  • Firefighting and Anhydrous Ammonia - by Harold F. Maybeck

    EVACUATION If ammonia is evident in a downwind direction at the edge of the initial isolation circle, then the isolation zone must be extended out on the downwind side for at least an additional 1000feet (.2miles). The width of this extended isolation zone beyond the initial isolation circle should be equal to the length of the zone, ie. 1000feet.
