DETERMINING POTENTIAL FOR PUBLIC IMPACT

STEP 1 : Determine the distance to the toxic or flammable endpoint for the subject chemical. If you are unsure of your endpoint, we recommend that you download EPA's RMP Comp Software which will calculate your endpoint for you.

STEP 2 : If the toxic or flammable endpoint you calculated for your chemical in a worst-case scenario is less than the distance to the nearest public receptor, then you have no potential for public impact. A public receptor means offsite residences, institutions (e.g. schools, hospitals), industrial, commercial and office buildings, parks, or recreational areas inhabited or occupied by the public at any time without restriction by the stationary source where members of the public could be exposed to toxic concentrations, radiant heat, or overpressure, as a result of an accidental release.
