Collection <strong>of</strong> examples <strong>of</strong> risk assessments and <strong>of</strong> some possible tools<br />
supporting the <strong>CSM</strong> Regulation<br />
<br />
associated hazards can be understood what risks they are expected to control, without<br />
the need to go back into the related safety analyses.<br />
(b) the risk acceptance principle used to control the hazard in order to support the mutual<br />
recognition and help the assessment body to assess the correct application <strong>of</strong> the <strong>CSM</strong>;<br />
(c) a clear in<strong>for</strong>mation on its status: this field indicates whether the related hazard/safety<br />
measure is still open or controlled/validated.<br />
(1) an open hazard/safety measure is tracked until it is controlled/validated;<br />
(2) reciprocally, the controlled/validated hazards/safety measures are not tracked<br />
anymore unless significant changes in operation or in maintenance <strong>of</strong> the system<br />
occur: see point [G 6](b) in section 2.1.1. If this happens:<br />
(i) the <strong>CSM</strong> is applied again on the required changes in compliance with the<br />
Article 2. See also point [G 6](b)(1) in section 2.1.1;<br />
(ii) all controlled hazards and safety measures are reconsidered in order to<br />
check that they are not impacted by the changes. If impacted, the related<br />
hazards and associated safety measures are re-opened and managed again<br />
in the hazard record;<br />
It could happen that different safety measures are implemented instead <strong>of</strong> the<br />
ones registered in the hazard record (e.g. <strong>for</strong> cost purposes). The implemented<br />
safety measures are then registered in the hazard record with the evidence/<br />
justification why they are appropriate and the demonstration that with these<br />
measures the system complies with the safety requirements.<br />
(d) the reference to the associated evidence controlling a hazard or validating a safety<br />
measure. This field enables to find later the evidence having permitted to control the<br />
hazard and to validate the associated safety measure(s);<br />
A hazard could be controlled in the hazard record only when all the associated safety<br />
measures, linked to the hazard, are validated be<strong>for</strong>ehand;<br />
(e) the organisation(s) or entity (ies) responsible to manage it.<br />
C.16.1.3. Another example <strong>of</strong> possible content <strong>of</strong> a hazard record is given in the Appendix A.3. <strong>of</strong> the<br />
EN 50126-2 guideline {Ref. 9}.<br />
