Fire crews respond to ammonia leak at On Semiconductor
Gresham Fire & Emergency Services responded to a call about an ammonia leak around 8:30 a.m. Tuesday, July 20, at On Semiconductor in Gresham, 23400 N.E. Glisan St.
“A contractor cut a very small ammonia vapor line,” said Mark Maunder, battalion chief with the Gresham fire department.
He described the line as no bigger than a quarter-inch.
Two workers exposed to the vapor were checked out on scene and then transported to Providence Hospital in Portland as a precaution.
The leak was isolated very quickly, Maunder said.
