and parking stacks tied to Metro stations create a District mix. Think diesel day tank transfers, lithium residue on charger decks, paint stocks for overnight renovations, and unlabeled vendor drums left next to the metal detector lines. Security often hears about a chemical smell near the freight door before anyone has an SDS. Clear the loading court and keep visitors at the screening line. Credential checks for fire trucks are real, so list escort contacts ahead of time.
Combined sewer overflows, where storm water and sewage share pipes, plus Anacostia outfalls and Rock Creek storm lines raise the District's reporting stakes when product leaves a pad. Rinsing the court before staff arrive can push product toward the Anacostia and into a District report. Follow DC Fire and EMS on whether to stay put or leave.
Building managers and federal facility contacts should share one plain script. It says which floors empty, which curb inlets are off-limits, and who walks engines through screening. Write down garage height limits and who holds dock badges. A hearing or a tour group does not speed up cleanup.
