When should students enter the lab?

• A. Before the TA arrives
• B. After the TA has arrived and asks them to enter
• C. Anytime
• D. During a break

Answer: (B)

Safety in the lab depends on having supervision and a proper safety check before anyone steps in. The TA arriving and then asking students to enter ensures that PPE is on, the workspace is ready, and any hazards or equipment issues have been identified and addressed. This coordinated entry helps prevent accidents and ensures everyone can work under informed supervision. Entering before the TA arrives bypasses the safety briefing and setup checks; entering at any time or during a break also ignores the required coordination and can expose you to hazards or disrupt ongoing lab preparation.
