Fresno Fire continues its investigation following a massive warehouse fire on “L” and Hamilton just after 3 Thursday afternoon in southeast Fresno.

More than three dozen firefighters attacked the large flames from above and on the ground. “This warehouse was fully involved,” said Josh Sellers with Fresno Fire.

The giant plume of smoke grew and could be seen across the downtown Fresno skyline as fire crews responded. “While en route, there was already a large column of smoke that was visible,” said Sellers.

The high temperatures, coupled with overhead power lines, made the firefight uniquely challenging for crews. Fresno Fire confirmed that PG&E shut off the power in the area of the flames for safety reasons as fire crews knocked out the flames.

Fresno Fire rotated its crews to avoid heat exhaustion. Smoldering ash was all that remained of the building after the flames, which took crews about an hour to control.
