If your question regarding fire zone is related to a system that follows API 521, then also review the section in API 521 covering "Vapor From Fire Heat Input". That's section 3.19.2.2 in my 4th edition, I believe the section number but not the title has changed in the more recent 5th edition. The dicussion indicates considering a fire zone to include 2,500 ft2 (232 m2) of plot area but you should read the full discussion.
