How do you deal with safety in the classroom?

The way that I plan to keep my classroom a safe place is by keeping the students informed. By informed I mean that I will make students aware of the materials they are using as well as the rules. Some materials are dangerous if they are not used properly so I think it is highly important to have a demonstration. At the beginning of the class it is also important to show students safety hazards there might be with in the classroom. I think it is also not a bad idea to remind students of these safety measures as you go incase they may have forgotten.
