This report contains information related to the testing of commercially available chemical protective suits. The information contained in this report is intended for use by law enforcement patrol officers in the event of a terrorist attack that involves the use of Chemical Warfare Agents (CWA). Additionally, this information may also be applicable for Emergency Medical Services (EMS) personnel and other first responders at this type of incident. For easy dissemination, this report is available at the following web-site: http://www.nbc-prepare.org. This report covers Man In Simulant Testing (MIST) of the following commercially available, Level C chemical protective suits: the Tyvec Protective Wear suit (garage-type, for mechanics), the Kappler CPF4 suit (model # 4T434), the TyChem 9400 (style 94160) suit, the TyChem SL (style 72150) suit, and the Tyvec ProTech F suit. These suits are being considered by law enforcement agencies for use at scenes where chemical warfare agents have been used by terrorists. This testing examined how well the complete protective suit ensembles protect the wearer against vapor adsorption at the skin by exposing test participants wearing the suits to a chemical agent simulant (methyl salicylate) and measuring the Physiological Protective Dosage Factor (PPDF) the wearers received while performing a set of typical law enforcement activities. The results showed that the suits provided the wearers an average Overall Physiological Protective Dosage Factor (PPDF) of: standard police uniform - 2.0; Tyvec - 4.0; CPF4 - 17.6; TyChem 9400 - 16.5; TyChem SL - 23.7, and the Tyvec ProTech F - 41.8.
