Crews from Unified Fire Authority and South Salt Lake snuffed an explosive late Wednesday morning blaze that heavily damaged six units in a storage facility at 3948 S. West Temple.
Unified Fire Battalion Chief Brian Anderton said the fire, reported after one of the units appeared to literally explode in flames about 10:45 a.m., was controlled by noon.
No one was in the unit when the blaze started.
The fire was listed as accidental, but the origin had not yet been determined, he said.
Among possible causes that were eliminated were whether the unit had housed an illicit methamphetamine laboratory or if a transient was illegally living there.
A man and a woman detained at the scene for questioning were arrested on outstanding warrants. Officials said the two appeared to have no connection to the fire.
No damage estimates for the six units were immediately available. In addition to the units themselves, investigators will have to take into account the value of any lost contents.
