Units from CAFD Stations 1 & 2 responded to a reported industrial fire at 00:38hrs on June 7, 2010.  Upon arrival crews were met by heavy smoke conditions on the 18th Street side of the building.  Crews made entry and found the #5 match machine heavily involved in flames.  The fire was quickly knocked down but due to the large volume of smoke in the building CAFD staff began ventilation operations and remained on scene for 2 hours.
