On a project such as this, where engineers are working with contractor’s personnel that they don’t know, Health and Safety is of paramount importance.
All personnel attending site (whether working on specific tasks, or visiting) had to comply with the safe systems of work as set out in this RAMS document in order to achieve the H&S objectives.  All site personnel needed to attend a site induction be presented by our Site Engineer prior to commencing works on site. The RAMS document was used to provide the context and content of the site induction briefing.  All site personnel were required to sign the site induction record to confirm that they understand and would comply with the context and content of the RAMS and site induction.  By undertaking the site induction in accordance with the RAMS document, the Site Engineer ensured co-operation between personnel on site.
