Sheltering In-Place



In specific instances, an evacuation or moving to a civilian shelter or designated place is more dangerous than remaining where you are, such as with short- or no-notice emergencies, including hazardous materials events. In these instances, you may be directed to shelter-in-place. Sheltering-in-place means to take temporary protection in a structure or vehicle.

Installation procedures designate which responsible party or office will order personnel to shelter-in-place and for how long the order is expected to be in effect. Each instal­lation is responsible for developing Shelter-in-Place Management Teams in designated high-risk or high-occupancy buildings or areas. You should plan ahead by having an emergency supply kit with needed food and supplies in the locations you spend most of your time.



How to prepare

  • Verify and update official contact information in the Marine Corps Enterprise Mass Notification System (eMNS), and register all cell phones, home phone, email addresses, etc. in eMNS. 

  • Know how to turn off your heating, ventilation, and air conditioning (HVAC) systems without damaging the components.

  • Know how to close and secure doors, windows, vents, and other exterior openings quickly.

  • Identify potential interior space for sheltering-in-place.

  • Make an emergency plan.

  • Build an emergency kit.



How you will be notified

  • Giant Voice (GV)—A voice an­nouncing system using exterior speakers, commonly termed “Giant Voice”

  • Interior Voice (IV)—Interior speakers or sirens within individual buildings

  • Enterprise Mass Notification System (eMNS)—An interactive, com­munity notification system capable of providing voice and/or data messag­es to multiple, designated receivers

NOTE: You must register your personal information in eMNS to receive notices after hours and away from the office on personal devices.



If in a car

  • Close windows, vents, and HVAC 

  • Drive away from visible gas/cloud

  • Tune into Emergency Alert System or radio

  • Wait for all-clear

  • Muster



If ordered to shelter-in-place

  • Bring everyone safely inside to an interior room or one with as few windows and doors as possible.

  • Turn off all HVAC systems.

  • Close and secure all doors, win­dows, vents, and other exterior openings.

  • Have an emergency supply kit ac­cessible.

  • Listen to the radio or television for further instructions.

  • When the “all clear” is announced, open windows and doors, turn on ventilation systems, and go outside until the building’s air has been exchanged with the outside air.

  • Once you are in a safe place, follow your command’s protocols for personnel accountability and contact your command’s designated Point of Contact to check-in and report your location and situation.
