Within the rolling workshop of an aluminium and alloy production plant, a fire broke out above a bridge crane, on a double roof frame. The flames crept along the workshop beams where oil vapours had been deposited. Very quickly, around twenty staff members formed an improvised emergency response team and extinguished some of the flames. Firefighters took over once on the scene and brought the fire under control definitively. Thanks to the effective in-house emergency response organization, damage was limited to just the plant’s roof.
