There are three levels of access, each identified by a colour coded sign - red, amber and yellow. The highest risk areas (red and amber) require a licensing process to achieve this status to ensure that all necessary procedures are approved and in place. Yellow areas do not require licensing.

Licensing of Restricted and Highly Restricted Areas

Red (highly restricted) and amber (restricted) areas can only be demarcated as such upon specific authority provided by the Safety Department. This is so as to prevent misuse of this system and so as to ensure that adequate emergency and lone working procedures are in place. In order to apply for a licence for such an area, the the Access Control Application Form can be downloaded and once completed, sent to along with the written procedures requested in the form. As a minimum, all license applications must include an Emergency Response Plan ‌and access control procedures.

Training Documentation

A series of leaflets have been produced aimed at different categories of staff within the College. The leaflets explain exactly what the Access Control coding means to each category of staff. Managers and supervisors should disseminate the leaflets accordingly and use them as a basis for instructing the staff who report to them.
