This foundational level encompasses solely theoretical knowledge and does not cover practical skills. Level 1 does not grant the holder the right to work with the E*STAR system. Level 1 is not concluded with a test or any other form of assessment, and no certificate is issued for this level; the student receives a confirmation of participation and may thus proceed to study further levels of E*UNI.
CTA encompasses theoretical knowledge and practical skills in the classroom and the field. CTA authorises the holder to work with the E*STAR system. CTA doesn’t authorise the holder to program and fire an E*STAR blast. Successful completion of CTA requires passing a knowledge test and practical skills examinations. At the end of the course, the student must demonstrate their skills in two blasts without help or intervention from an instructor.
CTO includes theoretical knowledge and practical skills in the classroom and 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.
CTS includes theoretical knowledge and practical skills in the classroom and the field. CTS authorises the holder to work with the E*STAR system, carry out E*STAR blasting operations, and perform troubleshooting. Additionally, the holder is entitled to coach other students at levels 1, 2, and 3. To successfully complete CTS, one must pass a knowledge test and practical skills examinations.
CTD comprises solely theoretical knowledge. CTD is not concluded with a test or any other form of assessment. CTD does not authorise the holder to perform blasting operations. Upon successful completion of the course, the student receives a CTD certificate, which has unlimited validity. This certificate does not replace a shotfirer’s license.
CTT includes theoretical knowledge and practical skills in the classroom and the field. CTT authorises the holder to coach other students at all levels of E*UNI. To successfully complete CTT, one must pass a knowledge test and practical skills examinations. Furthermore, the student must execute 30 E*STAR blasts within 3 months (especially for tunnels and underground mines) or 20 E*STAR blasts within 12 months (especially for surface blasting works).
