When using strong acids and bases, where should an analyst work?

Working with strong acids and bases requires a controlled environment to ensure safety and minimize exposure to harmful fumes or spills. A fume hood is specifically designed to safely handle hazardous substances. It provides ventilation that directs harmful gases or vapors away from the analyst, protecting them from inhalation and exposure to highly corrosive materials.

In contrast, an open area lacks the necessary containment and ventilation features to protect the user from potential hazards posed by strong acids and bases. A walk-in cooler is not appropriate as it does not provide the necessary ventilation or safety measures, and it could lead to a buildup of dangerous vapors. Using a laboratory sink would not be safe either, as it does not provide a controlled environment for handling these materials, and spills could lead to accidents or contamination.

Therefore, using a fume hood is the safest and most appropriate option when working with strong acids and bases. It safeguards the analyst by ensuring that any hazardous fumes are adequately evacuated, thereby reducing the risk of exposure and maintaining a safe working environment.
