According to IRATA TACS 4.3.4 requirements, rope access technicians attending re-certification or upgrading to a higher level are required to present a properly completed IRATA Logbook on the first day of training.

In the event of a lost Logbook, an application for a replacement must be submitted through IRATA before the training begins:

The new Logbook must already be in the participant’s possession on the first day of training. Please note that the replacement process may take up to 3 weeks.

Exception:
For Level 1 technicians attending re-certification training, it is possible to order a replacement Logbook during the course.

In such cases, the participant is required to immediately inform the instructor about the missing Logbook. Based on this information, an appropriate product will be made available in the online store for purchase.
