Multiple gas explosions in a one block radius causing the entire block to be involved...thats all I can think of...or maybe a huge warehouse, which would be just as big. 5th alarm assignments are very rare. On 9/11/2001 The highest the alarms got was 5 alarms for each tower. (I guess you technically could make that a 10 alarm assignment)

It's called a PASS (Personal Alert Safety System) device that can be found on the SCOTT Air packs. The pass devices are activated when a firefighter transmits a mayday and activates his PASS device or stops moving for more than 30 seconds. It would be a nice feature but are quite annoying because they go off until someone deactivates the device which means if you dont have EMS on the scene in game these annoying alarms will be going off. If you do add them then make sure you make it a low volume because even in real life these things are really annoying. Every thirty seconds you have to move your airpack to make sure the alarm doesn't go off and when I was in my local fire academy class every time we let a PASS device go off we had to do pushups.
