The Security Department of Merchandise Mart Properties, Inc. (MMPI) provides 24 hour a day, seven day a week coverage of the interior and exterior of The Merchandise Mart. MMPI security works closely with the Chicago Police and Fire Department providing rapid and reliable response for the building. 

The Merchandise Mart's Security Office, located in Suite 133A on the first floor of The Mart, coordinates all activities and is open 24/7.  After hours there is a secondary Security Command Post located in the South Lobby is manned and serves the same purpose. All security personnel carry two-way communication devices to facilitate communication and response. 

Should it ever be necessary for 911 to be called, it is vital that the Security Office is also notified after they call 911 so the building can take whatever actions are necessary to ensure the safety of the tenants and assist Emergency Services personnel. Examples of our actions may include bringing an elevator to the first floor to facilitate transport of emergency personnel, or dispatching an officer to assist with the situation. In short, the more we know about any emergency in a timely manner, the better we can assist.
