Hillsboro Fire & Rescue and Tualatin Valley Fire & Rescue crews were called out at about 11:30 a.m. on reports of a fire alarm at the Sunset West Business Park off Northeast 25th Avenue.
Everyone made it safely out of the building, fire officials said, and there are no initial reports of injuries.
Firefighters found and extinguished the fire which was contained to a small area inside one of the companies, saying it involved “specialty materials commonly found in high-tech manufacturing.”
A HazMat team was called out to assess the potential impact that the specialty materials may have, which prompted fire crews to order evacuations of the nearby businesses.
Investigators have not confirmed a cause of the fire.
“Hillsboro Fire & Rescue would like to thank Tualatin Valley Fire & Rescue, Hillsboro Police, Metro West Ambulance, and Portland General Electric for their assistance.”
