A proprietary barrier laminated to a Tyvek® substrateStrong and lightweight, with broad chemical barrierUsed for protection from chemical warfare agentsWidely used by military first responders for weapons of mass destruction situationsTaped seams, attached hood (respirator fit), front zipper closure, storm flap, elastic wrists and attached socksAvailable in sizes Small to 4X-Large; Applications: Because Tychem® F garments are only available with respiratory fit hood, storm flap and taped seams, these garments are intended for domestic preparedness situations where the potential for exposure to chemical warfare agents exists. When the hazard assessment consists of potential for exposure to the FBI's Toxic Industrial Chemicals most likely to be used in a terrorist threat, we suggest consideration of Tychem® CPF 3 or higher protection since permeation data is available on a much broader spectrum of chemicals including chemical warfare agents.
