Providing Your Own Training for the Marine Plural Component Program (MPCAC) 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 marine plural component. 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 training and only have SSPC come to your facility to proctor the exams, please contact Jennifer Merck (firstname.lastname@example.org 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 MPCAC Lecture. It is up to your company to have your candidates prepared to answer questions on the exam in the following areas:
1. Introduction & Overview of Plural Component Spray Technology
- Benefits of plural component application
- Definition of a high-solids coating
- Plural component application systems
- Methods for mixing material or coating components (e.g. Part A, Part B)
2. Equipment Operational Systems
- Feed system
- Pump/proportioning system
- Heating system
- Mixing manifold system
- Spray gun
- Running out of material
- Insufficient spray pressure
- System speeds up or runs erratically
- Improper pressure gauge readings
- Material not heating properly
- Abnormal spray pattern (tails and fingers)
- No fluid in lines
4. Characteristics Of Plural Component Coatings*
- Basic constituents
- Film formation
- Two-component epoxies
- Successful application factors
- Solvent-based vs. High-solids epoxies
- NAVSEA-approved high-solids epoxies
- Pointers for use
It is up to your company to have your candidates prepared to demonstrate hands-on spraying of plural-component materials. 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 spraying plural-component materials.
The hands-on session consists of the candidates operating the plural component pump and spraying plural component materials.
It is the responsibility of your company to prepare the candidates to know how to operate the PC spray pump being used. The candidates must also know how to trouble shoot problems.
During the hands-on skill assessment the candidates will be evaluated on:
- Their ability to operate the equipment
- Their ability to troubleshoot the equipment
- Their ability to spray the material on steel test panels or test areas according to the PDS requirements
- Their ability to measure WFT
- Their ability identify key components of the pump
**Please make sure you have enough personal protective equipment (PPE) on-site for the hands-on part of the course. Make sure you have enough hard hats, coveralls, leather gloves, earplugs, etc. (You must supply this or make certain you let the students know they have to bring their PPE.)**
The following are some suggestions that will help the MPCAC Exam run smoother and guarantee that everyone gets to spray:
Please make sure 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 hands-on spraying 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 spraying per one instructor.
There needs to be enough room to spray simultaneously safely.
The key to making this all run smoothly is to have enough PPE and spraying equipment.
If you supply a full-face respirator then you also need to provide antiseptic wipes to disinfect the respirators between uses.
