- wear safety goggles — Yes. NaOH is corrosive and can severely injure the eyes.
- have his water bottle on the lab desk in case he gets thirsty — No. Food and drinks are not allowed in the lab to avoid contamination and accidental ingestion.
- wear a lab coat — Yes. A lab coat protects skin and clothing from splashes.
- read any safety information, such as the SDS before he begins the experiment — Yes. The SDS gives hazard information and first‑aid, PPE, and handling instructions.
Additional recommended precautions: wear chemical‑resistant gloves (e.g., nitrile), closed‑toe shoes, keep eyewash/safety shower accessible, and know spill/neutralization procedures.
