===Emergency===

Emergency transporters are a special type that can only beam someone ''from'' a ship or space station, not the other way around. Emergency transporters have a low power requirement; in case of a shipwide power failure, the crew could use these transporters for emergency evacuation. (TNG Technical Manual)

:''In older technical manuals and other non-canon background materials, these are sometimes referred to as "evacuation" transporters or "combat" transporters.  Typically, they are said to be platforms with a dozen or more pads each.  In addition to emergency evacuation, they are used in ''any'' high-volume movement of personnel, such as in troop deployment.''

By the late 24th century, emergency transport was further improved through development of a single-person, single-use, one-way emergency transport unit.  The device was small enough to be hand-held and could transport to specified coordinates with a single touch.  

Because of its extreme limitations, this device was not widely deployed and was still considered a prototype in 2379. (Star Trek: Nemesis)
