BOZEMAN, Mont. -

Montana State University closes Sherrick Hall after workers pull tiles with asbestos.

Sherrick Hall is the home of MSU's College of Nursing.

The building is located just west of Montana Hall, off the Malone Centennial Mall on South 11th.

According to the school's website, Sherrick Hall was constructed to house the nursing program in 1973.

Folks with MSU clear out all of Sherrick Hall and lock the doors.

While only a small area was effected, representatives with the university tell me, they've shut down the entire building for safety.

"We stopped work and we closed the building," MSU Spokesperson Tracy Ellig.

Ellig tells us a crew was removing floor tiles to put down new carpet when they double-checked their records.

Turns out, they pulled the wrong files. They pulled the files for Herrick Hall, which does not have asbestos.

"It was a simple human error, someone grabbed the file for Herrick Hall, not Sherrick Hall," explains Ellig.

It's why they gave workers the go-ahead to replace the floor with carpet in Sherrick Hall. Ellig tells us they've taken both airborne and surface samples and sent them out to a lab on the east coast.

"Because this tile is very durable, it's hard to break and it doesn't crumble very easily, we anticipate that the likelihood of exposure is extremely low," says Ellig.

We wanted to learn more about asbestos so, we stopped by the city-county health department to speak to folks with environmental health.

"Everyone has gotten some kind of exposure to asbestos, most likely," says Gallatin City-County Health Department Environmental Health Director Tim Roark.

Roark has done his fair share of asbestos inspections.

He tells us the danger with asbestos is when it because friable or easily crumbled. Roark says that's when the long, thin fibers are released and the mineral can be inhaled.

"As long as you don't disturb it, those fibers are in tact so, you're not in danger of breathing them but, once you start sanding it, cutting it, making dust or disturbing it, that's when the dust arises, that's when you're in danger of inhaling," explains Roark.

It's why the floor tiles at Sherrick Hall were considered safe until workers started to remove them.

Roark says Asbestos has been linked to lung cancer, mesothelioma and asbestosis, a congestion in the lungs.

Workers have begun a deep clean of Sherrick Hall. Once they're done, Ellig says they'll run more tests just to make sure the space is completely clear of asbestos.

Ellig tells us, they hope to have the results to those tests Wednesday. Depending on the results, students, faculty and staff could be back in the building as early as Wednesday.

Until then, classes will be held in other buildings around campus.
