All personnel at Pembroke Refinery will gather together for a private remembrance and period of silence today (Friday) to remember the tragic incident which took the lives of four contractor colleagues, also seriously injuring a fifth, on June 2, last year.

Neighbouring industrial sites surrounding the Haven Waterway will also mark the silence at 1.30 pm.
