On the report any deviations or non-conformity will be coded as either a C1, C2 or a C3. Each one has a different level reflecting the possible danger of the problem. That should then reflect the urgency these items are dealt with.

C3 – An issue that requires improvement.
C2 – There is a potentially dangerous issue which requires very urgent remedial action.
C1 – There is a real danger present which presents a likely risk of injury. Immediate remedial action is necessary.

Based on the items above the installation will be marked as satisfactory or unsatisfactory. A satisfactory installation contains no issues or only C3s. Any C1s or C2s will mark the installation as unsatisfactory.
