COSO's from October 2006 are out of date...the lastest COSO is October 2007.
Each brigade should have been sent a new updated copy, along with new "Operations Management Guidelines" dated Sept 2007
COSO 8, Emergency Response Driving, details circumstances when priority one driving should be used, procedures for approaching Stop signs & traffic signals, railway / tramways crossing, safety & speed limits, school crossing & Road works.
It also details when flashing lights should be used (which includes when driving Priority one)
There is also a mention of use of red & blue flashing lights on private vehicles (not allowed) and a mention of Priority Two driving.
There is also COSO 7, which details driving CFS vehicles (not emergency driving) and talks about wearing seatbelts, training, licensing, vehicle logs, purchase of fuel, reversing, use of mobile phones and towing.
I'd suggest that anyone who drives a CFS appliance, and any one who is likely to be an OIC of an appliance should be familiar with both of these COSO's
