Rail engineering works: 15 & 16 November
It is the responsibility of all employers to ensure that relevant Operational Safety Instructions (OSIs) are brought to the attention of their staff. However, individuals remain responsible for their own actions and those who are in any doubt should consult their supervisor or manager.
This page contains all current OSIs, downloadable in PDF format. The subject matter of the OSIs has been reviewed and those no longer of relevance, or which are considered to be sufficiently promulgated, have been deleted without replacement.
