A federal report on a furniture store blaze that killed nine Charleston firefighters almost a year ago says crews responding never had enough water.

The draft report from the National Institute for Occupational Safety and Health released late Thursday says firefighters had too few hoses and not enough water volume.

The draft is one of several federal and city reports being issued on the fatal blaze and it sheds more light on the confusion that enveloped the Sofa Super Store on June 18 as the inferno spread.

The report includes details of what happened to the firefighters. Two of them found a pair of comrades in the smoke-filled showroom but lost contact as gases and combustible materials in the furniture store erupted in flames that filled the building.
