Railway work is very strictly controlled and detailed procedures have evolved over the years to cover almost every activity in order to minimise health and safety risks.

Isolations work is fairly routine and repetitive and involves long waiting period between the application of earths and their removal.

LPA carried out a due diligence exercise involving review of procedures and observing an isolation and restoration exercise. The purpose was to be able to confirm that all the required formalities and procedures were implemented in practice so that a better understanding could be gained of the potential risks.
