The Combating Terrorism Technical Support Office (CTTSO), along with other government organizations, continually analyze protective capabilities and emerging technologies to improve PPE for individuals and Collective Protection (ColPro) to shelter multiple people. Entry/exit closure systems are the focus of this Challenge.
Several CBR closure mechanisms exist, however industry typically employs only two types – pressure sealing zippers and multi-track closures. Few materials are capable of being used in construction of CBRN closures, limiting options for new or uncommon applications.
Innovative designs for closure systems will be expected to meet National Fire Protection Association (NFPA) 1994 Class 1 criteria for PPE closures, both as a component and when integrated into a protective system.
