Accessibility Statement

All pages on this site are WCAG (Web Content Accessibility Guidelines) compliant and were designed with knowledge of all priority 1 and 2 guidelines of the World Wide Web Consortium (W3C) Web Content Accessibility Guidelines. This site contains many features to help users with disabilities navigate easily. These features are described below. This website is designed for maximum accessibility. Frames are not used, tables are only used for tabulating data and images are kept to a minimum and always described in alt text or with a “null” tag if graphic only.

Standards Compliance

The site uses structured semantic mark-up where possible. For example, internal content pages use H1 for all top level headings and list mark-up for internal navigation where possible. Using real list mark-up is best. Since visual presentation is in the CSS declarations, it does not clutter up the page, so both JAWS and Home Page Reader simply read your list for what it is: a list. However, should you experience difficulty in accessing any of the information on this site, please contact us at [email protected].

General Site Features

Browser Support

This site should display correctly in all current major browsers and has been designed and constructed using Cascading Style Sheets (CSS) for visual layout. This ensures that the contents of each page can still be accessed, even if a user’s browser does not support CSS or has CSS switched off.

Screen Resolution

This site has been designed to make maximum use of screen resolutions measuring 1024 pixels by 768 pixels or greater and is responsive to mobile devices.


All forms and their fields are labelled and arranged into logical groups where possible.

PDF format (.pdf) or Adobe Acrobat format

Some of the information on this website is available in PDF format to provide for easier reading and printing offline. While we will endeavour to render all uploaded Adobe Acrobat PDF files accessible in their creation, this may not be the case with PDF files created by 3rd parties.

Font/Text Sizes

This site makes use of style sheets that allow for flexible resizing of fonts to meet user requirements. If you find that font sizes are too small simply increase the default font size used in your web browser software (for example, in Internet Explorer font sizes can be changed in the View Menu under ‘Text Size’). This feature may not work correctly in all web browsers.

Navigation Aids

Top level navigation is visible at all times. A breadcrumb link is available at the top each page to assist in navigation. The homepage and all internal pages include a search box.


All content images used in the home page and elsewhere include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.

Visual Design

This site uses cascading style sheets for visual layout and all presentation has been completely separated from content with the exception of layout tables. If your browser or browsing device does not support style sheets at all, the content of each page is still readable.


All links, other than PDF’s (unless otherwise notified), open within the same browser window. Should you wish to open a link in a new browser window then hold down the “SHIFT” key while activating the link. OSi is not responsible for the content of any websites owned and operated by third parties to which we may link.
