TODAY marks the fifth anniversary of the Chevron refinery disaster, which saw four workers killed at the Rhoscrowther facility.

The blast occurred in a 730-cubic metre storage tank where maintenance was being carried out, killing Dennis Riley, 52, Robert Broome, 48, and Andrew Jenkins, 33, all from Milford Haven, and 54-year-old fireguard Julie Schmitz (nee Jones), 54,

from Pembroke.

Andrew Phillips, known to his friends as Pansy, suffered critical burns after the blast.

To mark the anniversary, Mr Phillips’ daughter-in-law, Milford Haven fitness instructor Millissa Fairbairn took part in the Edinburgh marathon, raising funds for the Wales Air Ambulance -– which she credits with saving her father-in-law’s life.

“I will always remember the explosions,” she said. “If it wouldn’t have been for the air ambulance Pansy wouldn’t have got to Morriston Hospital as fast as he did.”

Mr Phillips has since undergone treatment for post-traumatic stress disorder.

A major criminal investigation to consider offences of corporate manslaughter was dropped last year with a spokesman for Dyfed-Powys Police saying “no stone had been left unturned”, adding that the Crown Prosecution Service had decided there

was “insufficient evidence to proceed against any of the companies involved”.

In the wake of the blast, memorials to the victims were erected at the Rath, Milford Haven, and in Pembroke.
