Fire crews were called to Portland, Oregon's Siltronic Corporation plant recently after an explosion injured two workers performing routine maintenance on a chemical storage vessel containing trichlorsilane.

PORTLAND, Ore. – Emergency crews rushed to a Portland, Ore. silicon factory Thursday night, after two people were injured in a chemical reactor explosion.

Crews received the call for assistance from the Siltronic Corp. plant about 9:30pm, The Oregonian reported.

A fire and rescue spokesman said workers were working with trichlorsilane -- which is used to create silicon wafers -- when it exploded.

The injured pair were taken to the hospital to be treated for minor respiratory problems, KPTV reported.

Points to consider:

Trichlorsilane (UN 1295) is a colorless fuming flammable, corrosive liquid with a pungent odor. Vapors are heavier than air. The material is highly flammable, ignites spontaneously in air, and reacts violently with water, steam, alcohols, acetone, light metals and moisture in air to generate heat and flammable and corrosive gases. For general operating procedures refer to the Emergency Response Guidebook, guide # 139.
