PORTLAND, Ore. -- The building housing Dosha Salon on Northwest 23rd Avenue and Glisan Street that was damaged badly in the gas leak explosion last week will be demolished.

The City of Portland confirmed that the owners have applied for a permit to demolish, and the permit has been approved.

Investigators from OSHA and NW Natural were at the blast site Wednesday.

A Department of Environmental Quality spokesman said asbestos levels were not a cause for alarm, according to the air monitoring equipment in place.

Asbestos abatement is underway now, managed by an outside contractor.

Meanwhile, businesses that sustained minor damage were still cleaning up.

Portland Bagel Works, which was housed in the building that exploded, said he's still coming to terms with the idea that his business is gone.

"For as many hours as I worked there every day," he said, "for it to be suddenly gone, it's going to take some getting used to."

Deborah Haynes, owner of Blush Beauty Bar & Salon, located across the street from the site of the explosion, said she hopes to reopen Nov. 3.

"That's my goal," she said. "We've got a lot of cleaning that needs to happen, not all of our windows will be replaced, but our doors will be replaced."

Ritual Adornments, a jewelry and jewelry-making materials store, faces the daunting task of cleaning thousands of pieces.

It will be months before they can open again because of structural and water damage to the building.

Ritual Adornments will be closed for months after the blast, due to damage to the building.
