Prerequisites

The following items must be submitted no later than two weeks before the scheduled course: C7 Prerequisite Form.

​

Each student must also obtain written confirmation from his or her employer's human resource manager that the student has completed a minimum of 800 documented hours of abrasive blasting experience in an industrial or marine environment prior to qualifying for the C7 Certification.

​

​

Course format/notes

The course starts with a classroom overview of fundamentals in preparation for the written exam, which is then followed by a thorough review and walk-through of abrasive blasting and portable centrifugal blasting equipment setup and operation. Once the written exam is completed, a tailgate safety meeting is conducted to review safe gun operating procedures, including troubleshooting and signals, before the hands-on session takes place.

​

Following the equipment review, the instructors will observe each student as they describe setup procedures and demonstrate their blasting skills. This format provides candidates with prior blasting experience an opportunity to achieve blaster certification. This program is not intended for inexperienced blasters. Each candidate will receive a comprehensive manual that includes copies of useful handouts and industry blast cleaning standards. Those who successfully complete the blaster certification program will receive a certificate and wallet identification card from AMPP.

​

The written, multiple-choice exam is worth a maximum of 100 points. The hands-on evaluation is also worth a maximum of 100 points.

​

Candidates wishing to achieve the C7 Certification and CEUs must attend all 16 hours of the course and pass the written exam with a score of 70% and the hands-on exam with a score of 90%.

​

Note: Students who do not want to receive the C7 Certification can receive a certificate of attendance by attending the lecture portion of the training and observing the blaster demonstration.
