**Typically, a STILL & BOX alarm is requested by a fire officer.   However, there are instances where the Fire Alarm Office can transmit a Still & Box alarm.  These situations typically arise when one or more of the following conditions are met:
- A caller reports someone is trapped in a fire building;
- Multiple structures are reported to be on fire;
- A large commercial type building is reported to be on fire; or
- A building collapse or train derailment

**Also, there are certain situations where procedure indicates that the Fire Alarm Office must automatically transmit a STILL & BOX alarm.  These situations include:

- A report of any type of fire, including an odor of smoke, in a building such as a nursing home, theater, government building, hospital, or other place of public assembly that has a pull box at its disposal (see description of BOX alarms below); and
- A stand-by alert at an airport (plane in distress).

Box Alarm - 4 Engines, 2 Trucks, 1 Battalion
(Alarms received to the Alarm Office from an Alarm Pull Station)

**These box alarms are usually referred to as "cold boxes" and typically do not amount to much of anything.    If a cold box turns out to be a fire, the box is then "filled out", with additional companies assigned to bring the alarm level up to the STILL & BOX alarm level.
