The Kenner Police Department is warning residents not to be alarmed Saturday at the sound of simulated gunfire, explosions, sirens, fire alarms and screaming that they may hear around John James Audubon Elementary School.

The noises will be part of an exercise meant to test the department and other agencies on their response to “armed intruder” events and similar emergencies, Kenner Police Department Chief Michael Glaser said in a letter to residents on Monday.

West Loyola Drive between Loyola Drive and Notre Dame Place will be closed to traffic from 9 a.m. to 1 p.m. while the exercise takes place. Officials will allow residents to leave and come back to their homes, though anyone returning is asked to use Notre Dame Place.

Glaser said the exercise will not interrupt regular police service.

Kenner Police Lt. Brian McGregor said the media will not have access to the exercise beyond filming from preapproved spots on the exterior of Audubon Elementary given “the sensitivity of the tactics and identity of some responders.”

Besides Kenner police, the city’s Fire Department and Office of Emergency Management will participate.

Other participating agencies from the surrounding area will include East Jefferson General Hospital’s Emergency Medical Services; the Governor’s Office of Homeland Security and Emergency Preparedness; the Harahan Police Department; the Jefferson Parish Department of Emergency Management, public school system and Sheriff’s Office; the State Police; and the St. Charles Parish Sheriff’s Office.
