A raging four-alarm fire ripped through a warehouse at San Francisco's Pier 45 early Saturday, sending thick, black smoke into the sky that could be seen for miles.
Firefighters responded to the massive blaze at 4:20 a.m. and quickly went into an offensive fight by going inside the warehouse. Officials said the intensity of the fire was so hot, they quickly raised the response to four alarms and evacuated the warehouse. A fireboat was also called to respond to the blaze.
Crews then started to fight the fire with a defensive strategy to protect other structures. Video showing the peak of the blaze shows a raging inferno, ripping through the warehouse. Portions of the warehouse roof also collapsed.
According to the San Francisco Fire Department, the fire was contained at 11:30 a.m. Saturday morning.
In a press conference, SFFD's Lt. Jonathan Baxter said crews may remain on scene possibly until Monday to make sure hot spots are out.
Baxter also said one firefighter suffered a severe laceration to the hand and was taken to the hospital. The firefighter is in stable condition and has been released from the hospital.
SFFD and San Francisco Port Authority confirmed an investigation will go into effect immediately to determine the cause of the fire and the integrity of the pier.
