• Resumen

  • A scenario based on actual cases is presented in which a consumer fails to detect a gas leak. A spark source ignites the vapor, causing an explosion and fire. Odorant added to alert people of gas leaks is not always detected for a number of reasons, including nasal congestion, sleep, odor fade, masking, and adaptation or habituation. Electronic gas sensors that alarm in the presence of explosive gas are available in the consumer marketplace and could augment leak detection.
