      There are all kinds of harmful chemicals that are dangerous in different ways. Lots of things are carcinogenic and so can give you cancer. In terms of immediate harm, cyanides kill you very quickly.

      anything can b harmful when it is taken more than a proper threshold dosage. Even ur glucose which u consider as energy giving substance can b harmful if it exceeds 300 mg/ ml dosage. So I must say there is a class which kills instantly includes cyanides, pesticides like phorate, hydroflouric acid (it attacks glass infact borosil glass as well so need special vessels to handle it)
