A chemical spill at a University research building led to a brief evacuation Friday.

Around 12:55 p.m., the Masonic Cancer Research Building located on 425 E. River Parkway was evacuated for precautionary reasons due to a chemical spill, said a University spokesperson.

Minneapolis Fire Department responded to the incident, the spokesperson said.

A “very small pipette of fluid” was mishandled, causing the spill, said Bryan Tyner, public information officer for the MFD.

An alert announcing the building was clear and safe to return to was sent at 1:45 p.m. Personnel were let back into the building after the fire department deemed the air to be non-hazardous, Tyner said.
