Sheltering-in-place is recommended when being outside poses a threat, either from a violent act or a concern about air quality. The decision to shelter in place may be your own, or it may come from MIT or another authority. In either case, here are some tips in the event you have to remain where you are:

  • Find out where the pre-determined shelter-in-place area is for your building. If there isn’t one, remain in your room with your door locked.
  • Check with the MIT information line (617-253-SNOW) for information, updates and recommendations, as well as the MIT emergency website, TV, and radio;
  • Keep windows and window blinds shut. If advised, also cover and duct tape air vents, and turn off all the air handling equipment (heating, ventilation, and/or air conditioning) that you can control.

At 10:45 am, Cambridge Police issued an all clear. MIT has returned to normal operations. MIT Police will continue to monitor the campus.

Cambridge Police have asked students and staff to report suspicious activity to the campus police dispatch on 617 253 1212 or dial 100 from a campus phone.
