Applying marine coatings using spray methods

This standard identifies the competences you need to apply marine coatings to various substrates, using manual spray guns, in accordance with approved procedures.  You will be required to access the appropriate contractual and other specifications, to check that these are of the latest issue and to extract all necessary information in order to carry out the coating operations.  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 select the appropriate and/or specified equipment and to ensure that it is correctly set up, maintained and adjusted.  You will be expected to apply a variety of coatings in a number of shipyard and onboard 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 with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.* * 

Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying liquid marine coatings by spray methods.  You will understand the spraying procedures and techniques used and their application.  You will know about the substrates, their preparation requirements, coating materials and their preparation requirements, in sufficient depth to provide a sound basis for carrying out the activities, correcting faults and for ensuring that the coated surfaces are to the required standards and to the customer's expectations. 

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.

1. work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines

2. ensure the material surfaces to be treated are suitably prepared for the finishing operations to be carried out

3. check that the finishing equipment and coatings are set up and maintained at satisfactory operating conditions and levels

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

5. ensure that the treated workpiece achieves the required characteristics and meets the finishing specification
6. deal promptly and effectively with problems within your control and report those that cannot be solved
7. dispose of waste and excess materials in line with agreed organisational procedures
8. shut down the finishing equipment to a safe condition on completion of the processing activities
9. complete relevant documentation in line with organisational
   procedures

---

1. the safe working practices and procedures to be observed when working with marine coatings and spray application equipment (such as general workshop and site safety, appropriate protective equipment, protecting other workers from the effects of the work, safety in enclosed/confined spaces, working at height, use of mobile elevated work platforms (MEWPs), atmospheric controls)
2. how to recognise and deal with emergencies and the procedures to be followed (such as methods of safely evacuating and closing down of compartments in the case of fire or other major incident, first aid, fire fighting and resuscitation of personnel)
3. statutory requirements, risk assessment procedures and relevant requirements of HASAWA, COSHH (such as Approved Codes of Practice (ACOP), The Management of Health and Safety at Work Regulations, The Provision and use of Work Equipment Regulations, The Noise at Work Regulations, the Confined Space Regulations, The Special Waste Regulations, the Pollution Prevention and Control Regulations, The Water Resources Act)
4. 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)
5. the requirements for working in confined spaces and the importance of emergency procedures and safe systems of work (including 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

6. the personal protective equipment (PPE) and respiratory protective equipment (RPE) to be worn during the spraying activity

7. the characteristics of and the applications for, marine coating products (including the use of manufacturers' data sheets, requirements for the application of particular coating systems and contractual specifications)

8. how to carry out currency/issue checks of the specifications you are working with 
9. the need to ensure that the substrates have been prepared correctly for the coatings to be applied
10. the importance of maintaining appropriate environmental conditions for the application and curing of the marine coating products
11. the time intervals that are required between coats and why these must be adhered to
12. the procedures for the handling and safe use of coating materials and solvents
13. the methods used to adjust the viscosity of the product being applied
14. selection of the application equipment to suit the materials and the finish required (to include spray gun selection, HPLV/airless, atomising and air control, tip size, fluid delivery rates and fan angle)
15. the correct grounding and earth continuity of the equipment
16. the importance of checking lines for damage and for kinks; the use of a 'daily check list'
17. the requirements for cleaning pumps, filters, surge chambers and the need to top up the oil cup
18. 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)
19. the techniques required for the application of marine coating products to a variety of surfaces
20. the requirements for working afloat, on outer bottoms and at heights
21. the importance of avoiding overspray; the need for containment and for exclusion zones
22. the procedure to contain and to clear away spillages.
23. the identification of faults in application and their causes and correction (to include distorted patterns, tailing, dry spray, over spray and pinholing)
24. simple non-destructive testing procedures to ensure that colour, gloss, adhesion and other required performance qualities are achieved
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
