Should you eat in a lab setting?

• A. Yes, you may eat as long as you wear gloves.
• B. No. you should also avoid applying makeup.
• C. Yes, but only near the sink.
• D. No, but makeup is allowed.

Answer: (B)

In lab safety, the priority is preventing any ingestion or transfer of hazardous substances. Eating in a lab creates a direct path for chemicals to enter your body and can contaminate work surfaces and samples. Wearing gloves does not make eating safe because you can still transfer substances from contaminated food to your mouth or eyes. Makeup is discouraged for the same reason: cosmetics can trap residues and be carried to your face, hands, or equipment, increasing exposure and risking contamination. The safest rule is no eating in the lab and no applying makeup, with meals and cosmetics kept in designated break areas away from work spaces. Always wash your hands before leaving or re-entering the lab.
