Safety Tips

Please take the following steps to secure your living space and to protect valuables:

  • To prevent unauthorized entry to your living space, lock your door and window whenever you leave your room or are sleeping (even briefly).
    • Pro Tip: Do not leave notes on your door or dry erase board announcing that you are away, or post your daily routine.|
  • Do not put your name and address on key rings (they’re undescriptive for a reason!).
  • Keep valuable items like cash, checks, credit cards, and jewelry locked in a safe place, and consider taking these items with you during extended times away from campus.
    • Pro Tip: Consider acquiring a securable footlocker or trunk, and lock up items when guests and visitors are in your living space.
  • When leaving your room, keep a light on to give the appearance that someone is in the space, and you’ll return to a lit room.
  • Identify high-value items and keep a record, including serial numbers. Register your laptop and bicycle with MIT Police.
  • Residents are strongly encouraged to obtain insurance to protect personal property as MIT assumes no responsibility for lost, stolen or damaged personal items.

Below, please find tips, resources and other fire safety information to help ensure your safety and the safety of your residential community.  Please take a moment to review all of this information carefully as fire emergencies can occur unexpectedly with little or no warning. 

Fire Prevention 

  • There are simple steps you can take to help prevent fires in your living areas, which can be caused by many different things such as overloading an electrical outlet or forgetting to turn off the stove.  Please take a moment to review the fire safety information provided by the MIT Environment Health & Safety Office (EHS), as well as this virtual EHS fire safety training.  When in doubt, always double check whether you’ve left on a burner or forgot to unplug a device.  

If You Encounter a Fire

  • Stay calm and evacuate the area immediately according to the evacuation procedure outlined below. Do not attempt to extinguish a fire unless it is necessary to do so for you to escape. If an alarm is not already sounding, activate the nearest fire alarm pull station as you evacuate or, if this is not possible, yell “Fire” as you depart the building. For additional guidance, please review information on MIT’s Emergency Management website.  In short, evacuate as quickly as possible! 

Evacuation Procedure 

In the unlikely event of a fire, please follow the building evacuation procedure listed below: 

  1. Select the nearest exit
  2. Do not take the elevator
  3. Activate the manual fire alarm if not already sounding
  4. Travel along the right-hand side of corridors and stairwells
  5. If possible, direct yourself to the designated assembly locations* for your building (indoor or outdoor), and away from fire lanes. 
  6. Do not stand in front of the building entrance.  Firefighters require easy access to the building.
  7. If there is inclement weather, take shelter in nearby buildings wherever possible.
  8. Once the Cambridge Fire Department or staff from Housing & Residential Services give the ‘all clear,’ you may return to your room.

*Assembly locations are reported on the Emergency Evacuation Plan posted on each floor next to elevators and stairs.
