(UL) Directory defines wetting agents as: \u201cliquid concentrates which, when added to plain water in proper quantities, materially reduce the surface tension of plain water and increases its penetration and spreading ability.\u201d Water to which a wetting agent has been added to is sometimes referred to as \u201cwet water\u201d because of its increased ability to wet surfaces it is applied to. <\/p>\n\n\n\n<p>So far, we know that water becomes &#8220;wetter&#8221; by lowering its surface tension. The surface tension of water defines its behavior.  By making the water wetter we benefit economically because we maximize its efficiency, thus we need less water to put down fires. On top of it all, the wetting agents are biodegradable and pose no risk to the environment and living things.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img loading=\"lazy\" src=\"https:\/\/i2.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?fit=696%2C465&amp;ssl=1\" alt=\"\" class=\"wp-image-923\" width=\"613\" height=\"410\" srcset=\"https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?w=2247&amp;ssl=1 2247w, https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?resize=300%2C200&amp;ssl=1 300w, https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?resize=768%2C513&amp;ssl=1 768w, https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?resize=1024%2C684&amp;ssl=1 1024w, https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?resize=696%2C465&amp;ssl=1 696w, https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?resize=1068%2C713&amp;ssl=1 1068w, https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?resize=629%2C420&amp;ssl=1 629w, https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?resize=1920%2C1282&amp;ssl=1 1920w, https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?w=1392 1392w, https:\/\/i1.wp.com\/thebrainmaze.com\/wp-content\/uploads\/2019\/10\/firefighter-2.jpeg?w=2088 2088w\" sizes=\"(max-width: 613px) 100vw, 613px\" \/><\/figure><\/div>\n\n\n\n<p>Sources: <a href=\"https:\/\/www.fireengineering.com\/1947\/12\/01\/264255\/wetting-agents-in-fire-service\/#gref\">Fire Engineering<\/a>, <a href=\"https:\/\/ifpmag.mdmpublishing.com\/firefighting-foam-making-water-wetter\/\">International Fire Protection<\/a>, <a href=\"http:\/\/www.directchem.com\/061waterwetter.html\">Direct Chem<\/a><\/p>\n\n\n\n<p> <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Firefighters in many places have embraced the use of &#8220;wetting agents&#8221; as part of their everyday operational tactics.&nbsp;In order to be more efficient in their work of distinguishing fires, they have recently started adding certain chemicals to the water.
