URN: SEMME2102
Business Sectors (Suites): Marine Engineering Suite 2
Developed by: Enginuity
Approved on: 2018

Overview

This standard identifies the competences you need to apply holding primer to various substrates, using manual spray guns, in accordance with approved procedures. You will be required to obtain all necessary information in order to carry out the spraying of the holding primer. You will be required to check that all surfaces to be coated have been prepared, in accordance with the process specification and that any necessary exclusion, containment, masking, protection and ventilation requirements are implemented. You will be expected to use the appropriate and/or specified equipment and to ensure that it is correctly set up, maintained and adjusted. You will be expected to apply the coatings in a number of shipyard and shipboard environments.

Your responsibilities will require you to comply with organisational policy and procedures for the spray coating activities undertaken and to report any problems with these activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work to instructions, alone or in conjunction with others, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will be sufficient to provide a sound basis for your work and will provide an informed approach to applying holding primer by spray methods. You will have an understanding of the spraying procedures and techniques used and their application. You will know about the substrates and their preparation requirements, holding primers and their preparation requirements, in sufficient depth to provide a sound basis for carrying out the activities and for ensuring that the coated surfaces are to the required standards.

You will understand the safety precautions required when carrying out the spraying operations. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and to others in the workplace.

  4. carry out the treatment process in accordance with operating procedures and the component specification

  5. apply holding primer by spray methods using appropriatemethods and techniques

  6. ensure that the treated workpiece achieves the required characteristics and meets the finishing specification

  7. deal promptly and effectively with problems within your control and report those that cannot be solved
  8. dispose of waste and excess materials in line with agreed organisational procedures
  9. shut down the finishing equipment to a safe condition on completion of the processing activities

  3. the hazards associated with the storage of, the preparation of, and the disposal of marine coating products (including the information to be found in manufacturers' data sheets and in Chemical Hazard Information and Packaging for Supply (CHIPS) data sheets)
  4. the requirements for working in confined spaces and the importance of emergency procedures and safe systems of work (including safe evacuation, closing down compartments, permits to work, required air quantities (RAQs) and local exhaust ventilation (LEV), to maintain safe conditions; the provision of adequate and safe lighting and avoidance of sources of ignition)
  5. how particular procedures and materials, can result in a compartment or space (such as an accommodation space or tented enclosure) becoming a confined space
  6. the importance of having regular medical examinations when using solvent based materials
  7. the personal protective equipment (PPE) to be worn during the holding primer spraying activity
  8. the use of manufacturers' data sheets, requirements for the application of particular primer systems and contractual specifications
  9. the need to ensure that the substrates have been prepared correctly for the primer to be applied
  10. the importance of maintaining appropriate environmental conditions for the application and curing of the marine coating products
  11. the procedures for the handling and safe use of coating materials and solvents
  12. the use of paint thinners to adjust the viscosity of the product being applied
  13. selection of the application equipment to suit the materials and the finish required (to include spray gun atomising and air control, tip size, fluid delivery rates and fan angle)
  14. the correct grounding and earth continuity of the equipment
  15. the importance of checking lines for damage and for kinks; the use of a `daily check list'
  16. the requirements for cleaning pumps, filters, surge chambers and the need to top up the oil cup
  17. the requirements for cleaning spray guns (including the cleaning of the diffuser, tip and tip guard, the flushing of the gun and of the lines, the lubrication of the needle)
  18. the techniques required for the application of holding primer to a variety of surfaces
  19. the requirements for working afloat, on outer bottoms, and at heights
  20. the importance of avoiding overspray; the need for containment and for exclusion zones
  21. the procedure to contain and to clear away spillages
  22. the identification of faults in application and their causes and correction (to include distorted patterns, tailing, dry spray, overspray, and pinholing)
  23. simple non-destructive testing procedures to ensure that adhesion and other required performance qualities are achieved
  24. why tool/equipment control is critical and what to do if a tool or piece of equipment is unaccounted for on completion of the activities
  25. minimising and handling waste materials (including the environmental impact of the materials you are using and the minimisation of this impact)
  26. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
