This from Minas Klikas:
We had about 6-7 concrete trucks rolling after midnight . Was controlled with a full still response at 200 W. Jarvis, an Ozinga Ready-Mix yard.
Late Sunday evening, DPFD responded to several concrete trucks side-by-side that were fully engulfed in fire, with fire threatening power lines and close to a building. Quick action with multiple heavy streams by the Red Shift brought the incident under control.
