The exhaust fans are supposed to continue running to pull the smoke out.
I beg to differ with you, electure, about the electrically held contactors. IMHO Shunt trip breakers should be on all the electrical equipment under the hood. Any gas equipment should have valves that shut off as well. I don't like the idea of cooking equipment being dependant on an electrically held contactors. I submit this for your consideration, sir, with the utmost respect.
