I'm still new to IRC, but I never had a problem with anything personally. I have seen some drama/conflict go down, but that seemed to be due to people being too rash.
So, my suggestion (which is probably the easiest to implement) is if someone (staff) is/gets "triggered" by something, they should take some deep breathes and think/rethink about the situation with a level head, and try to act on logic rather than emotion.
I also agree with Etzimal about kicks/joke kicks, I don't really know what kind of image the channel is trying to represent, but it seems more like a place to hang out and talk rather than a professional work environment. There's no harm in a little fun, right?
Lastly, if you're having a bad day, look at some cat pictures/videos or something. http://i.imgur.com/NecOqzl.jpg
