Update 10:35am with additional details about the hazard and possible reopening time.

Technicians from General Electric are at the scene at SSM Imaging to help the Mehlville Fire Department vent helium gas from an MRI machine at the medical office.

The St. Louis Post-Dispatch says the venting should take about 15 minutes, and emergency officials hope to reopen a closed stretch of Lindbergh Blvd by noon today.
