At the time of a deadly explosion on
Monday morning at an Eni oil depot at Calenzano near Florence,
two separate maintenance operations were ongoing at the
facility, investigative sources said on Friday.
One was taking place at one of 10 platforms, the number 7 next
to platform 6 of the site's loading area and concerned a supply
line to load oil on tanker trucks.
The other operation instead was to repair two vapour recovery
units - a smaller and a larger one - which were not functioning
properly and which were located on platform 6 where the blast
occurred, killing three tanker truck drivers, two maintenance
workers and injuring nine others, investigative sources said.
