What is the proper way to smell a chemical?

Wafting the air above the chemical container towards your nose is the safest and most appropriate way to smell a chemical. This technique minimizes the risk of direct exposure to potentially harmful vapors that could be released from the container. By using your hand to gently push the air towards your face, you can assess the odor without exposing yourself to high concentrations of fumes, which is particularly important for hazardous substances.

This method is taught in laboratory safety to ensure that individuals are aware of the risks associated with inhaling chemicals directly from their containers, as doing so can lead to respiratory irritation or other health issues. Always prioritizing safety and using proper techniques for assessing chemical properties is critical in a laboratory environment.
