NOTES:

Rescue 1 can be assigned as needed.

If a unit is sent on a Signal 5, they cannot request a Signal 10, as no box was assigned. They must request a full assignment to be transmitted.

Only a chief officer can order a Signal 309 or a Signal 11.

Once a Signal 11 is transmitted, it cannot be downgraded.

A Signal 11 does not necessarily indicate a working fire. It means that a full first alarm assignment is working at a particular incident. In the past, a Signal 11 has been sounded for auto accidents, smoke investigations, haz-mat situations, etc.

A Second Alarm can be ordered by the officer of any company, but subsequent alarms must be ordered by a chief officer, or with his authorization.
