The Nozzle operator is ultimately responsible for the quality of sprayed concrete. In the interest of the contractor, he operates and maintains the equipment and ensures safety at the workplace. EFNARC has recognized the importance of trainings for Nozzlemen and has developed an internationally recognized certification scheme.
The Nozzle operator Certification Scheme with recognised EFNARC Examiners was introduced in 2009. In view of the rapid development of modern robotic application equipment and new concrete technology, the need for education and training has increased.
With the EFNARC Nozzle operator Certificate, a standardized quality framework for training and assessment was created, combining theory and practice with Virtual Reality (VR) simulator technology.
The Nozzle operator certificate is obtained after attending and passing the course and handing in proof of minimum 40 days robotic spraying experience. Inexperienced operators will be able to attend the course and come back to do Module 5 once they can prove the required spraying experience.
Additionally, the course can be booked at any time with a minimum attandance of 2 persons as we have the simulator permanently on premises now.
MODULE 1 – THEORY SESSION
The course includes classroom theory during a full day. The theory involves both basic and advanced theory (concrete and spraying technology, application, surface and curing, testing and HSE).
MODULE 2 – THEORY EXAM
Each course participant individually completes a theory exam online which includes 30 multiple-choice questions.
MODULE 3 – TRAINING AND ASSESSMENT IN VIRTUAL REALITY (VR)
The participants go through 10 pre-defined scenarios and assessments on VR-simulators.
MODULE 4 – WORK EXPERIENCE
The course participant hands in a document showing minimum 40 days of spraying experience. The experience can be gained prior to or after the course, but only those with experience will go through the last day of the course and perform the assessment.
MODULE 5 – ASSESSMENT
Practical assessment of each participant with a real spraying robot. This module is performed on day 5 of the course for participants that have handed in the work experience documents. Novice operators will do module 5 at a later stage (most probably on their own site).
