What is the primary purpose of a chemical fume hood?

The primary purpose of a chemical fume hood is to exhaust chemical vapors. Fume hoods are critical components in laboratory safety, designed to protect users from exposure to hazardous fumes, vapors, and dust that may be generated during chemical processes. By effectively ventilating these potentially harmful substances outside of the laboratory, fume hoods help maintain a safe working environment and reduce the risk of inhalation or contact with toxic agents.

While providing light to a workspace, storing chemicals, and cooling samples are important factors in laboratory operations, they do not encompass the primary function of a fume hood. The essential role of these hoods is safety and ventilation, making them vital in environments where hazardous chemicals are handled.
