Providing Your Own Training for the Water Jetting Program (C13) Exam
Companies that have already trained their workers in the topics listed below may elect to forgo the SSPC classroom-training component and have an authorized SSPC proctor oversee a written exam and a hands-on certification session in waterjetting. The SSPC exam proctor will not review any of the training topics with the students. It will be assumed that they have already been trained and are ready to be tested.
If you would like to forgo the SSPC classroom review component of the certification process and only have SSPC come to your facility to proctor the written and hands on exams, please contact Jennifer Merck (email@example.com or 877-281-7772 ext 2221) to request a cost proposal for this option.
**It is your company’s responsibility to train the candidates. When SSPC comes to your location we will proctor the 1-hour multiple-choice exam and the hands-on exam. The instructor will not review any material with the students.**
Lecture Topics & Suggestions
The following topics are normally covered in SSPC’s C13 Overview Lecture. It is up to your company to have your candidates prepared to answer questions on the exam in the following areas:
1. Surface Preparation Overview
- All major surface preparation methods used to prepare steel for application of protective coatings
- Surface defects and contaminants
- Surface preparation standards, methods, and visual aids
- Waterjetting cleanliness levels
2. Basic Safety Awareness Overview
- Personal safety
- Jobsite safety
- Mechanical safety
- Electrical safety
- Waterjetting safety
3. Waterjetting Equipment Overview
- Types and functions of waterjetting equipment and how to operate the equipment with maximum productivity.
4. Review of Waterjet Cleaning to SSPC SP-12/NACE 5 and Use of SSPC VIS 4/NACE VIS 7
- SSPC SP-12/NACE 5 waterjetting cleanliness levels
- SSPC VIS 4/NACE 7
- Flash rusting
- Soluble salts
5. Wet Abrasive Blast Cleaning*
*For those requiring training in this area
- System types
- Surface preparation
It is up to your company to have your candidates prepared to demonstrate hands-on waterjetting. Information about what will be happen during the Hands-On Session is as follows:
The objective is to have the candidate’s set up, suit up, and demonstrate their skills at UHP waterjetting.
The final hands-on session consists of actual UHP waterjetting. The students will suit up in preparation for waterjetting. After the equipment is started, waterjetting will begin, with the students participating in the actual operation.
Each candidate will waterjet for approximately 15-30 minutes at the discretion of the proctor. During the hands-on waterjetting session, candidates will be required to:
- Identify the major components of the ultra high-pressure waterjetting equipment
- Perform tests on the waterjetting equipment
- Demonstrate cleaning techniques
- Clean a test specimen according to SSPC SP-12/NACE 5 and achieve the required visible cleanliness
The following are some suggestions that will help the C13 course run smoother and guarantee that everyone gets to waterjet:
Please make sure you each candidate has appropriate personal protective equipment (PPE) on-site for the hands-on part of the evaluation, per OSHA, equipment manufacturer SOP’s and your company safety procedures. Make sure you have enough blast helmets, coveralls, leather gloves, earplugs, etc. (You must supply this or make certain you let the students know they have to bring their PPE.)
The waterjetting part of the program can move along quickly if it's done in an assembly-line fashion. There should be one (1) "experienced" contractor representative and one (1) instructor suited with the proper PPE. The ratio should be one candidate waterjetting per one instructor.
There needs to be enough room to waterjet simultaneously safely.
The key to making this all run smoothly is to have enough PPE and waterjetting equipment.
If you supply a full-face respirator then you also need to provide antiseptic wipes to disinfect the respirators between uses.
