In the case of a free-breathing transformer, the oil may become satu-rated with air. Even in this latter case, where the maximum amount of oxygen (about 30,000 parts per million) may be present in the oil, it is fully dissolved. Consequently, in both cases, there is no “free” oxygen available to support a fire inside the transformer.
