Weapons and Dangerous Objects

MIT prohibits in any building, space, or grounds used for Institute purposes, including in any residence hall or FSILG, or in any motor vehicle on property or vehicles used for Institute purposes, all weapons and other objects that can be used to cause physical harm, that can be used to threaten physical harm, or that, by their appearance, could reasonably be perceived as weapons or objects that could be used to cause physical harm (e.g., replica firearms). 

Illustrative examples of prohibited objects include but are not limited to:

  • shotguns, rifles, pistols, revolvers, and other firearms (including ammunition)
  • hunting knives, switchblades, swords, and other dangerous blades
  • air rifles/pistols, air-soft rifles/pistols, and b.b. guns (including ammunition)
  • bows, crossbows, and arrows
  • tasers, martial arts-type weapons, mace or pepper spray, and explosive or flammable materials (including recreational fireworks)

To read the Institute's full policy on weapons and dangerous objects, please see the Mind and Hand Book. Questions concering whether a particular object is covered by this policy, or cases for exception, may be submitted to the Chief of MIT Police or his or her designee, whose determination shall be final.
