COLUMBIA — A laboratory in Lafferre Hall at MU where a glass container of hazardous materials ruptured around 8 p.m. Wednesday was cleaned, inspected and released to the lab's researcher Thursday morning, MU spokesperson, Christian Basi, said.
The situation was turned over to the MU Environmental Health and Safety Department.
Wearing protective clothing and respirators, the Health and Safety Department investigators identified several chemicals involved in the spill, which amounted to about one-half gallon of materials. Several common cleaning compounds (methanol, acetone and isopropyl alcohol) were found, in addition to potassium hydroxide, aluminum and copper sulfate, Basi said. Mixtures of some acids were also present, but the Health and Safety Department is still working to identify them.
"This is very, very rare," Basi said. The Health and Safety Department is now investigating the cause of the spill, which Basi said is still unclear.
No injuries were reported as a result of the spill, which was discovered and reported by Dan Howard, a research assistant in the building at the time.
Firefighters donned protective clothing and air packs in order to enter the laboratory Wednesday night. They examined the extent of the spill and tested the oxygen level in the room, according to a news release from the Columbia Fire Department.
"The important thing," Basi said, "is that the response of the individual who found the spill and the response of the team that responded to the call, including the fire department, MU Police Department and the Environmental Health and Safety Department, were excellent."
