Level 3 – CTO (Certificate to Operate) is the minimum qualification required to fire an E*STAR blast.
CTO includes both theoretical knowledge and practical skills in the classroom and in the field. The CTO authorises the holder to work with the E*STAR system and to carry out E*STAR blasting operations. Successful completion of CTO requires passing a knowledge test and practical skills exams. At the end of the course, the student must demonstrate their skills in three blasts without help or intervention from an instructor. These three blasts must be conducted consecutively, with the maximum time between them determined by the respective instructor.
Upon completing the course, the student receives a CTO certificate, valid for 24 months from the date of issuance.
In addition to the knowledge and skills acquired in previous levels, the student will learn:
- Programming
- Data transferring
- Arming
