The authorising officer responsible shall inform the data subjects that data concerning them may be included in the EWS and to whom the data may be communicated. This general information shall be communicated in writing, in particular, in the calls for tender, calls for proposals, prize contests and in the absence of calls before awarding contracts or grants.

The authorising officer responsible who requests the registration of a warning shall be responsible for the relations with the person whose data are introduced into the EWS. He/she shall respond to requests from a person concerned to rectify inaccurate or incomplete personal data and to any other requests or questions from this person.

A person may also request in writing information from the accounting officer on whether he/she is registered in the EWS.

The accounting officer shall provide this information unless the authorising officer responsible, in agreement with OLAF where appropriate decides that restrictions of Article 20(1) of Regulation (EC) No 45/2001 apply.

Removed warnings shall be accessible for audit and investigation purposes only and shall not be visible for the users of the EWS.

However, personal data contained in warnings referring to natural persons shall remain accessible for such purposes only for five years after the removal of the warning.
