An operator raised the alarm seconds
before Monday's explosion that killed five workers at an Eni
fuels depot at Calenzano near Florence, investigative sources
said Tuesday.
It all happened at loading platform number 6 of the loading area
which has 10 platforms, they said.
At 10:21 and 30 seconds, the recorded time according to the
investigators, an operator pushed the alarm button but in a few
seconds there was the initial explosion, believed to have been
caused by a spark igniting spilled fuel.
This was followed by a chain of explosions involving at least
five tankers, the investigators said.
