30-475: A "first alarm" and is typically the largest. Subsequent alarms are calls for additional units, usually because the fire has grown and additional resources are needed to combat it, or because the incident is persisting long enough that firefighters on scene need to be relieved. Requests for units and firefighters from outside jurisdictions do not normally occur in multi-firehouse urban areas until elevated alarms are reached (alarm three and above), but will depend on

45-512: Is a stub . You can help Misplaced Pages by expanding it . Multiple-alarm fire One-alarm fires , two-alarm fires , three-alarm fires , etc., are categories classifying the seriousness of fires , commonly used in the United States and in Canada , particularly indicating the level of response by local authorities. The term multiple-alarm is a quick way of indicating that a fire is severe and

60-412: Is a basic example of how alarm levels are categorized in a fire department, how many fire apparatus or fire units respond to each alarm level, etc. In New York, however, additional special alarm levels are utilized, aside from the conventional first alarm fire, second alarm fire, third alarm fire, etc. Examples of such alarm levels are the signal 10-75 assignment, the signals 10-76 and 10-77 assignments, and

The most widely used formula for multi-alarm designation is based on the number of units, (for example firetrucks , tankers, rescue vehicles and command vehicles) and firefighters responding to a fire; the more vehicles and firefighters responding, the higher the alarm designation. In terms of understanding

90-560: Is in an addition on each alarm (a five alarm fire assignment has 21 engine companies total). Each total is the total number of units on scene. If the incident commander decides that the incident does not require a higher alarm level to be requested, they can specially request an additional unit to the scene without requesting a full alarm level assignment. For example, at a working fire, there are four engine companies, three ladder companies, one squad company, one rescue company, two battalion chief units, and one division chief unit operating at

Some companies, however, are quartered together at the same firehouse. So, it is not a matter of how many firehouses respond to a fire as popularly believed, but rather how many companies/units and how many firefighters are operating on scene. The system of classification comes from

135-496: The location of the incident and the condition of the authority having jurisdiction at the time of the incident. A common misconception is that a "three-alarm fire", for example, means that three firehouses responded to the fire. This is not the rule behind the naming convention, although some cities may use the number of firehouses responding for multi-alarm designations because that is the simplest way to determine an alarm number. (one operating as FAST ) (one as FAST) The list

150-464: The old tradition of using pull stations to alert the local departments to a fire in their area. When initially pulled, a pull box will pulse its identification number multiple times to a receiving reel-to-reel telegraph unit (typically located in the nearest dispatch office). Within the pull box, a firefighter is able to (via a built-in telegraph key) manually key back to dispatch, including requests for mutual aid. One such code commonly used throughout
