Use of Unapproved Components<br />
The use of unapproved cables and unapproved ETPs can negatively impact the safety integrity<br />
of the safety function and the compliance with the applicable safety standards. This causes a<br />
liability issue in the event of a plant incident.<br />
The use of such unapproved components can also impact the availability of the safety system<br />
by causing false trips in the plant. This results in unnecessary economic loss <strong>for</strong> the plant.<br />
