PHOENIX (AP) - A two-alarm fire tore through a site where metals and compressed gases are stored, sending up thick, black plumes of smoke over Phoenix.
Phoenix Fire Department officials said the fire was under control but still smoldering nearly three hours after crews first arrived at the scene Thursday.
The cause of the blaze was unknown, but authorities said two employees of a plumbing supply company were doing welding work when the fire broke out just before noon.
A fire spokesman says the blaze consumed three structures in about 20 minutes. He said one employee of the plumbing supply company suffered minor burns but no other injuries were immediately reported.
Phoenix Fire dispatched more than 50 engines and other units to the blaze.
Phoenix police Sgt. Trent Crump said people in surrounding businesses were being asked to evacuate.
