Lane's story, while incredibly rare, isn't unique. A 2002 report from Center for Disease Control on hand hygiene in hospitals describes one incident in which a health care worker ignited the vapor from hand sanitizer with the static electricity she created from removing a gown and then touching a metal door. In 2006, a similar incident occurred, when a nurse's hand--wet with sanitizer--caught fire as she changed a dial in an oxygen-enriched environment. A spark of static electricity can set hand sanitizer ablaze, but it's extremely uncommon. "[The Lane case] was an outlier as far as I can tell," says Mark Bruley, of ECRI Institute, non-profit focused on improving health care safety.
