Although not generally used or recommended on Class C fires, F-500 EA has been thoroughly tested on high-voltage lithium-ion battery fires and transformer fires.<\/p>\n<p>Most of the lithium-ion battery fire testing was conducted in Germany by Bosch Group, DEKRA Automobile GmbH, Daimler AG and Deutsche ACCUmotive GmbH &amp; Co. KG and endorsed by the State Fire School Baden-Wurttemberg. They concluded that F-500 EA was the best agent available to extinguish high-voltage battery car fires due to its ability to cool and extinguish the batteries, as well as modern automobile plastic and magnesium components and fuels.[\/vc_toggle][vc_toggle title=&#8221;What solution percentages of F-500 EA do you need?&#8221; css=&#8221;&#8221;]F-500 EA is commonly used at \u00bd \u2013 1% on Class A fires, and 3% on polar and nonpolar Class B fires, Class D fires and some Class C fires, such as high-voltage hybrid and electric car batteries and energized transformers (consult F-500 EA SOG\u2019s before fighting transformer fires).<\/p>\n<p>Although F-500 EA can quickly extinguish a Class B fire, this is not to be confused with \u201cfuel spill neutralization.\u201d To encapsulate an entire hydrocarbon fuel spill, you need to know how much fuel has been spilt. The ratio is 1 part F-500 EA; 8 parts fuel and 40 parts of water. A typical fuel spill on a road of 8 gallons would require one gallon of F-500 EA and 40 gallons of water to render the spill harmless; nonflammable and nonignitable. It can be safely vacuumed or left to evaporate, depending on local regulations.[\/vc_toggle][vc_toggle title=&#8221;Is F-500 EA like foam?&#8221; css=&#8221;&#8221;]Although F-500 EA shares some surface tension reduction properties of a wetting agent, F-500 EA is neither a wetting agent nor a foam. F-500 is an \u201cEncapsulator Agent.\u201d<\/p>\n<p>A foaming agent creates a foam blanket that smothers a fire, depriving the fire of oxygen. This is one element of the fire tetrahedron. F-500 EA extinguishes a fire by eliminating three legs of the fire tetrahedron. Although F-500 EA does not smother a fire, it does rapidly cool the fire \u2013 remove the heat; remove the fire. F-500 EA also encapsulates the fuel, rendering it nonflammable and nonignitable.<\/p>\n<p>Finally, F-500 EA inhibits the free radical chain reaction, which is a chemical reaction resulting from the energy created by the fire. These flammable off-gases are also encapsulated. Eliminating any one element of the fire tetrahedron can extinguish a fire \u2013 F-500 EA eliminates three elements.[\/vc_toggle][vc_toggle title=&#8221;What is the shelf life of F-500 Encapsulating Agent?&#8221; css=&#8221;&#8221;]The shelf life of F-500 EA is at least 15 years, assuming the container has not been opened. Testing is ongoing.[\/vc_toggle][vc_toggle title=&#8221;F-500 EA safe for the environment?&#8221; css=&#8221;&#8221;]<strong>Nontoxic and Non-Skin Sensitizing<\/strong><br \/>\nF-500 was found to be non-sensitizing when tested in accordance with OECD-406.<\/p>\n<p><strong>Nonhazardous<\/strong><br \/>\nF-500 EA contains no ingredients reportable under Superfund Amendments and Reauthorization Act (SARA) Title III, Section 313 of 40 CFR-372 or the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) as of July 1, 1995. F-500 EA is discarded as non-hazardous waste under RCRA CFR261.<\/p>\n<p><strong>Fully Biodegradable<\/strong><br \/>\nTesting shows that F-500 EA is 100% fully biodegradable. As with any substance, care should be taken to prevent uncontrolled discharge from entering groundwater, surface water or storm drains. With advance notice, F-500 EA can be treated by local biological wastewater treatment plants.<\/p>\n<p>The lower the Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD), the lower the demand for oxygen and the better for the aquatic ecosystem. F-500\u2019s BOD is 87% less and COD is 80% less than that of several AR-AFFF products.<\/p>\n<p><strong>EPA NCP Product Schedule Listed<\/strong><br \/>\nF-500 EA is listed on the National Contingency Plan Product Schedule of the U.S. Environmental Protection Agency as a surface washing agent.[\/vc_toggle][vc_toggle title=&#8221;For how long as F-500 EA been sold?&#8221; css=&#8221;&#8221;]F-500 EA has been sold globally since 1997 and has gained worldwide recognition as a unique firefighting and spill control tool.[\/vc_toggle][vc_toggle title=&#8221;Why should be choose F-500 EA over traditional foam?&#8221; css=&#8221;&#8221;]We feel F-500 EA is a more versatile product. The same F-500 EA can be used on Class A, Class B polar, Class B nonpolar, Class C (transformers and high-voltage car fires) and Class D fires. Three different foams are required for Class A, Class B polar and Class B nonpolar. Additional products are generally used on Class C and D. And then there\u2019s three-dimensional fires.<\/p>\n<p>NFPA 11 specifically states \u201cFoam is not suitable for three-dimensional flowing liquid fuel fires or for gas fires.\u201d Because the foam blanket traps in the heat, foam is very poor at cooling. Also, much more agent and water is required for foam over F-500 EA. You can expect fewer callbacks for rekindles because F-500 EA reduces the temperature below autoignition temperatures. Also, F-500 EA doesn\u2019t create the scalding steam associated with fire extinguishment; instead, F-500 EA results in a warm vapour at about 140\u00b0F. That alone can mean fewer workman\u2019s comp claims.<\/p>\n<p>As F-500 EA encapsulates the free radicals, there is less toxic smoke and improved visibility. Finally, for hydrocarbon spills, F-500 EA encapsulates the fuel, making it safe, whereas foam needs to be re-applied to prevent the blanket from breaking down.[\/vc_toggle][vc_toggle title=&#8221;Can F-500 EA be used on Class C fires?&#8221; css=&#8221;&#8221;]Most of the lithium-ion battery fire testing was conducted in Germany by Bosch Group, DEKRA Automobile GmbH, Daimler AG and Deutsche ACCUmotive GmbH &amp; Co.

The F-500 EA water droplets are attracted to the hydrocarbon molecules and surround them, forming micelles or \u201dchemical cocoons.\u201d Although the fuel still exists and can be physically separated from the F-500 EA, it is nonflammable and non-ignitable and will generally remain that way until it evaporates.[\/vc_toggle][vc_toggle title=&#8221;Where can I buy F-500 EA in South Africa?&#8221; css=&#8221;&#8221;]We have service centres in Johannesburg, Durban and Cape Town, and can supply F-500 EA nationally. <a href=\"https:\/\/www.fireservice.co.za\/new\/contacts\/\">Contact us<\/a> directly for a quote and further details.[\/vc_toggle][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;2486&#8243; img_size=&#8221;full&#8221; css_animation=&#8221;bounceInRight&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row gap=&#8221;10&#8243; inverse=&#8221;&#8221; css=&#8221;.vc_custom_1727636580608{margin-top: 50px !important;margin-bottom: 100px !important;}&#8221;][vc_column][vc_images_carousel images=&#8221;2502,2508,2507,2506,2505,2504,2503&#8243; img_size=&#8221;full&#8221; onclick=&#8221;link_no&#8221; speed=&#8221;3000&#8243; slides_per_view=&#8221;7&#8243; hide_pagination_control=&#8221;yes&#8221; hide_prev_next_buttons=&#8221;yes&#8221; wrap=&#8221;yes&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row full_width=&#8221;stretch_row&#8221; inverse=&#8221;&#8221; css=&#8221;.vc_custom_1553455072471{margin-top: 50px !important;padding-bottom: 50px !important;background-color: #c40813 !important;}&#8221;][vc_column][vc_column_text css=&#8221;.vc_custom_1553767739228{margin-top: 3em !important;margin-bottom: 3.5em !important;}&#8221;]<\/p>\n<h3 style=\"text-align: center;\"><span style=\"color: #ffffff;\">HOTLINE: 011 882 2111 \/ 082 257 1180<\/span><\/h3>\n<p>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row full_width=&#8221;stretch_row_content&#8221; parallax=&#8221;content-moving&#8221; parallax_image=&#8221;2498&#8243; inverse=&#8221;&#8221; css=&#8221;.vc_custom_1727635101115{padding-top: 200px !important;padding-bottom: 200px !important;}&#8221;][vc_column][\/vc_column][\/vc_row][vc_row inverse=&#8221;&#8221; css=&#8221;.vc_custom_1553452788444{margin-top: 50px !important;margin-bottom: 50px !important;}&#8221;][vc_column][vc_empty_space height=&#8221;30px&#8221;][\/vc_column][\/vc_row][vc_row gap=&#8221;10&#8243; inverse=&#8221;&#8221; css=&#8221;.vc_custom_1727633089471{margin-top: 50px !important;margin-bottom: 100px !important;}&#8221;][vc_column width=&#8221;2\/3&#8243;][vc_toggle title=&#8221;What types of fires can F-500 EA extinguish?&#8221; css=&#8221;&#8221;]F-500 EA is UL listed for use on Class A and Class B fires, although F-500 EA has been used successfully on [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-2539","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.1 -
