A fire temporarily interrupted work Friday morning at Elster American Meter when roof insulation caught fire.
John Shrader, second assistant fire chief, said some insulation caught fire during roof maintenance at the property prior to 9:40 a.m.
Employees evacuated just as practiced in a fire drill last week. There were no injuries and no significant property damage, said Chris Sheppherd, senior legal counsel for the company.
Shrader, incident commander, said workers extinguished the exposed fire with portable extinguishers, but could not access below the roof cover.
He said the fire department's thermal imaging cameras, used from below and above the roof, showed the fire had spread beneath the metal roof sheeting.
Shrader credited American Meter for calling the fire department right away. He said it was tough, physical work to remove the roof metal and expose hots spots, but it was necessary to remove the fire threat.
At 10:05 a.m., firefighters made a second call for additional manpower.
Shrader said he wanted to make sure there were firefighters on hand to give others a break.
By 10:31 a.m., fire crews continued to work on a roof operation for hot spots.
Interior crews had left the building at 11:14 a.m., about 90 minutes after the initial call was dispatched.
