Correct actions:
- Tell your teacher right away. — Yes. Get help/medical attention and follow lab emergency procedures.
- Rinse the exposed skin with water. — Yes. Immediately flush the area with copious running water for at least 15 minutes; remove contaminated clothing/jewelry while rinsing.

Do NOT do these:
- Try to save the NaOH for recycling purposes. — No. Don’t handle/collect used chemical after an incident; leave cleanup to the teacher or trained staff.
- Neutralize by applying a small amount of acid (e.g., HCl). — No. Adding acid can cause an exothermic reaction and more tissue damage.
- Wipe the NaOH with a paper towel and continue the experiment. — No. Wiping can spread the chemical and does not properly decontaminate the skin.

If symptoms (burning, blistering, numbness) persist after rinsing, get medical attention.
