OCEANSIDE–A fire early Saturday damaged a commercial building in Oceanside, the Oceanside Fire Department said. The blaze broke out just after 1:30 a.m. in a large building in the 300 block of Via Del Monte in Oceanside. Oceanside police were concerned about flammable liquids inside the structure that was producing significant smoke at the front of the building and pouring out a roll up door, according to Fire Battalion Chief Greg DeAvila. Once inside the building, fire crews were faced with heavy smoke conditions from the fire which extended throughout office space and a large commercial storage area for a local produce packing and distribution operation. Firefighters placed ladders to access the roof to cut heat holes and open up large steel roll up doors providing ventilation inside for crews completing a rescue search and control the fire. The contents burning inside the produce packing house involved heavy plastics, cardboard and machinery, but no large contents of flammable liquids were found. The fire was brought under control in approximately 26 minutes after the first units arrived at the scene. No victims were found inside the building. The damage has yet to be determined due to the unforeseen damage to office space and various contents in the storage area.
