THE INTERNATIONALLY RECOGNIZED SPRAYED CONCRETE OPERATOR CERTIFICATION
The ESCOT™ certification is a standard created by Edvirt AB back in 2012. It is a proof that persons have gone through and passed a standardized sprayed concrete operator training program. The program includes both theory and practice and operators are evaluated objectively on their skills.
The certificate is valid for 5 years.
The program's theory module includes the following subjects:
The purpose of sprayed concrete
The purpose of training sprayed concrete operators
Rock and ground support
Application and spraying technique
Health, safety and environment
The theory can be done online through Edvirt Online Academy™ or in a classroom format. The theory is specified to take approximately 8 hours to finish including a test with 20 questions. Attendees need at least 75 % correct answers to pass the test and theory module.
The practical module includes training and tests with a sprayed concrete simulator (VR Shotcrete Simulator™), that has been scientifically validated by an independent body (University of Technology in Luleå). The operators need to show that they are qualified by passing 17 assignments within the following fields:
Startup and shutdown procedure
Safe spraying (operator position, avoiding fall-outs etc.)
Use of remote control and robot maneuvering
Spraying angle and distance
Concrete adhesion and rebound
Pump and accelerator dosage
Preparation and washing rock surface
Spraying small and large areas
Thickness control and waste minimization
The practical module is specified to take 16-40 hours dependent on the skill level of the attendee. The attendee needs to finish all assignments to pass the practical module.
