7.1 General

Everyone working in __ facilities will adhere to local and statutory regulations and the __ HSE manual. Paint manufacturers Safety Data Sheets will be available and instructions for handling and storage will be followed. Fire extinguishers will be placed in accessible locations close to the storage, application and mixing areas.

8 SURFACE PREPARATION:

8.1 Material Abrasive will be Garnet of a minimum mesh 30 size to achieve the specified blast standard of SSPC-SP10 and, profile amplitude. The garnet will be dry and oil free and will conform to permissible soluble salt content levels. Average profile height shall be 40 – 80 microns.

8.2 Equipment Mobile air compressors will supply compressed air and the air will be dry and oil free with a nozzle pressure of 100 PSI. 200ltr mobile blast pots with remote control handles (dead man) will be used. Equipment will be earthed and hoses will be carbon impregnated to prevent static electricity build up. Venturi shaped, tungsten carbide lined nozzles will be used and replaced when wear reaches 50% of its original diameter.

8.3 Access Access platforms will be of tubular scaffolding, which will be erected as and when required. Wherever it is possible the scaffold will be erected so as not to impede or hinder access for correct surface preparation and coating application.

Sheet of Sheets

8 / 24

8.4 Pre-start Inspection

Prior to starting surface preparation all items will be checked for faults that could be deemed to be detrimental to the paint coating i.e. rough welds, burrs, weld splatter, laminations etc. Faults will be rectified before surface preparation commences. See section 7.0.

8.5 Degreasing Any oil or grease will be removed by scraping off heavy deposits, brushing on degreaser or emulsion cleaner followed by high-pressure fresh water washing. The use of solvents for degreasing of large areas cannot be considered a safe practice however, solvent swabbing may be considered for removing small spots of oil or grease.

8.6 Soluble Iron Salts Before blast cleaning all items will be tested for soluble salts as per specification parameters to reduce the possibility of salt being forced into the profile by high velocity blasting. If salt contamination is above the acceptable level fresh water washing will be done until an acceptable level is achieved. This test can be repeated before application of primer/first coat if required.

8.7 Protection Items attached to or in the vicinity of the surface to be painted, which do not require painting will be protected during the whole operation i.e. finish coated items, flange faces, bearings, nameplates, machined faces etc. Edges to be welded at a later date will not be painted after blasting they will be taped to 50mm each side of the weld area.

8.8 Environmental Conditions Blast cleaning will not take place under the following conditions: a) Rain, fog, mist, airborne dust or sand or if there is moisture on the surface. b) Steel temperature is within 5 deg C of the dew point. c) Steel or ambient air temperature is below 10 deg C. d) Relative humidity is greater than 80%. e) If there is a possibility of the above occurring within 2 hours or less.

Blast cleaning will normally take place between the hours of 0700 and 1800. Blasting outside of these hours will only take place in exceptional circumstances if conditions permit or the environment can be controlled with de-humidifiers.

8.9 Blast Cleaning Experienced blasters will perform abrasive blast cleaning and the standard will conform to the requirements of the relevant systems specified herein and, manufacturers data. Any defects uncovered by blasting will be rectified and the area re-blasted to standard.

8.10 Cleaning After blasting the surface will be thoroughly cleaned by one or more of the following methods. a) Stiff bristle brushes b) Clean dry air blowing. c) Vacuum cleaning.

9 COATING APPLICATION

9.1 Materials One manufacturer will supply all paint materials and thinners. Multiple coat systems will be of a different colour for each coat. Paintwork shall be carried out in accordance with the procedure established by this specification and by the paint manufacturer with particular attention to the solvent , mixing operation , drying time before another coat may be applied and the tools necessary for application.

9.2 Storage All paint materials and thinners will be stored in an air-conditioned container, according to the manufacturers recommendations and data sheets. Special attention will be paid to the safety aspect of storing paints. The following will be monitored and recorded. a) Shelf life. b) Batch numbers. c) Labelling of tins. d) Condition of tins i.e. broken seals or damaged tins.

9.3 Equipment Airless or conventional spray pumps with paint manufacturers recommended nozzle sizes and pressures will be used. Brushes and rollers will be used for stripe coating and areas that may be inaccessible to the spray gun. All equipment will be thoroughly cleaned before and after use with manufacturers recommended cleaner/thinner. Wet film combs will be used to control the uniformity of film thickness.

9.4 Environment Conditions Application will not take place under the following conditions: a) Rain, fog, mist, airborne dust or sand or moisture on the surface. b) Steel temperature is within 5 deg C of the dew point. c) Steel temperature is below 10 deg C d) Steel temperature is above 50 deg C. e) Relative humidity is greater than 80%. f) If there is a risk of any of the above occurring during the application or surface

drying of the coating.

9.5 Mixing Paint will be checked before mixing for any deterioration during storage. Any doubts about the integrity of the material will be brought to the attention of the manufacturer and advice will be sought on the course of action. Thinning will only take place on the manufacturers recommendation and to their specified maximum volume. Only a volume of paint, will be mixed, that can be used within the pot life and paint that has exceeded the pot life will not be used. Paint will be thoroughly mixed using mechanical power stirrers.
