Update, Sat., Oct. 22: Authorities say a fire that tore through an Ontario recycling center and sent up a cloud of smoke visible for miles is under control.
Crews are mopping up scattered flames on the sprawling property, located just west of Ontario International Airport.
Ontario Fire Captain John Sitar tells KPCC that cardboard and plastic fueled the flames, making it a long fight: "Think of a Duraflame log, and you it bring into your home and you light it, and it takes quite a bit of time for that to burn out. And so we had, if you would, many of those logs stacked upon each other."
About 200 people living nearby were evacuated and have since returned home.
Two firefighters were injured. One suffered a burn to the hand. Another fell and needed stitches. One bystander was also treated for smoke inhalation.
The Air Quality Management District has issued a smoke advisory for areas of San Bernardino County and Riverside County.
The cause of the fire remains under investigation.
