Absolutely not true. Inhalation of HCI is and should be of immediate concern for anyone in the affected area. The PEL MAX exposure in industrial settings is 5 ppm. Alarms are always set to .5 to .9 ppm. At 5ppm and exposure for a hour or less will be catastrophic effect. There is no way of knowing the concentration level without instrumentation detecting those exposure areas.
