More on the San Francisco Collapse From FF Close Calls

UPDATE: SAN FRANCISCO FIRE / STRUCTURAL COLLAPSE - NUMEROUS LINKS, VIDEO AND DOWN-LOADABLES

SF UPDATE:
A converter box had been installed at that San Fran warehouse to bypass the electrical meter which probably caused the fire...and they say that's a sign the building may have been used for marijuana growing or a clandestine lab. They are looking at the possibility that the converter box could not handle the electricity load and thus was the source of the fire. The fire in the single-story warehouse was first reported at 4:45 a.m. Thursday. As you know, a Firefighter was hospitalized with a broken leg and burns after being injured when a portion of a wall fell on him.
STRUCTURAL FIRE COLLAPSE---CLOSE CALL REMINDERS:

As found in the various "links" below as well as Chief's Dunn & Brannigans teachings, keep in mind what should be on the minds of any of us operating at commercial fires with similar conditions:
*Defensive fire
*Commercial building/probable engineered roof systems
*Parapet walls
*Extended operations (in the San Fran fire, the parapet fell 24 minutes after arrival) and it was a Type II warehouse (normally the building cannot withstand the total burnout of its contents).
