The University of Colorado Boulder is set to install locking devices in 39 large classrooms and auditoriums to bolster security during life-threatening emergencies, such as an active shooter situation. The initiative, which will begin this spring, is funded by $3.4 million in state-controlled maintenance funding, alongside technical support from the U.S. Department of Justice. These devices feature a plastic cover with a blue backing and a red button; when activated, they lock classroom doors, allowing those inside to exit while preventing entry by anyone except emergency personnel. This proactive measure is part of a broader campus safety strategy identified during a security assessment, which highlighted large classrooms as priority areas for enhanced security. Training for faculty and staff on the use of these devices is currently being conducted, ensuring readiness in case of an emergency. Eric Jergenson, assistant vice chancellor for Security Services, emphasized the importance of this addition in responding to threats quickly and effectively.
