    • Exposure Limits:

      NIOSH REL*: TWA 25 ppm (46 mg/m 3 ) (TWA over the time exposed) [*Note: REL for exposure to waste anesthetic gas.] OSHA PEL : none NIOSH QX1350000
    • Chemical Class:

      A nitrogen oxide consisting of linear unsymmetrical molecules with formula N<smallsub>2</smallsub>O. While it is the most used gaseous anaesthetic in the world, its major commercial use, due to its so lubility under pressure in vegetable fats combined with its non-toxicity in low concentrations, is as an aerosol spray propellant and aerating agent for canisters of 'whipped' cream.
