Investigators seek cause of oil depot fire in Britain
LONDON -- Investigators searched yesterday for the cause of a huge explosion Sunday at one of Britain's largest fuel depots, including the possibility that a tanker driver had accidentally sparked the blaze.
They also were looking into whether firefighters had enough equipment and training to deal with such an inferno.
The chain reaction of explosions at the Buncefield oil depot blackened skies as far away as France, and triggered a blaze that burned for days. Forty-three people were injured.
The Fire Brigades Union, which represents most British firefighters, accused fire authorities yesterday of not having enough foam and of not adequately training firefighters to tackle such a blaze.
''It was a catastrophe waiting to happen," said a union spokesman, Duncan Milligan.
A whistleblower at the depot, meanwhile, described multiple safety hazards to The Sun newspaper yesterday, and called the facility a ''ticking bomb."
But an official investigating the fire said he had had no ''grave concerns" about conditions at the depot before the blaze. The county's fire chief, Roy Wilsher, said the union's assertions were ''utter nonsense."
''The work of my firefighters and my officers has been magnificent," said Wilsher.
