European Railway AgencyGuide <strong>for</strong> <strong>the</strong> <strong>application</strong> <strong>of</strong> <strong>the</strong> CSM Regulation to be evaluated according to Article 4 in order to determine whe<strong>the</strong>r it is significant. If <strong>the</strong>change is significant, it shall be handled in compliance with <strong>the</strong> CSM.4.2. Exchange <strong>of</strong> in<strong>for</strong>mationAll hazards and related safety requirements which cannot be controlled by one actoralone shall be communicated to ano<strong>the</strong>r relevant actor in order to find jointly anadequate solution. The hazards registered in <strong>the</strong> hazard record <strong>of</strong> <strong>the</strong> actor whotransfers <strong>the</strong>m shall only be “controlled” when <strong>the</strong> evaluation <strong>of</strong> <strong>the</strong> risks associatedwith <strong>the</strong>se hazards is made by <strong>the</strong> o<strong>the</strong>r actor and <strong>the</strong> solution is agreed by allconcerned.[G 1] During <strong>the</strong> hazard management, it is possible that some hazards cannot be controlled, and<strong>the</strong> associated safety measures cannot be validated, in <strong>the</strong> hazard record by one actoralone. In such cases a process or procedure may be necessary in order to identify how<strong>the</strong>se hazards can be controlled by <strong>the</strong> actors that are involved in <strong>the</strong> project. This mayinvolve ei<strong>the</strong>r:(a) <strong>the</strong> various actors discussing and agreeing <strong>the</strong> outcome in order to control <strong>the</strong> relatedhazards and to validate <strong>the</strong> associated safety measures in <strong>the</strong> hazard record, or.(b) <strong>the</strong> transfer <strong>of</strong> <strong>the</strong> related hazards and <strong>the</strong> associated safety measures into <strong>the</strong> hazardrecord <strong>of</strong> <strong>the</strong> actor responsible <strong>for</strong> implementing, verifying and validating <strong>the</strong>m. Forexample, an operational procedure could be needed <strong>for</strong> mitigating a risk when <strong>the</strong>re isnot technical/design measure possible. This exchange <strong>of</strong> safety in<strong>for</strong>mation complieswith <strong>the</strong> requirement in <strong>the</strong> last paragraph <strong>of</strong> <strong>the</strong> abstract g.0 <strong>of</strong> <strong>the</strong> assessment criteriawhich is set out in point [G 2] <strong>of</strong> section 4.1.1.[G 2] When a safety measure is not fully validated:(a) a clear restriction <strong>of</strong> use (e.g. operational mitigation measures) needs to be elaboratedand registered in <strong>the</strong> hazard record;(b) as this restriction <strong>of</strong> use is a fur<strong>the</strong>r or an alternative safety measure, its appropriatenessto control adequately <strong>the</strong> risk needs to be justified;(c) <strong>the</strong> restriction <strong>of</strong> use and <strong>the</strong> associated hazard and risk need to be exported ortransferred to <strong>the</strong> actor responsible <strong>for</strong> implementing, verifying and validating thatrestriction <strong>of</strong> use (<strong>for</strong> example to RU if it is an operational constraint).
