Investigation on the Dispersal Patterns of Contaminants in Letters
FIRST RESPONDER GROUP OTTAWA (ONTARIO)

The public health response to bioterrorism incidents involving possibly contaminated letters includes the identification of potentially exposed individuals and an assessment of the need for environmental decontamination. How far could contaminants from handling and opening such letters spread Should decontamination be limited to fomites in the immediate area e.g. desks chairs, floors, clothing, personal effects or should it also encompass a much wider area within a common ventilation system Can cross-contamination of remote areas occur through persons entering and exiting the immediately contaminated area The answers to the questions and the dispersion patterns of contaminants from handling and opening such letters is not known. Such information would enable responders to better define potentially contaminated areas and persons, and guide their decision-making in implementing an appropriate response. This report summarizes the findings of an investigation into the dispersion patterns from envelopes experimentally contaminated with a flourescent tracer powder.
