| Resumen |
Shelter-in-place strategies such as remaining indoors; breathing through a damp cloth; sealing cracks in windows and doors using towels, duct tape, or plastic sheeting; and running a shower are often recommended by emergency response officials to protect against the release of airborne hazardous substances such as ammonia. This study was designed to evaluate sheltering-in-place inside a chamber simulating a typical bathroom, using a mannequin. Ammonia gas at 300 and 1000ppm was added to the chamber until the measured concentration peaked and stabilized, then the shower was turned on and the ammonia gas concentration was continuously monitored. Using a damp cloth reduced exposure of the mannequin to ammonia gas by 2 to 18-fold. Turning on the shower was even more effective at reducing ammonia levels. After 27 min, the ammonia concentration in the chamber was reduced to 2% of the initial concentration, even though gas was being continuously added to the chamber. |
