Key Information is Needed to Drive IMAAC Plume Modeling Analyses Provide as much information as possible when
requesting assistance Essential information (initial product):
o Location of release (e.g., latitude/longitude, street address)
o Time of release
Other key information (effects products): o Type of material (e.g., biological agent, bio-toxin, toxic
industrial chemical, chemical agent, radiological isotopes) o Type of release (e.g., spill, fire, explosion) o Amount released or at risk (e.g., 90 ton rail car, 1000 Curies,
2 lbs) o Observations related to the initial plume (e.g., height of
plume, size of crater)
Do not delay in contacting the center in order to collect this information
