I am not sure about the reason for a heat/ smoke detector to cover an oil filled transformer. The oil is normally a non combustible (under definition of NFPA) product and transformers under many circumstances blow up at which point smoke detectors would be meaningless. I have never seen a transformer fire but I have seen them blow up.SUBCHAPTER F: ABOVEGROUND STORAGE TANKS (8) a tank located on or above the surface of the floor of an underground area, such as a basement, cellar, mineworking, drift, shaft, or tunnel, if the sole or principal substance in the tank is a hazardous substance; and (9) a tank that is located at or is part of a petrochemical plant, aFIST 3-30 TRANSFORMER MAINTENANCEAcronyms and Abbreviations A air ANA self-cooled, nonventilated kW kilowatt ANSI American National Standards IEEE Institute of Electrical and Institute Electronic Engineers CEGB Central Electric Generating M/DW moisture by dry weight Board mg milligram cfm cubic feet per minute mva mega-volt-amps CH 4 methane ND not detected C 2 H 2 acetylene N 2 nitrogen
Apr 25, 2019 · Matthew Pilgrim Senior Consultant Engineer (FM Global). Carl, in general transformer bunding is a good idea, but can be a costly exercise for existing installations. Factors to consider are: the cost and lead time of the transformer, its impact on production, whether an oil fire would expose adjacent transformers or buildings and the type of oil used (mineral oil, natural or synthetic esters).Nitrogen: A Security Blanket for the Chemical Industryvapor space of a storage tank or process vessel, making it inert. This eliminates the possibility of fire or explosion, decreases evaporation, and protects the tank from struc-tural corrosion damage caused by air and moisture. It also prevents air, moisture, or other contaminants from enter-ing the vapor space and causing product degradation.
