There are sensors which are located in the eyes, ears, chin, cheek, cranium, laryngeal prominence, and side portions of the neck. During a flame exposure, heat flux readings obtained from these sensors are translated to predictions of skin burn injury. This is done using the PyroMan burn translation model, modified to account for differences in skin thickness found in the head region compared with those found in the torso areas of the human body.<\/p>\n\n\n\n<p>PyroHead\u2122 test results are graphically displayed to show the percentage of second and third degree as well as total burn injury, and the spatial distribution of burn predictions for differing sides of the head.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"531\" height=\"342\" src=\"https:\/\/tex-cloud-cdn.nyc3.digitaloceanspaces.com\/textiles-ncsu\/sites\/6\/20231108102218\/pyrohead-02.jpg\" alt=\"A graphic of numbered manikin burn areas alongside burn injury prediction data\" class=\"wp-image-41\" srcset=\"https:\/\/tex-cloud-cdn.nyc3.digitaloceanspaces.com\/textiles-ncsu\/sites\/6\/20231108102218\/pyrohead-02.jpg 531w, https:\/\/tex-cloud-cdn.nyc3.digitaloceanspaces.com\/textiles-ncsu\/sites\/6\/20231108102218\/pyrohead-02-300x193.jpg 300w\" sizes=\"auto, (max-width: 531px) 100vw, 531px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>TPACC has developed a powerful new tool for measuring the thermal protective performance of head and face protective clothing in controlled laboratory fire exposures.
