Aerobatic fire fighting
At first I thought it was a video game....
Comments suggest the location is the Border of Spain and Portugal.

Is each cycle he flies over-torquing the transmission?
From my single spin in a Squirrel as a passenger, I remember a horn sounded as the pilot performed a fairly tame quick-stop. He explained that a sensor detected when any stresses above the normal were detected and sounded in good time to allow the pilot to rectify the situation. The horn must have been on a lot during this flight.

From the slow climb, I'd suggest: nope!
As you say, ''my single spin as a passenger'' and sounds like your pilot gave you a BS explanation about the horn.... 
In the tame Q-stop of yours, your pilot managed to get the high NR warning on. With low collective setting a little G-loading (aft cyclic) it will activate easily, unless you know what you're doing... unlike your pilot it seems.
The ''sensor'' (separate system from high and low NR) senses an ''over limit'' generally, N1/Ng overspeed or over-torque. It sounds either before it reaches the t/o transient limit if the inputs are abrupt, or if you've been over transient limit and if it has been high enough and for long enough in which you'll get an ''over limit'' message on your VEMD screen
This is for B3's and VEMD equipped B2's, not applicable for the older models with analog gauges though.
In this video, I can't see the pilot exceeding any limits from the handling, but it is quite sporty manoeuvring for sure. Looks like he has done this more than once or twice before....

Very professional comments from the professionals.
Agree with "sherpa" that it could be a bit smoother.
I personally prefer to fly the bambi short on grass- and bush fires.
Forest fires require longer lines, I agree.
