There are two key procedures for achieving these standards: the <strong>graying<\/strong> and the <strong>blanking<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They are often confused, yet their objectives are complementary. This article explains their differences, their role and their importance in the management of the <strong>particulate and microbiological contamination<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-1\" id=\"h-la-mise-a-gris-preparer-les-surfaces\"><strong>Greying: preparing surfaces<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Visit <strong>graying<\/strong> is a <strong>preparatory stage<\/strong> cleanroom cleaning. It is generally carried out :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>before commissioning or installing sensitive equipment.<\/li>\n\n\n\n<li>after maintenance or construction work,<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-2\"><strong>The steps involved in grayscale upgrading include :<\/strong><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Stop ventilation<\/strong>\n<ul class=\"wp-block-list\">\n<li>Allows suspended particles to fall back.<\/li>\n\n\n\n<li>The air handling unit is then restarted to renew the air.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Rough surface cleaning<\/strong>\n<ul class=\"wp-block-list\">\n<li>Walls, ceilings, floors and furniture are dusted.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Use of suitable detergents<\/strong>\n<ul class=\"wp-block-list\">\n<li>Non-corrosive products, compatible with specific cleanroom surfaces.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">| Result: a rough-cut environment, ready for a thorough disinfection treatment.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Greying is an essential phase in preparing the ground for the <strong>blanking<\/strong>. It ensures that surfaces are clean and free of any coarse particles that could interfere with final disinfection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-3\" id=\"h-la-mise-a-blanc-l-ultime-etape-de-desinfection\"><strong>Blanking: the final disinfection step<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After \u2019mise \u00e0 gris\", comes \"mise \u00e0 blanc\". This more advanced operation aims to achieve a level of\u2019<a href=\"https:\/\/igienair.com\/en\/metiers\/ultra-clean\/\">deep cleaning<\/a>. This step is mandatory before commissioning or restarting a cleanroom, especially after maintenance work or prolonged shutdowns.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-4\"><strong>Blanking steps include :<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Particle decontamination<\/strong> Surface decontamination: Surfaces are subjected to a fine decontamination process, removing not only visible particles, but also those not visible to the naked eye.<\/li>\n\n\n\n<li><strong>Final disinfection<\/strong> Disinfection: This is the in-depth disinfection phase, in which all parts of the room (ceilings, walls, floors, supports, etc.) are treated to eliminate any microbiological or chemical contamination.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Blanking enables rooms to comply with current standards, such as NF EN ISO-14644 and <a target=\"_blank\" rel=\"nofollow\" href=\"https:\/\/www.france-air.com\/guides-et-documents\/hygiene-hospitaliere\/la-norme-nfs-90-351\/\">NF S 90-351<\/a>, and obtain their qualification or requalification. This step is crucial to ensure that the environment is perfectly controlled, minimizing the risk of contamination.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-5\" id=\"h-pourquoi-ces-deux-etapes-sont-indispensables\"><strong>Why are these two steps essential?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ensuring cleanroom quality and compliance.
