👉 Indicating fumes are odorless gases that can be detected by the human nose, often signaling the presence of hazardous substances in the air. Common examples include sulfuric acid, which has a strong, pungent smell like rotten eggs; hydrogen cyanide, which has a sweet, fruity odor; and chlorine, which emits a sharp, chlorinated scent. These fumes can alert individuals to potential chemical hazards, helping to prevent inhalation of harmful gases and prompting immediate action to ensure safety. Recognizing these indicators is crucial in industrial settings, laboratories, and homes where chemical exposure might occur.
