Update 7:30 p.m.: Authorities have still not suppressed the fire, said Jody Duncan, a MetroSafe spokeswoman. Once the fire is suppressed, authorities will investigate the scene to decide whether to lift the shelter-in-place and evacuation orders.
Meanwhile, Duncan provided updated information on the condition of the three workers hospitalized in the fire. One is in "extremely" critical condition, one is "seriously" critical and the other is listed as critical, Duncan said.
