About the hoses, you need to have a valve to allow more than one hose connection. You can't just connect it from the truck. In order for the water to work, it has to be connected to a valve. Firefighters coughing, they need to have SCBA. If they're too close without SCBA, than they'll cough. Just move them farther back though if they don't have SCBA. Missions: I also got jumper, tree blocking road, and one where there was a tree on top of a man (physical rescue assignment).
