Officials from the Colorado Rockies and a federal cybersecurity agency are planning a “full-scale” active shooter and bombing simulation at Coors Field to practice responding to an attack during a regular season baseball game.

The May 22 event will bring together stadium and team officials, local first responders and state and federal agencies “to perform response actions that would be taken during an attack at Coors Field,” organizers wrote in an email sent to a Colorado Division of Homeland Security and Emergency Management mailing list on Friday.

Organizers are looking for volunteer actors to participate in the simulation, which will take place when the Rockies are scheduled to play in Oakland, according to the email.

“The scenario involves a simulated explosion followed by an active shooter during a regular season weekend Colorado Rockies game at Coors Field,” organizers with the federal Cybersecurity and Infrastructure Security Agency wrote on an intake form for volunteer actors.

Two 60-minute scenarios will be held during the six-hour training and will include being “exposed to loud noises, including simulated gunshot and explosive sounds,” organizers wrote.

Volunteers are required to be 18 years or older and must answer if they are willing to have simulated injuries painted on or applied, including fake bruises, scratches, burns, gunshot wounds and blood, according to the intake form.

Getting fake injuries applied, which is known as moulage, is not mandatory for participation.

In a statement, Rockies officials said the federal agency was helping design the “closed exercise to evaluate existing protocols at Coors Field, as the safety and security of our fans remains our top priority.”

The Colorado Division of Homeland Security and Emergency Management referred questions about the event to the Cybersecurity and Infrastructure Security Agency. Representatives for the agency could not be immediately reached for comment Tuesday.
