The fire alarm rang

Three different fire engine companies (or fire stations) receive the call to go fight that one fire. Usually that means its one really, really big fire. The above is partially correct, but still incorrect. A multi-alarm fire is given its' alarm number (one-alarm, two-alarm, etc) based on the number of "units" and firefighters present at the fire. Here in Kern County, two engine companies may respond, and the fire may still be classified a one-alarm fire. I have dispatched 2 engine companies (7 units, 23 firefighters) to a warehouse fire, that was coded a three-alarm fire. Not every city or county uses this method of multi-alarms. It is however, the most widely used system. Other factors also play into the multi-alarm system. Such as firefighters needing relief from exhaustion, the fire spreading to other buildings/structures, or the fire simply being to big to contain with the resources available at the fires' location. These will almost always result in more engine companies being called in to assist, thus raising the multi-alarm code to the next level, or higher.
