ABSTRACT:
The present invention provides an apparatus for determining and directing community response to a material release, such as a hazardous gas release. The apparatus includes a map with a rotatable warning indicator attached thereto.
The warning indicator has one or more warning areas marked thereon and preferably color coded. The warning indicator also includes at least one wind direction indicator which may be aligned with a heading on the map which corresponds to the actual wind condition. When so aligned the warning areas highlight the geographical area on the map where a community response is suggested and recommends what first response precautions should be taken.
