So it\u2019s important to know the identification and\nclassification of Hazardous Waste. These wastes pose potential risks to living\norganisms or human health due to the fact that they are:<\/p>\n\n\n\n<ul>\n<li>Non-degradable or persistent in\nnature;<\/li>\n\n\n\n<li>Can be biologically expanded;<\/li>\n\n\n\n<li>They are highly toxic &amp;\neven lethal at very low concentrations.<\/li>\n<\/ul>\n\n\n\n<p>These\nlists relate only to the intrinsic hazard of the waste, under uncontrolled\nrelease, to the environment, regardless of pathways\/quality to humans or other\nvital organisms such as animals &amp; plants. The basic criteria used to know\nthe nature of the hazard is phytotoxicity, bio-concentration, toxicity, and\ngenetic activity. The danger to public health &amp; the environment of a given\nhazardous waste is dependent on the quantity &amp; characteristics of the waste\ninvolved. <\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_82_2 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title ez-toc-toggle\" style=\"cursor:pointer\">Page Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-toggle-hide-by-default' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/corpbiz.io\/learning\/classification-of-hazardous-waste\/#What_are_Hazardous_Wastes\" >What are\nHazardous Wastes?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/corpbiz.io\/learning\/classification-of-hazardous-waste\/#Characteristics_of_Hazardous_Wastes\" >Characteristics\nof Hazardous Wastes<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/corpbiz.io\/learning\/classification-of-hazardous-waste\/#What_is_the_Classification_of_Hazardous_Waste\" >What is the\nClassification of Hazardous Waste?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/corpbiz.io\/learning\/classification-of-hazardous-waste\/#Conclusion\" >Conclusion<\/a><\/li><\/ul><\/nav><\/div>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_are_Hazardous_Wastes\"><\/span>What are\nHazardous Wastes?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Before\nwe discuss the identification and classification of hazardous wastes, let&#8217;s\nunderstand the meaning of hazardous wastes. Hazardous wastes are those that may\ninclude toxic substances generated from the hospital, industrial, some types of\nhousehold wastes. These wastes could be inflammable, explosive, corrosive, or\nreact when exposed to other materials. <\/p>\n\n\n\n<p>The management of hazardous wastes has become a specialised discipline because of the difficult nature of the problem &amp; the solutions available to humanity. The mismanagement examples of hazardous wastes causing tragic environmental &amp; human outcomes are numerous. The management process of hazardous wastes is based on the definition &amp; classification of hazardous wastes and their toxic effects on humans &amp; taking into consideration the application of risk management to control human health &amp; environmental impacts of hazardous wastes. Hence, <a href=\"https:\/\/corpbiz.io\/hazardous-waste-management-authorization\"><strong>Hazardous Waste Management<\/strong><\/a> deals with minimising harmful effects on humans &amp; the environment by applying special techniques of storage, treatment, handling, transportation, and disposal of hazardous wastes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Characteristics_of_Hazardous_Wastes\"><\/span>Characteristics\nof Hazardous Wastes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The\nregulations specify characteristic hazardous wastes as wastes that exhibit\nmeasurable properties posing enough threats to warrant regulations. For a waste\nto be considered a characteristic hazardous waste, it must cause or knowingly\ncontribute to increased mortality or an increase in serious irreversible or\nincapacitating reversible illness or pose a significant threat to humans and\nthe environment when it&#8217;s improperly treated, transported, disposed of, stored,\nor otherwise mismanaged. In other terms, if the wastes generated at a facility\nare not listed in F, K, P, or U lists, the final step to finding out whether a\nwaste is hazardous is to estimate it against the following 4 hazardous\ncharacteristics:<\/p>\n\n\n\n<ol>\n<li><strong><em>Corrosivity<\/em><\/strong>:\nA liquid waste that has a pH of less than\/equal to 2 or greater than\/equal to\n12.5 is deemed to be corrosive hazardous waste. Sodium Hydroxide (NaOH), a\ncaustic solution with a high pH, is often used by many industries to\nclean\/degrease metal parts. <\/li>\n\n\n\n<li><strong><em>Ignitability:<\/em><\/strong>\nA waste is an ignitable or burnable hazardous waste, if it has a flashpoint of\nless than 60C, easily catches fire &amp; burns so vigorously as to create a\nhazard or is an intangible compressed gas or an oxidiser. <\/li>\n\n\n\n<li><strong><em>Toxicity<\/em><\/strong>:\nTo know if waste is toxic or not, a representative sample of the material\nshould be subjected to a test or examination conducted in a certified or\nauthorised laboratory. The toxic characteristic recognises wastes that are\nlikely to seep dangerous concentrations of toxic chemicals into groundwater.<\/li>\n\n\n\n<li><strong><em>Reactivity<\/em><\/strong>:\nA material is regarded as a reactive hazardous waste if it&#8217;s unstable, reacts\naggressively with water, creates toxic gases when exposed to water\/corrosive\nmaterials, or if it&#8217;s capable of explosion when exposed to heat or a flame.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_the_Classification_of_Hazardous_Waste\"><\/span>What is the\nClassification of Hazardous Waste?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Following\nis the classification of hazardous waste:<\/p>\n\n\n\n<ol>\n<li><strong><em>Radioactive Substance<\/em><\/strong>: These substances are those substances that emit ionising radiation and these substances are hazardous because lengthy exposure to radiation often results in damage to living organisms. Such substances are of special concern because they continue for a long period. The period in which <strong>radiation<\/strong> happens is commonly measured &amp; expressed as half-life, i.e., the time needed for the radioactivity of a given amount of the substance to decay to half its initial value. <\/li>\n\n\n\n<li><strong><em>Biomedical Wastes<\/em><\/strong>: The primary sources of hazardous biological wastes are biological &amp; hospitals research facilities. The ability to infect other living organisms &amp; the ability to produce toxins are the most noteworthy characteristics of hazardous biological wastes.<\/li>\n\n\n\n<li><strong><em>Chemicals<\/em><\/strong>: Most dangerous chemical wastes can be categorised into different groups:&nbsp; inorganic metals, flammables, acids &amp; bases, synthetic organics, and explosives. Some of the chemicals are dangerous because they are highly toxic to most life forms. When such hazardous compounds or elements are present in a waste stream at levels equal to or greater than their threshold levels, the overall waste stream is recognised as dangerous.<\/li>\n\n\n\n<li><strong><em>Flammable Wastes<\/em><\/strong>: such wastes are also recognised as hazardous chemical wastes. This dual grouping is vital because of the high potential hazard in collecting, robust, and disposing of flammable wastes. Such wastes may be liquid, solid or gaseous, but most often, they are liquids. <\/li>\n\n\n\n<li><strong><em>Explosives<\/em><\/strong>: such hazardous wastes are primarily ordnance (artillery) materials, i.e., the wastes resulting from ordnance manufacturing &amp; some industrial gases. Similar to flammables, these wastes also have a high potential for hazard in storage, disposal, collection; therefore, they should be regarded separately in addition to being listed as hazardous chemicals. This waste may exist in liquid, gaseous, or solid. <\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>After discussing the classification of hazardous waste, it\u2019s clear that wastes are secondary materials, which are usually categorised into six different categories as inherently waste such as spent materials, by-products, scrap metals, and commercial chemical products. Solid wastes from a subset of all hazardous wastes &amp; secondary materials.
