BRGM undertakes to make its internet, intranet and extranet sites and its software packages accessible (along with its mobile apps and digital street furniture), in accordance with Article 47 of Act no. 2005-102 of 11 February 2005.

To this end, BRGM is implementing the following strategy and actions:

  • Publication of the multi-annual accessibility strategy (currently being drafted);
  • Publication of the 2024-2026 action plans (currently being drafted).

This accessibility declaration applies to the www.brgm.fr website.

Compliance status

The www.brgm.fr website does not comply with Version 4 of the General Framework for Improved Accessibility (RGAA) due to the non-conformities and exemptions listed below.

Test results

The compliance audit carried out by AccessProd revealed that:

  • 35.21% of the criteria in Version 4.1.2 of the RGAA are met;
  • the average compliance rate for the online service is 48.5%. This is the average of the compliance rates obtained for all the pages in the sample.

This percentage corresponds to:

  • 46 non-compliant criteria;
  • 25 compliant criteria;
  • 35 inapplicable criteria.

Inaccessible content

Non-conformities

  • Some external modules are not fully compatible with assistive technologies, such as:
  • the "Tarteaucitron" cookie manager (button contrasts, poor semantics of tags);
  • the "Calaméo" document reader (image and script rendering, poor semantics of tags, list structure, visibility of keyboard navigation, information presentation, field labels, field grouping);
  • "Leaflet" interactive maps (titles of links and buttons, script rendering).
  • tab-based display systems;
  • numerous interface buttons;
  • buttons for closing modal windows displayed over the page;
  • the different fields on the site search function;
  • slide shows;
  • customised tooltips;
  • the button to return to the top of the page;
  • rendering of modal windows;
  • the reset button for the star rating system.
  • Some images are not correctly ignored by assistive technologies when they are purely decorative.
  • Some text alternatives to images are irrelevant.
  • Some images do not have a detailed description.
  • Some image captions are not rendered correctly.
  • The frames of video players and document readers are not clearly identifiable by text-to-speech.
  • Some information on image maps is only conveyed by colour.
  • The contrast ratios of certain text and interface components are not always high enough.
  • Some videos have no text transcripts. The text transcript of the "MétéEAU Nappes" video does not contain the text as an image.
  • Videos are not subtitled in English when this is the language of the page.
  • The videos do not have audio description where necessary.
  • The text content adjacent to the videos does not enable individual media to be clearly identified.
  • The column headers of some data tables are not rendered correctly.
  • Some tables are used to format content.
  • Some links are not explicit and are poorly vocalised by assistive technologies.
  • Some links have tooltips that do not include at least the visible title of the link.
  • Some scripts need to be corrected in order to be compatible with assistive technologies and keyboard navigation, such as:
  • Search results are not updated correctly.
  • Status messages displayed in real time without the page being reloaded when sending forms are not rendered correctly.
  • The source code of the pages is not always valid and can cause rendering problems.
  • Texts in a language other than the page's default language are not identifiable as such.
  • Page titles (browser tabs) are not relevant when filtered searches are performed or when data input errors are made in forms.
  • Structure tags are used for the layout of paragraphs of text.
  • Line breaks in the "Tarteaucitron" cookie management panel are only used for presentation purposes.
  • Some levels of titles do not follow a logical order, causing errors in the hierarchy between titles.
  • The main navigation area and the summaries are not structured correctly from a technical point of view.
  • Some lists of items are not structured correctly.
  • Some attributes used to present information appear in the generated source code of certain pages.
  • Text is not always visible when the font size or graphic zoom is increased by up to 200%.
  • Declarations of element background and font colours are not used correctly.
  • Some links are not visible enough in relation to the surrounding text.
  • Keyboard navigation is not always visible.
  • Some visible content is hidden from assistive technologies.
  • The breadcrumb trail gives an indication by form alone.
  • Custom tooltips become unavailable if the pointer is no longer on the component or on this tooltip.
  • Some form fields do not have correctly associated labels.
  • Some fields of the same type are not grouped together.
  • Required fields in the newsletter registration form are indicated with an asterisk, which is not understandable to all users. The meaning is only given after the validation button.
  • The auto-completion of form fields containing user data is not compliant.
  • There is an avoidance link, but it is not visible.
  • The tab order is not always consistent.
  • Not all downloadable files are compatible with assistive technologies.
  • Viewing a lot of content requires the use of complex gestures, with no alternative using simple gestures when performing a graphical zoom or when the screen size is reduced.
