What should you never do in a laboratory?

Eating, drinking, or applying cosmetics while working in a laboratory poses significant health risks and safety hazards. Laboratories often contain hazardous materials, chemicals, and biological agents that can contaminate food or personal care products. Consuming food or drink can lead to accidental ingestion of harmful substances, while applying cosmetics could transfer contaminants from hands or surfaces directly to the face, increasing the chance of exposure to toxic agents. Maintaining a clean and controlled environment is critical in laboratory settings; therefore, these practices are strictly prohibited to ensure the safety and well-being of all personnel.

This understanding helps reinforce the importance of discipline in maintaining health standards in a lab, which can safeguard against accidents and long-term health issues.
