Just after noon, Engine 343 and Chief 34 were dispatched for a reported garage fire . Units from the 4th Battalion arrived on scene at 3300 East West Hwy and found a mysterious package that exploded next to a car. The call was upgraded bringing the Bomb Team, Haz Mat teams and multiple units from other jurisdiction to the scene.  The crew from 343 assisted with evacuations of surrounding apartment buildings and several other tasks, while Chief 34 was accountability. After six hours of standing by, the incident was deemed under control and command began releasing units.....Update...The following day, the news began reporting that the "Bomb" had actually been an acetylene tank that was stored in the trunk of a car.  The owner had tried to "Air out the car" when the gases found an ignition source.  The owner had fled the scene and was at a house in DC.
