No. closest thing to a RAC unit would be 5 Highrise and 7 Airlight. FRP's run X-Airdrie ambulances but they are not allowed to transport people to hospitals, though they are literally set up like ambulances. I don't know of any other departments that have firefighter/medical programs quite like this, so i have nothing to compare them too.
For Haztec's, I dont know much.. they run separate from the bigger Hazmat trucks - those 3 trucks in the city respond to any sort of hazmat situation - spills, CO alarms, etc... and should have a haztech level trained crew on board, just like the 4 Hazmat Engines in the city. The Haztech vans I would think run a higher ranking firefighter, one that could take charge of the technical stuff at a hazmat call but not like a district chief/battalion chief level firefighter.
Please someone correct me if i'm wrong!
