As a first responder, strong consideration should be given to calling local hospitals to see if additional causalities with similar symptoms have been observed. A biological attack is the deliberate release of germs or other biological substances that can make you sick.
Heat Emitting Material Material that seems to emit heat without any sign of a external heating source. Many sick or dead birds, fish or small animals are also cause for suspicion. In the case of a biological incident, the onset of symptoms requires days to weeks and there typically will be no characteristic signatures. Sprinkle the flour or powder liberally over the affected skin area, wait 30 seconds, and brush off with a rag or gauze pad. If opened, letters allegedly containing anthrax or another toxin should be handled carefully.
