Thank you, I have done that many times, the last job I had, they had just moved the mircowave to lower floor with the popcorn.  Employees were not happy with it and with it even being taken to another floor, it still affected me through the air ducts.  I had to go to the emergency room twice and missed alot of work due to the reactions.  I don't know why people have to have microwave popcorn in the work place anyway.
