Nitrous oxide, with the chemical formula N₂O, also known as "laughing gas," is a commonly used chemical in chip manufacturing. At room temperature, it is a colorless, non-flammable gas with a slightly sweet odor and mild anesthetic effects, capable of inducing laughter, hence its frequent use in the medical field as an anesthetic to alleviate pain. 1 However, while this gas is not harmful to the human body under normal circumstances, it requires careful handling. Although non-flammable itself, it is an oxidizer and supports combustion. 1 If nitrous oxide stored in steel cylinders is exposed to flames or heat and its pressure relief device fails, it can potentially lead to a cylinder explosion, posing a safety hazard. Therefore, when using and handling nitrous oxide, it is essential to strictly adhere to safety operating procedures to ensure a safe and stable working environment.
