I’m not going to say no, however my nozzle has been pretty gross for a long time between cleanings and never been an issue.
The bigger danger is that the thermocouple could fail and allow runaway heating (beyond 300c). But most good print firmware is supposed to prevent that.

Not really. Nothing on the printer get hot enough for that.
But there is a large risk of the extruded plastic adhering to it and of it contaminating your print.

Thank you! I’d rather deal with a contaminated print than a fire
