Each candidate will receive a comprehensive manual that includes copies of relevant standards. The 1-day classroom portion begins with an overview of all surface preparation methods and basic safety followed by an intensive discussion of equipment and productivity and guidelines for using SSPC-VIS 4 to achieve the SSPC/WJ cleaning levels. Day 2 begins with a brief review of the first day’s classroom lecture before the written exam. 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.
During the hands-on skill assessment, the instructor will observe each candidate waterjetting and grade them on achieving WJ-2 Very Thorough or Substantially Clean Surface with the proper cleaning techniques. Candidates will also be graded on wearing proper PPE and their ability to identify the major components of the waterjetting equipment used.
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 waterjetting certification and CEUs must attend all 16 hours of the certification and pass the written exam with a score of 70% and the hands-on exam with a score of 90%.
