Fire officials believe lightning from overnight storms caused the deck of a large two-story incinerator to catch on fire at a building near Woodstock.

The Woodstock Fire Rescue District responded around 5:23 a.m. Thursday to Vorteq Coil Finishers, 15920 Nelson Road in unincorporated Woodstock, for a report of a commercial building fire.

Alex Vucha, a spokesperson for the Woodstock Fire Rescue District, said firefighters arrived to find flames coming from an exterior wooden structure that surrounded a large two-story incinerator.

Firefighters had to establish rural tender and water supply operations at the roadway since the area is not supplied by fire hydrants, Vucha said.

Firefighters quickly engaged in a defensive fire attack and the fire was extinguished within five minutes.

A further investigation confirmed the fire was contained in the area surrounding the incinerator and remained on the exterior of the building. No damage was reported on the interior.

Investigators suspect that an overnight lightning strike caused the fire, but an investigation is ongoing, Vucha said, adding that the blaze is not considered suspicious.

A damage estimate was not immediately available. The wooden structure and incinerator were both damaged in the fire.

No fire personnel or civilians were injured during the incident.
