Quick Plume Data

Quick Plume is an optional service. Contact your sales representative for more details.

Quick Plume creates and displays a dispersion plume that estimates the area that may be affected by a chemical spill over the next hour. Quick Plume uses the Areal Locations of Hazardous Atmospheres (ALOHA) Model. The plume will be based on most recently reported wind speed, wind direction, and temperature from the closest reporting station. The plume will be based on data for a chlorine spill and the chemical type cannot be changed. Chlorine is used as a representative chemical because it is a light gas, thus representing a worst case scenario.
