February 25, 2022 the Bulletin of Atomic Scientists published an article quoting Robert Pope of the DTRA's Cooperative Threat Reduction Program
Direct Quotes, Robert Pope:
“I would say from every facility that we have worked with them in, we have confidence that as long as the electrical power is turned on and the people we have trained are present at the facility, the biosafety officers, that these pathogens are safe and secure to international standards,” Pope said. “Should these facilities be damaged by conflict, that could change.”
The pathogens with which the Cooperative Threat Reduction Program labs work are generally kept frozen, so they can’t replicate and become infectious. The risk the pathogens pose would increase if a building lost power and suffered damage. “If you lose the electrical power, the pathogens in the freezers warm up,” he said. “If the ventilation system is damaged, or the building itself is damaged, and these now ambient-temperature pathogens are able to escape the facility, then they can be potentially infectious in the region around the facility.”
