would you call out your brigade Pip?
Depends on what the hazard is, where it is, and what sort of a risk it poses.
We tend to get called out more for traffic control (usually a 20 + minute delay for a police patrol to attend in our area), and with the multitude of blind corners, and morons that hoon around the hills, particularly at night) my primary concern is safety of those at the scene...
I've come across hazards on the road, which I have simply stopped and removed it myself, rather than call out CFS - or contacted the Council or DRT to deal with - but it all depends on the circumstances.
I am happy to call out my brigade to assist when it is something that poses an immediate hazard and deal with....we have been called by the local tow truck operator, to do traffic control, on a blind corner, while he dragged a car back onto the road. (Police didn't attend).
