Blauer's HZ9420 Multi-Threat ensemble offers the highest level of protection in the Homeland Defender® line from liquid, vapor, and particulate forms of CBRN challenge agents. The HZ9420 is made of GORE® CHEMPAK® Ultra-barrier fabric and is certified to NFPA 1994 (2007 Ed.) Class 2 for protection against chemical warfare agents (CWAs) and toxic industrial chemicals (TICs) at concentrations at or above IDLH when worn with approved SCBA systems and footwear. For added protection, this revolutionary non-permeable membrane is laminated to a 4.5 ounce NOMEX IIIA outer shell, which provides excellent static dissipative performance and resists melting, dripping, and burning when exposed to high heat and flame.
Superior Heat Stress Management First responders and HAZMAT teams typically must deal with heat stress and elevated core body temperatures caused in large part by their PPE ensembles, which trap body heat and interfere with the body's sweat response. The HZ9420 Multi-Threat suit effectively alleviates this problem through a unique evaporative cooling capability. The NOMEX® IIIA outer shell has been engineered to absorb water without affecting the integrity or protective performance of the underlying GORE® CHEMPAK® barrier. By wetting the suit down with water before or during use, the wearer benefits from a natural cooling effect similar to sweating as the water evaporates from the outer shell.
