Several businesses were evacuated, and four people evaluated, after carbon monoxide was detected Monday afternoon at Columbia Square, the strip mall anchored by Chuck’s Produce in east Vancouver.

Emergency crews were dispatched at 4:25 p.m. to 13215 S.E. Mill Plain Blvd. Readings revealed carbon monoxide levels were above normal, Vancouver firefighter-spokeswoman Eva Scherer said. The four people evaluated for symptoms of exposure declined transport to a hospital.

The call originated from an alarm at a Supercuts barbershop, and nine businesses were affected, Scherer said. Chuck’s Produce was not among the businesses evacuated.

An “oily” or exhaust-like odor was reported, said Bob Sisson, owner of Kazoodles toy store at the east end of the shopping mall. Sisson said it appeared the issue started inside a vacant storefront near Supercuts. Workers left the space about 3:30 p.m.
