What is the rule regarding the use of tools with circular rotating blades?

• A. They can be used when a safety guard is in place.
• B. They may not be used without the presence of the Technical Director.
• C. They can be used by anyone with a helper.
• D. They can be used during lunch breaks.

Answer: (B)

Rotating-blade tools demand supervised use by a qualified overseer. The rule requires the Technical Director to be present before these tools can be used, because their role is to verify proper setup, ensure guards and PPE are in place, and confirm the operator is trained and aware of emergency procedures. This supervision acts as the safeguard beyond the guard itself, preventing unsafe practices and addressing any issues before operation begins. Guards help reduce risk, but they don’t replace the need for a trained supervisor, and options about using the tool with a helper or during breaks would skip the essential guidance and checks that keep students safe.
