Hi,
I am a volunteer in Kanton Aargau, so I can’t speak for Ticino.
How it works here:
-To join, it was a simple interview with some questionnaire. For the general service, no special fitness requirements (except if you tick some boxes on the questionnaire, they will assume you are fit, otherwise they can send you to a doctor.
-mandatory planned training according to your function. So you have general service for everyone, than the guys who can wear respiratory protection (to go into the smokey buildings - I am doing that), the pioneer group for accidents, machinists to drive the trucks, electricians etc. According to the group you have different trainings. For me it is 4 trainings for the general service (common for everyone), + 8 trainings for the respiratory mask. Normally, you have 3-4 dates per training so you can accomodate easily with your private plans.
-For joining the respiratory mask group, I had a special fitness test and checkup with a doctor. Nothing crazy, just had to to 3 or 3.5 W/kg on a indoor trainer and a quick checkup. Cool thing: you get your HR zones for cycling for free including a mini training plan if you want to improve. Every year we do some fitness parcours in full gear (nothing crazy again).
-I get alarms via phone (call and SMS, stating what it is and where). You just jump and go, no time to think (really cool in meetings which are boring). In our case, we assemble in the barracks, change there and go. Some towns, they have their stuff at home and come equipped directly to the place (must be a shit for parking).You say when you have holidays, but of course they understand that sometimes, it is not possible for you (you are drinking with friends etc.). Basically they expect that if you are in the vicinity sober, and not professionaly bound you come. In my case, my workplace encourages to go and pays the time in service as normal salary (on top of the compensation we get for the service, see below).
For normal people who do not have an officer role, the financial reward (next to having actually a fun sexy job) is quite interesting:
-20 CHF(or was it 25)/h for the trainings (mostly in the evening for 2h sessions)
-50 CHF/h for alarms for each started hour. An alarm with a real fire is easily several hours
-a compensation per day for special trainings (I had 2 days of “introduction training” when I started, plus a one day introduction training for the respiratory mask). I think it is about 250 CHF/d, can’t remember.
-you don’t pay firefighter tax in Aargau (300 CHF/y maximum)
All these figures are net, no AHV and taxes. (for officer roles they get some Pauschale per year, after some limit it gets taxed, but this is not in my scope). In general, I am between 2000-3000 CHF extra net income, since I am in the position to be able to go to a lot of alarms (employer in the same town, no issue with him going). Real stuff is about 5 times a year, mostly it is false alarms.
So basically you get a new hobby, you get paid for it, trainings are fun and you learn a bunch of new stuff. Also, a lot of new contacts, private and professional, since everyone is coming from different backgrounds.
