I gave my students this multiple choice question: When there is an accidental spill in the lab, it is most important to know

Only one answer is correct among these 4 choices:
- where the safety goggles are stored.
- what number to call for poison control.
- where the fire extinguisher is located.
- which materials are safe to use for cleaning.

Could you tell me which one is correct?
