In HazMat or CBRN incidents, toxic cloud movement can be affected by wind, solar heating and cooling, humidity and precipitation as well as topographical features. Depending on meteorology, the toxic cloud could be several miles long, but only a few blocks wide. Changing wind patterns could cause the plume to shift, or meander in another direction.
PEAC® Software from Aristatek provides responders with vital information to make informed decisions such as evacuation at an incident scene. Its features include integrated mapping, an easy-to-use toxic or flammable vapor cloud dispersion model, and a comprehensive database of toxic industrial chemicals, biological agents, explosives, and radioactive isotopes. Utilizing a variety of modeling tools, the PEAC System quickly calculates standoff distances and exclusion zones based on actual met data and conditions.
Based on the request of several of our customers, data from CWS weather stations can be integrated automatically to provide on-site met data at an incident. Tualatin Valley Fire and Rescue has used PEAC with their Orion™ Weather Station using a serial connection. Sunnyvale Department of Public Safety and the City of Moorhead Fire Departments utilize Weather Master Software to integrate their Magellan MX™ weather stations.

If a hazardous material produces a vapor cloud that is toxic by inhalation, the PEAC system can calculate a Protective Action Distance (PAD) based on meteorological data and other information available at the scene such as topography and source. Weather stations can be set up to automatically upload and update met data.
