wash hands turn off all equipment put away all glassware wash instruments and table tops
I gave my students this multiple choice question: A student has just completed a laboratory activity. What is the last action that the student should perform before leaving the lab area?

Only one answer is correct among these 4 choices:
- wash hands
- turn off all equipment
- put away all glassware
- wash instruments and table tops

Could you tell me which one is correct?
