Subject: Explosive proof hot plate in a hood?

Interesting Question:

I am working on an issue about a "so-called' requirement for an explosive proof
hot plate installed in a hood.  The flammables used in the hood are no
different than any I have seen anywhere, in other words, they do not use large
volumes or extremely flammable solvents.  What I cannot wrap my head around is
that my understanding of the use of explosive proof equipment is for ambient
explosive atmospheres.  Why should a hood with ventilation have an explosive
proof hot plate requirement?

I appreciate any feedback or fire codes which would make this a requirement.
