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. Cynthia Runkel Chemical Hygeine Officer
