Milford Haven coastguards reported a “blast large enough to shake the windows” with “black smoke in the air”.
The Mid and West Wales Fire and Rescue Service sent 10 engines to the scene and brought the incident under control within an hour and a half.

Phil Horne Eyewitness
Eyewitnesses reported hearing a “massive bang” and saw plumes of black smoke following the blast.
Phil Horne was in his back garden in Milford Haven, on the opposite side of the waterway, at the time of the incident.
“I heard a large explosion, turned around and saw a large fireball disappearing into the sky,” he said.
“It went about halfway up the chimney stack of the refinery.”
Liz Herbert, who also lives on the other side of the haven, said: “I heard a massive bang and saw a huge plume of thick black smoke.
“It was really frightening.”
