What is the significance of ensuring good ventilation in the lab?

Ensuring good ventilation in the laboratory is crucial primarily because it reduces the accumulation of harmful fumes and vapors. Many chemicals used in organic chemistry can release toxic gases or vapors that, when inhaled, can pose serious health risks including respiratory issues, dizziness, or long-term health effects. Adequate ventilation facilitates the dispersal of these potentially harmful substances, keeping the air quality safer for everyone working in the lab.

Additionally, while better lighting, temperature control, and space for movement are important, they do not directly address the critical safety concern of airborne contaminants. Therefore, proper ventilation is fundamentally tied to maintaining a safe working environment in any laboratory setting.
