Washington County, Ore. — Firefighters were called to a barn fire at 2:43 a.m. Monday in Helvetia.

Crews from Tualatin Valley Fire & Rescue, Hillsboro Fire & Rescue, and Bank Fire District all responded to the fire in the 9000 block of Northwest Dick Road.

A neighbor called 911 after seeing flames coming from the barn.

It took crews about 40-minutes to gain control of the fire.

It’s not clear what caused the fire.

The barn owner says it was primarily used for hay storage, but also housed a tractor and other farm equipment that was damaged.

The fire occurred in a rural area that does not have hydrants. Four water tenders carrying 3,000 gallons of water each were dispatched to the scene to provide a constant supply of water for fire attack crews.  Tualatin Valley Fire & Rescue has water tenders strategically placed throughout the fire district to respond to areas where there are no hydrants. TVF&R also works collaboratively with its fire service partners to utilize water tenders region wide in areas where service areas meet.
