Danger!
Suffocation can occur in a nitrogen-atmosphere oven chamber if
it is not thoroughly purged with room air before a person goes
inside it.
Before entering an oven chamber, run the oven for at least five
minutes with the nitrogen (or any other inert gas) turned off,
doors open and recirculation fan running.
Do not work inside oven with the doors closed if you have not
purged the chamber with nitrogen (or any other inert gas) first.
