“We have activated our emergency response plan. That is a structure that allows us to make sure we have adequate staff and other resources and procedures in place to respond to an event such as this,” Burns said. “We practice this with local law enforcement and first responders on a regular basis. … Because of that and because we take this very seriously, we’ve been able to respond very well to this large-scale event in Springfield.”
Authorities did not release a cause for the suspected carbon monoxide problem.
