Pipeline, Port, and Marine Hazmat Incidents
Pipeline leaks, rail-to-port transfers, vessel cargo, intermodal containers, fuel terminals, docks, and waterfront industrial hazards.
What This Incident Looks Like
Pipeline and port incidents sit between transportation hazmat and fixed-facility hazmat. A product may be moving through a pipeline, sitting in a marine terminal tank, loaded in an intermodal container, transferred by hose, or carried on a vessel. Access is often difficult, water rescue may be part of the problem, and agencies can multiply quickly: fire, law enforcement, port authority, terminal operator, Coast Guard, environmental agencies, pipeline operator, railroad, EMS, and emergency management.
The first-due company should avoid treating these calls as simple leaks. Pipeline incidents can involve high pressure, remote shutoff delays, migrating vapors, ignition, and large exclusion zones. Port and marine incidents can add container stacks, shipboard spaces, oxygen deficiency, fumigants, refrigerated containers, fuel transfer, and runoff into waterways. Command needs product identity, operator contact, transfer status, wind/tide/current, ignition risk, and evacuation or shelter decisions early.
Recognition Clues
- Pipeline markers, odorant smell, dead vegetation, hissing, bubbling water, vapor cloud, or fire jet
- Dock, terminal, vessel, rail spur, tank farm, or intermodal yard with chemical, fuel, or container cargo
- Shipping papers, container markings, placards, UN numbers, bill of lading, or port terminal records
- Worker report of transfer hose failure, valve problem, overfill, container damage, or shipboard alarm
First-Due Actions
- Establish a large initial isolation area and keep ignition sources out of suspected vapor zones
- Contact the pipeline operator, port authority, terminal operator, or vessel representative through command
- Use ERG and shipping/container information while waiting for operator or cargo-specific data
- Protect waterways and storm drains early; marine and port releases can become environmental incidents immediately
- Build unified command with responsible operators and agencies as soon as practical
Do Not
- Do not attempt to operate pipeline valves unless directed through the operator and SOP/SOG
- Do not walk into low areas, ship holds, containers, or enclosed spaces without atmospheric monitoring and rescue plan
- Do not assume the container placard tells the whole cargo story
- Do not let runoff or foam solution enter water without environmental coordination when control is possible
