Employees at the Home Depot at 355 Marketplace Ave. in the Mountainview neighborhood called 911 at about 10:20 p.m. to report the fire. When firefighters arrived, the trailer was in flames in a loading dock and the fire had spread both inside and outside the warehouse, San Diego Fire Department Deputy Chief Steve Ricci said. Several propane tanks that were stored outside the warehouse exploded.
The first fire units called for additional help. They knocked down most of the flames in about 10 minutes. The fire caused the warehouse sprinkler system to go off and firefighters sprayed down the flames inside the warehouse, so there was both fire and water damage, Ricci said.
