In this article we will look at some factors that can invalidate the system once it is installed.<\/p>\n\n<h2 class=\"wp-block-heading\">Is a Certified System Always Safe?<\/h2>\n\n<p class=\"wp-block-paragraph\">In theory, when a system is <a href=\"https:\/\/ypsossafety.com\/como-saber-si-un-epi-esta-certificado-para-trabajos-en-altura\/\">certified <\/a>as fit for use, it is safe to use, but on rare occasions we may find that this is not entirely true.<\/p>\n\n<h3 class=\"wp-block-heading\">What Does It Mean for a System to Be Certified?<\/h3>\n\n<p class=\"wp-block-paragraph\">We must first distinguish between the certification provided by a manufacturer, meaning it is manufactured and tested in accordance with current regulations, and the installation certification issued by an installation company, meaning it is installed in accordance with regulations.<\/p>\n\n<h3 class=\"wp-block-heading\">Installation Certification Process<\/h3>\n\n<p class=\"wp-block-paragraph\">Focusing on the latter, installation certification, it will differ depending on the type of fall arrest system, but for an installation to be correct the following must be taken into account:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/ypsossafety.com\/que-formacion-debe-tener-el-instalador-de-sistemas-anticaidas\/\">Training <\/a>and accreditation of the installation company<\/strong>: Most fall arrest system manufacturers train installers so that they can assemble their products, and accredit them to do so<\/li>\n\n\n\n<li><strong>Qualified technician<\/strong>: A technician, such as an engineer, validates the installation and adds the date and signature<\/li>\n\n\n\n<li><strong>Detailed documentation<\/strong>: When a system is installed, all related information is attached: technical data sheet, project, necessary calculations, &#8230;<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">What Does a System&#8217;s Installation Certification Include?<\/h3>\n\n<p class=\"wp-block-paragraph\">For an installation to be certified and fit for use, several steps must have been followed, such as:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Correct anchors and fasteners<\/strong>: Both in terms of the type used, which must be detailed in the system manufacturer&#8217;s manuals, and in being the ideal ones for the surface where they are installed<\/li>\n\n\n\n<li><strong>Environment assessment<\/strong>: The installed system must be the most suitable for the environment where the <a href=\"https:\/\/ypsossafety.com\/trabajo-en-altura\/\">work at height<\/a> will later be carried out; the system may be properly installed yet still not guarantee the worker&#8217;s safety in the event of a fall<\/li>\n\n\n\n<li><strong>Testing<\/strong>: In some cases, such as EN795A anchor points, load tests must be performed with a pull-out tester as required by the standard<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">Installation Errors That Invalidate the System<\/h2>\n\n<p class=\"wp-block-paragraph\">As mentioned, even if the system has been tested and certified by the manufacturer and signed off as fit for use by an installer, various scenarios can occur that invalidate it:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Incorrect anchors<\/strong>: This happens when the ones specified by the manufacturer have not been used; for example, a screw with a smaller metric size than the manufacturer indicates in its manual could invalidate the system<\/li>\n\n\n\n<li><strong>Poor assembly of components:<\/strong> If they are assembled in the wrong order or by forcing the elements in a way that alters their structure, the system might not be fit for use<\/li>\n\n\n\n<li><strong>Not respecting safety distances<\/strong>: One error that can occur is, for example, exceeding the maximum distance between posts specified by the manufacturer in the case of <a href=\"https:\/\/ypsossafety.com\/ananke\/\">guardrails<\/a>; this distance is usually indicated in each manufacturer&#8217;s assembly manuals<\/li>\n<\/ul>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"497\" height=\"280\" src=\"https:\/\/ypsossafety.com\/wp-content\/uploads\/2026\/01\/image.png\" alt=\"\" class=\"wp-image-16307\" style=\"aspect-ratio:1.7750022958949399;width:474px;height:auto\" srcset=\"https:\/\/ypsossafety.com\/wp-content\/uploads\/2026\/01\/image.png 497w, https:\/\/ypsossafety.com\/wp-content\/uploads\/2026\/01\/image-300x169.png 300w\" sizes=\"(max-width: 497px) 100vw, 497px\" \/><\/figure>\n<\/div>\n<p class=\"has-text-align-center wp-block-paragraph\"><em>Example of an Ananke Plate assembly manual showing the maximum distance between posts<\/em><\/p>\n\n<h3 class=\"wp-block-heading\">What Happens When a System Is Poorly Installed<\/h3>\n\n<p class=\"wp-block-paragraph\">Installation <a href=\"https:\/\/ypsossafety.com\/principales-errores-que-ponen-en-peligro-a-los-trabajadores-en-altura\/\">errors<\/a> may go unnoticed if no accident occurs, but if a fall does happen they can have very serious consequences.<\/p>\n\n<h4 class=\"wp-block-heading\">What Are the Consequences of an Installation Error?<\/h4>\n\n<p class=\"wp-block-paragraph\">A poorly installed fall arrest system puts workers&#8217; safety at risk, since it may be ineffective at stopping a fall, so one of the main consequences is the injuries workers may suffer if an accident occurs.<\/p>\n\n<p class=\"wp-block-paragraph\">Another consequence involves the manufacturer&#8217;s warranty: if the system was installed without following the manufacturer&#8217;s instructions, the manufacturer may not take responsibility for defective parts, and the warranty would therefore be voided.<\/p>\n\n<h4 class=\"wp-block-heading\">Who Is Liable If an Accident Occurs?<\/h4>\n\n<p class=\"wp-block-paragraph\">In the <a href=\"https:\/\/ypsossafety.com\/que-hacer-en-caso-de-un-accidente-en-altura\/\">case of fall accidents<\/a>, when a previously installed system exists, they are subject to an internal or external investigation to determine at which point in the chain faults may have been committed.<\/p>\n\n<p class=\"wp-block-paragraph\">If the system has the corresponding tests and certificates in accordance with the standard, but was installed without following the current regulations or the manufacturer&#8217;s manual, it is the installation company that must answer for it.<\/p>\n\n<p class=\"wp-block-paragraph\">That is why it is crucial for both manufacturers and installers of fall arrest systems to abide by the standards and technical requirements, thus helping to ensure a safe working environment.<\/p>\n\n<h3 class=\"wp-block-heading\">How to Avoid Errors Before Installing<\/h3>\n\n<p class=\"wp-block-paragraph\">So that the installation company can avoid errors and the fall arrest system works properly in the event of an accident, a number of measures can be implemented to minimize potential risks:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Review the installation environment<\/strong>: Check the structure and the surface, and that it is compatible with the system to be installed<\/li>\n\n\n\n<li><strong>Materials verification<\/strong>: Make sure the system components supplied by the manufacturer are in good condition and optimal for the location; for example, stainless steel would be the most suitable in coastal areas<\/li>\n\n\n\n<li><strong>Essential documentation<\/strong>:<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Part of the <a href=\"https:\/\/ypsossafety.com\/que-documentacion-entregar-tras-instalar-un-sistema-de-seguridad-en-altura\/\">technical documentation<\/a> for an installation comes from the manufacturer, and the installer must make sure they have it:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>System technical data sheet<ul><li>System assembly manual<\/li><\/ul>\n<ul class=\"wp-block-list\">\n<li>System test certificates in accordance with the standard<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Another important part is the documentation the installation company itself prepares about the project, such as:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>System calculations<\/li>\n\n\n\n<li>Installation drawings<\/li>\n\n\n\n<li>Installation certificate<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">When Should You Consult the Manufacturer?<\/h3>\n\n<p class=\"wp-block-paragraph\">When the installation company has questions about the installation process, the most suitable fall arrest system to install or, for example, if the project has atypical characteristics, we recommend consulting the manufacturer.<\/p>\n\n<p class=\"wp-block-paragraph\">At <a href=\"https:\/\/ypsossafety.com\/\">Ypsos <\/a>we are happy to help and advise our customers with the installation of our systems, making our team available to provide technical support and so help ensure that all safety standards are met. If you have any questions, you can <a href=\"https:\/\/ypsossafety.com\/contacto-ypsos\/\">contact us<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Conclusion<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">The manufacturer&#8217;s certification of a fall arrest system is as crucial as the one performed by an installer, since both certifications, when done correctly, ensure that the system&#8217;s end user suffers as few injuries as possible in the event of an <a href=\"https:\/\/ypsossafety.com\/quien-es-responsable-en-un-accidente-en-altura\/\">accident <\/a>. Following the manufacturer&#8217;s instructions, meeting the regulatory requirements and carrying out the necessary checks helps avoid errors that can have fatal consequences.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As fall arrest system manufacturers, we know that a fundamental part of making sure devices work properly is using quality materials, testing the products and holding the corresponding certifications.
