A fire destroyed a wooden barn in a vineyard outside Windsor on Thursday evening.
Smoke from the fire, which was reported at about 7:22 p.m., could be seen from Santa Rosa.
The barn, which was used by Calplans Vineyard Management Company, was completely engulfed in flames when firefighters arrived at 8500 Eastside Road, said acting Battalion Chief Mark Dunn of Central Fire. Propane tanks on the side of the barn were spewing gas into the air, adding fuel to the flames, he said.
"The propane tanks were venting off and making a loud hissing sound," Dunn said. There was also a downed PG&E power line across the building.
Concerned the propane tanks might explode, firefighters pulled back and took up defensive postures around the building for about 10 minutes until the tops of the tanks melted off, Dunn said. Firefighters returned to the barn and contained the fire, which destroyed the barn and the vineyard equipment stored inside.
A second storage building, also used to store equipment, was damaged by the fire but most of the contents inside were unharmed, Dunn said. No one was injured.
Fire crews from Geyserville, Healdsburg, Forestville, Windsor, Graton, Santa Rosa, Rincon Valley and Cal Fire responded to the blaze. Eastside Road between Trenton-Healdsburg Road and Windsor River Road was closed for more than an hour while firefighters battled the blaze, reopening just after 9 p.m.
The cause of the fire is under investigation.
