Introduction to Safety Hazards

When alterations are undertaken on existing signalling installations, the infrastructure controller should consider whether certain retrospective safety work, both on the parts of the installation being altered and on those parts of the installation not being altered, should be carried out.

A fully documented process of risk assessment should be conducted if the Route Asset Manager (S&T) considers that the work is not merited by the reduction of risk that would be achieved.

The Route Asset Manager (S&T) should keep a record of which safety hazards have been addressed at each installation, and those that have not been addressed.
