Los Alamos National Laboratory personnel and Los Alamos Fire Department responded to a report of a bulging drum at 2:30 p.m. Monday at the Sigma facility, according to a LANL spokesman.

“The drum has been rendered safe, and there is no threat to workers or the public. Full access to the facility has been restored,” the spokesman said.

The Sigma complex was built in the 1950s and 1960s and houses extensive laboratory areas for materials synthesis and processing, characterization, and fabrication. It supports a collection of tools for characterizing materials, including mechanical testing, hardness testing, electron microscopy, optical metallography, ceramography, differential thermal analysis, thermogravimetric analysis, bulk density, surface area analyses, x-ray diffraction, and powder characterization capabilities.
