Surgical site fire during surgery in operating room under general anaesthesia

On careful examination, it was observed that the alcohol solution had seeped into the hair of the patient around the right ear under the drapes. [2] The point to consider is that in head and neck surgeries, when alcohol-based preparation is used, it can trickle down into the hair of the patient and may take time to evaporate. [...]only as much quantity of alcohol as required should be used and secondly, draping should be done only when residual alcohol vapours get evaporated beneath the hair (especially long hair of female patients).
