***the indication for anti-platelet agents is typically cardiovascular disease. Antiplatelet agents are not considered anticoagulants but examinees taking them will be

unfit for work on NUIs because of the presence of a history of cardiovascular disease.

Even if medical examiners are not specifically requested to assess fitness for work on NUI, the guidelines for each of these situations indicate where the certificate should be annotated ‘unfit for work on NUI without direct operator medical advisor approval’. However, the location, transport arrangements, facilities and deployed personnel for normally unmanned installations vary, and operator medical advisors may permit mobilisation on a case-by-case basis at their discretion.
