ATR systems - Fire protection

What is the worst thing that can happen to an aircraft? The landing gear won’t come down? Engine failure? Loss of airspeed indication? No. We can manage that. The worst that can happen, is a fire inside the aircraft.
Corrections to the video:
1) The extinguishing agent in the waste bin is not Halon, but Freon.
2) In new ATR aircraft, the Halon in the extinguishers is replaced with Halotron.
3) At 10:50, I said that the pilots cannot know whether AFT SMK is triggered by the detector in the aft cargo compartment or the lavatory. This is correct for variants with EFIS cockpit. In the glass cockpit, the CABIN page will show which detector is triggered.
