Your job is to teach and to keep everyone in your room safe.
You have to be present every moment you are in the classroom and every moment you are around the students in other spaces. You have to be aware of each student in your space - how they are feeling that day, what their habits are, who they do not get along with, what they are capable of.
You need to start recognizing the little things that will become larger problems. Prevention is a lot easier than reaction and punishment.
You must also work hard to build positive habits through purposeful routines - routines help students to behave in expected ways because their is no guesswork and the patterns are easy to follow.
Students crave structure. They need structure. You are the one that needs to provide it. Your team needs to work together to set clear expectations.
