Two fire engines and two fire rescue units were called to reports of a man stuck between a barge and a jetty in Chequers Lane, Dagenham.
The man was released before the Brigade arrived, but firefighters assisted London Ambulance Service Hazardous Area Response Team (HART) and the RNLI in bringing the man onto a landside jetty via another barge. He was then taken to hospital by London Ambulance Service crews.
Crew Manager Alan Jones, who was at the scene, said: “The man had been crushed between a barge and a pontoon.
“The barge had moved away when we got there and the man was on a gangway.
“We worked alongside London Ambulance Service and the RNLI to get him onto a splint and then hoist him up into another barge and into the ambulance.
“It was an unusual rescue and crews worked hard alongside emergency services colleagues to get the man safely into the ambulance.
"This incident shows how we regularly work together with partner organisations at a range of different incidents.”
The Brigade was called at 0729 and the incident was over for firefighters at 0901. Fire crews from Barking and Dagenham fire stations attended the scene as well as fire rescue units from East Ham and Bethnal Green fire stations.
