I partially agree with you and I wanted to use the analogy more for the part where he/she only really fights fires a part of the compensated time and is also paid for being "just waiting". I think taking the analogy to far won't work anyway (fires don't happen that frequent actually in less big cities, there's a lot of other stuff they do, compensation IMHO dies not relate to putting your life at risk at all, there's volunteers to which are even paid less, ...). My main point is along the line if your customer wants these nines, they have to do (pay) something. If you as employer want it, same. You as employee are just at "the end of it".
