To safely detect the odor of a chemical, the wafting technique is employed, a method that reduces your exposure to potentially harmful substances. The wafting technique is a method used by laboratory professionals to safely detect the smell of a chemical without directly inhaling it. Instead of placing your nose near the container, which could expose you to toxic or concentrated vapors, you use your hand to gently fan the vapors towards your nose. Prepare Yourself: Before beginning, ensure you are wearing the appropriate personal protective equipment (PPE). Work in a Well-Ventilated Area: Always conduct wafting in a well-ventilated area or fume hood to avoid inhaling large quantities of vapor. Position Yourself Safely: Stand slightly back from the container of the chemical. Waft the Vapors: Hold the container at a safe distance, approximately arm's length away. Using your free hand, gently wave the vapors toward your nose by moving your hand in a slow, sweeping motion. Take Short, Gentle Sniffs: When wafting, take short and gentle sniffs rather than a deep inhalation.
