Hold a kick-off safety meeting at the start of course that is mandatory for all students to attend. This will place a large emphasis on the importance of safety and explain all necessary information that must be conveyed for a safe wood shop environment. Do not rely on students to take home safety material and read it for themselves. They often will find this boring, and then you have no way of making sure they know the hazards and how to prevent them.
Explain the rules and consequences as plainly as possible. If students are explained the rules they are to follow and what could happen if they do not, they are far less likely to purposefully try something dangerous.
Walk around the woodworking area or shop with all students and point various hazards or safety concern areas. Identify the names of specific types of machinery used in cabinetmaking and explain what risks the students could undertake when using that equipment.
Show students where all first aid kits and emergency materials are kept. Explain what to do in an emergency and keep a cheat sheet of these steps posted somewhere clearly visible in the shop.
Stick to your rules about safety. If someone is pushing the limits you have set and endangering his or others' safety, take action immediately and set a precedence for what kind of behavior will not be tolerated.
Review what went wrong when a safety emergency does happen. Though it may be too late to turn back the past and reverse what has already been done, students need to understand how to react differently if the situation were to occur again.
