Rescue5271 - MFS pumps are not allowed to respond to jobs with three people on board, if a firey is sick or unable to work then they will recall another person and take that truck offline until they have a full compliment. A couple of fireys are rostered on each shift to fill in the gaps and ensure they have a full compliment.
If there are trucks getting around with three on board I think the Union would hit the roof, maybe you saw one of the training trucks getting around at the moment with the new recruits.
Depends on the appliance... there are 4 per crew on pumps and the heavy rescue... 2 on HAZMAT/BA and aerial, not sure but i think that the skyjets are 4 per crew.... 2 per ROSA?
Medevac, the ROSA normally responds with one, if it's the CBR truck from HQ it normally goes with just the on-call CBR officer. The ROSA at Largs North is driven by the Marine Officer. Skyjets are crewed with four.
