Reply to comment by picklefluffer in TIL that a typical fire extinguisher only lasts seconds while continuously being sprayed. A 20 pound extinguisher can only be sprayed for 25 seconds. by rtpkickballer

Just to ask the question. hypothetically, if the oven had a convection feature turned on, is that fan just moving the air around the ovemn? or introducing outside air? if outside air., I imagine it would just feed a fire in this case. but Im guess, no outside air is introduced to the oven. Perhaps a reddit oven pro can fill me in?

In practical terms, introducing fresh air means that the OvenU needs to heat it (requiring energy). You'd also need a definite exhaust path for the (quite hot) air. For a standalone cooker, that would heat the kitchen in short order. For these two reasons it makes sense that they'd be a closed systen.
