Two people were injured Thursday night when chemicals inside a reactor container exploded at the Wacker Siltronics plant in Northwest Portland.

Portland Fire and Rescue said the two men working near the reactor suffered respiratory ailments after the explosion. They were treated at Legacy Emanuel Medical Center for what firefighters called non-life threatening injuries.

The explosion happened at about 9:25 p.m. at the plant, 7200 N.W. Front Ave., which produces semiconductor wafers. The reactor combines chemicals for the manufacturing process. The two employees were doing maintenance near the chemical reactor at the time of the explosion.

The explosion was isolated to one portion of the plant and only the area around the reactor was evacuated.

About four dozen firefighters, including the city's HazMat Team, responded and checked the plant for contamination.
