Multiple explosions obliterated a fireworks warehouse Tuesday in northern California, causing nearby evacuations and power outages. The blasts caused several fires, sending black smoke into the air and forcing evacuations, authorities said. There were no immediate reports of injuries.People were urged to avoid the area of Esparto and Madison for several days following the Tuesday night explosion, which set off multiple fireworks and caused a large fire that led to other spot fires and collapsed the building.A large plume of black smoke could be seen from miles away and evacuations were ordered in the area.Crews responded to the fire just before 6 p.m.Cal Fire crews who were responding to a fire in Vacaville, about 25 miles away, told Sacramento sister station KCRA that they saw the smoke plume and began directing personnel that way. KCRA’s LiveCopter 3 was over the area and a number of fireworks could be seen going off amid the flames. Several explosions appeared to engulf some structures on the property. The fire also appeared to spark additional spot fires.One of the spot fires, which Cal Fire called the Oakdale Fire, spread across more than 78 acres of nearby vegetation before it was handled.The explosions also posed a danger to firefighters who responded to the area, and crews had to push back and let the fire burn as explosions riddled the facility for hours.In a press briefing just after 9 p.m., Esparto Fire Protection District Chief Curtis Lawrence said that crews would maintain a safe perimeter around the main fire throughout the night, while putting out spot fires around the area.Video below: Fireworks accident expert weighs in on fireworks facility explosion, fire The sheriff’s office said a one-mile evacuation order was put in place around the area where the fire was burning.
