This NIST funded work will improve our understanding of the risk of structural spot fire ignition in Wildland Urban Interface (WUI) communities. The photo below shows the experimental setup in which a model building is covered in model embers and exposed to the wind. The test highlight regions of a rooftop on which embers can remain in contact with the roof and potential cause ignition. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cecas.clemson.edu\/wind\/wp-content\/uploads\/2020\/12\/ember-removal-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/cecas.clemson.edu\/wind\/wp-content\/uploads\/2020\/12\/ember-removal-768x1024.jpg\" alt=\"\" class=\"wp-image-54\" srcset=\"https:\/\/cecas.clemson.edu\/wind\/wp-content\/uploads\/2020\/12\/ember-removal-768x1024.jpg 768w, https:\/\/cecas.clemson.edu\/wind\/wp-content\/uploads\/2020\/12\/ember-removal-225x300.jpg 225w, https:\/\/cecas.clemson.edu\/wind\/wp-content\/uploads\/2020\/12\/ember-removal-1152x1536.jpg 1152w, https:\/\/cecas.clemson.edu\/wind\/wp-content\/uploads\/2020\/12\/ember-removal-1536x2048.jpg 1536w, https:\/\/cecas.clemson.edu\/wind\/wp-content\/uploads\/2020\/12\/ember-removal-scaled.jpg 1920w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/a><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>\u00a0Ember storms can lead to spot fires starting well ahead of the main fire front and are also one of the leading causes of home destruction.
