ABSTRACT

The operational effectiveness of a specific Peripheral Chemosensory Irritants (PCSI) material with respect to its use in peacekeeping needs to be assessed in terms of both the absolute concentration producing incapacitation and the relationship between the incapacitating concentration and the TC50. In a population, the occurrence of a specific response to a PCSI stimulus when plotted as a function of the exposure concentration takes the form of a normal or bell curve, implying the existence of hyposensitive and hypersensitive individuals within that population. Agent Benzylate, a central nervous system depressant, is an atropine-like drug that blocks the muscarinic action of acetylcholine at central and peripheral cholinergic synapses. Screening smokes are usually generated pyrotechnically, and marking agents can be dispersed in solution from large or small-scale dispensers and sometimes mixed with PCSI materials. Aerosolization by thermal volatilization is the most frequently employed method for generating screening smokes and for the dispersion of PCSI materials.
