Also, for anyone who was interested: The firefighting was awesome. Had to go into the unit in full fireproof gear and breathing apparatus. Entire place was filled with smoke and we couldn't see a thing. Had to follow the hose down some stairs and around the mock up pump room, which was about 80 degrees C. Got sorted out, opened the door to the engine room area and crawled inside. It was mental. About 250 degrees C. I'll never complain about being too warm again. Soon as number 1 hit the fire, the entire room filled with steam and got a lot hotter. Stumbled around in the dark, found the casualty and dragged it back up top, and hoisted it out. In total, we were in there about 25 minutes. I was absolutely soaked through with sweat lmao. Was extremely fun though, and I'd definitely do it again! (I have to do the advanced course in about 3 years.)
Edit: And in response to the above discussion, bigger isnt always better
Moderation is certainly best. Yui/Ritsu love <3
